The most important factor of a sustainable building is the source of quality construction steel. Depending on the property of each project, the contractor will choose some criterias to evaluate construction steel. Below is a list of common criteria for evaluating the quality of construction steel.Construction steel quality standardsThere are countless different types of steel on the market today, in order to create a common uniformity in the steel production process, quality standards have been issued. Manufacturing mills will often rely on these quality standards to adjust the specifications to ensure the quality of the steel grade is in the best condition.Three common quality standards including Vietnamese, American and Japanese standards are applied to steel constructions such as plain bar and rebar. In which, when the product meets Vietnamese standards, construction steel is considered as standard steel and is completely suitable for construction projects.TCVN - Vietnam steel standardVietnam confirms quality standards for steel grades is abbreviated in the form of TCVN, of which there are 4 general standards: TCVN 1651-1:2008, TCVN 1811_2009 (ISO 14284-1996), TCVN 6287_1997, TCVN 7937-1-2013.The plain bar steel used to make reinforced concrete and on each of them are marked CB240-T, CB300-T and CB400-T. Similar to plain bar steel, rebar steel also owns 3 standard steel grades including CB300-V, CB400-V, CB500-V, CB600-V. The numbers in the symbol will represent the strength of the steel. Specifically, the CB300-T series will indicate the value of strength is up to 300N/mm2, meaning that a steel bar with a cross section of 1mm2 will withstand a tensile force of up to 300N (equivalent to 30kg).ASTM - American steel standardThe American Standard is identified by its common abbreviation ASTM, will focus on key topics such as specifications, testing, and grading guidelines. The American standard applied in the current range of construction concrete steels is ASTM A615/A615M with 3 steel grades including GR40, GR60 and GR75.Most steel grades according to American standards are highly appreciated for their outstanding hardness when all 3 steel grades GR40, GR60 and GR75 possess tensile strengths of 420 MPa, 620MPa and 695MPa. Having the high tensile strength will be a plus point of this standard for building framing applications because they provide extremely good loading.JIS - Japanese steel standardThe Japanese standard is also one of the familiar standards in the steel industry with the abbreviation JIS. Currently, two popular Japanese standards are applied in construction steel including JIS G3505 - 1996, JIS G3112 - 1987.Construction steel specificationAnother important criterion in the selection of construction steel is the appropriate size including diameter, length and volume. Knowing the construction steel diameter will help the contractor easily calculate the required volume of construction steel for the project, especially for large projects that always require meticulousness and calculation in detail.If the contractor is not careful in choosing the right size, it is easy to make the structure weak because of unbalanced transmission forces in some loading parts. Famous construction steel suppliers in the Vietnam market such as Hoa Phat, Pomina, Viet Italy, ... are at risk of being faked as poor quality versions. Normally, the fake version of construction steel will have a smaller size from 0.5 - 0.8mm than the authentic one.Specification of steel standard TCVN 1651-2008Outside diameter桅6桅8D8D10D12D14D16D20D25D32D36D40D50Cross section(mm2)28.350.2750.277.8511315420131449180410181 2571 694Specific weight (kg/m)0.2220.3950.3950.6170.8881.211.582.473.856.317.999.8615.42Tolerance specific weight (%)卤8卤8卤8卤6卤6卤5卤5卤5卤4卤4卤4卤4卤4 Specification of steel standard JIS G3112 - 1987Outside diameterD10D13D16D19D22D25D29D32D35D38Cross section(mm2)71.33126.7198.6286.5387.1506.7642.4794.2956.61140Specific weight (kg/m)0.560.9951.5592.2493.0393.9785.0436.2347.5098.949Tolerance specific weight (%)卤6卤6卤5卤5卤5卤5卤4卤4卤4卤4 Specification of steel standard ASTM A615/ A615M-08Outside diameterD10D13D16D19D22D25D29D32D36Cross section(mm2)711291992843875106458191006Specific weight (kg/m)0.560.9941.5522.2353.0423.9735.066.4047.907Tolerance specific weight (%)卤6卤6卤6卤6卤6卤6卤6卤6卤6 Steel origin and the market priceThe standard steels must be the steel lines having clear origin, usually the manufacturer will attach labels showing characteristic symbols and brand names on each steel bundle.In addition, quality construction steels from reputable brands will always have a fixed price and the retail price will be listed from the manufacturer. If the price of steel is too low compared to the factory's selling price, it means that the quality of the steel will not be guaranteed.Quality construction steel must come from a reputable supplierBesides considering the quality criteria, choosing a reputable steel supplier is also an important factor to help get good construction steel.

For decades, metal corrosion problems have always been one of the challenges for steel manufacturers. The making use of a steel coating method to create a protective layer for the steel core is considered the most effective process. Currently, there are many methods of steel coating and these types possess different characteristics with advantages.The role of the steel coating method for the durability of productSteel is a product derived from metal ores, so wear and rust will occur if we leave them for a long time in the environment. Therefore, manufacturers often conduct steel coating stages before putting them on the market to create a protective layer for the steel surface to help resist external effects.Prevent rust and oxidizing agentsZinc components present in the coating layer when exposed to oxygen and carbon gas, it will form a layer of zinc carbonate (ZnCO3). Thanks to this chemical reaction, the steel core can minimize approaching oxygen, thereby avoiding corrosion and rust.Keep the surface of the product in top conditionCoatings not only strengthen the steel, but they also support the surface of the product in its best condition by resisting scratches or chipping.Improved loading capacity Steel coating method can help enhance the loading capacity of steel, which has been proven by several studies. Specifically, components such as aluminum, chromium can increase the mechanical properties of steel when they can deposit crystals through the surface, thereby playing a role in increasing the solidity.Savings cost for long-termAlthough galvanized steel products will have a high initial cost, in terms of long time for use, they help optimize costs significantly. Thanks to the durability as well as the limiting surface oxidation, users will not have to spend a lot of money on maintenance as well as replacing new products periodically.5 most common steel coating methods in the manufacturing industryAll current steel products before being put on the market will have to go through steel plating stages to improve durability. Currently in the steel manufacturing industry, manufacturers often apply 5 common coating steel methods and each method has its own characteristics and different applications.Hot dipped galvanizedGalvanizing method mainly refers to dipping the steel into a hot zinc bath. Through this method, the outer layer of the steel is melted into an alloy with zinc under high temperatures of up to nearly 500 degrees Celsius. As soon as the zinc and steel start to react with each other, the operator will put them out of the tank and let it dry, normally hot dip galvanizing will take place within 30 to 40 minutes.Thanks to dipping the entire steel into the zinc solution, the steel coatings are completely wrapped around the surface as well as firmly adhered to the core steel layer, making the zinc layer difficult to peel off. The hot-dip galvanizing method is used by many manufacturers because it brings high economic value along with simple practical operation and does not require much technical calculations.Steel coating method with electrogalvanizationContrary to hot-dip galvanizing, electrolytic galvanizing will not directly immerse the product in a hot zinc bath, but the manufacturer will use equipment to spray zinc solution directly on the steel. Spray solutions contain a large amount of zinc ions with a positive charge while the surface of the steel product has a negative charge, when the two charges approach together, they will form an extremely tight zinc coating.Usually the product will be hung or carefully positioned to make the handler spray the solution in the most convenient way. The first special feature of the plating process is that it takes place quickly, it's only about 5 or 10 minutes. Electrolytic steel coating method is considered to be quite safe when the handler does not have to be exposed to high temperature solutions, limiting dangerous incidents. The most common application of this method is mainly in electronic components or interior decorations.However, the electrogalvanization method produces a coating that is neither thick nor evenness compared to the hot-dip galvanizing method. In addition, the average thickness of electroplating is about 15-20 micrometers. Although electroplating products still maintain good rust and oxidation resistance, they are inferior to other products, especially products coating by hot dip galvanizing process.Thermal sprayingThermal spraying is a term that refers to the steel coating method with molten liquid droplets that form a mist over the surface. Coating materials usually exist in powder or wire form, then they will be heated through fire, plasma jets or electric arcs, when the material reaches a molten state, it will be sprayed directly onto the surface. Under the influence of heat energy and electrical conductivity available in the material, the solution particles stack on top of each other and adhere to the steel surface.Thermal coating will help steel reach an ideal plating thickness from 20 micrometers to several millimeters depending on the needs of the manufacturer. By providing a wide range of coating thicknesses, thermal spray coating can be applied to a wide range of materials from steel, stainless steel, nickel alloys to plastics and ceramics. Even steel products possessing complex surfaces can be completely uniformly heat-coated thanks to modern robotic manipulation applications.Thermal spray steel coating method is considered an advanced method in the plating process that promises to bring a lot of convenience to the manufacturer along with a thick and uniform coating for the product. However, the method will require manufacturers to spend high initial input costs due to technological requirements.Powder steel coating methodPowder coating is a popular coating technology today with the principle of using electromagnetic force to make the paint adhere to the surface of the steel layer. The manufacturer will take advantage of the negative electrical charge on the steel surface, but use a mixture of paint powder with a positive charge to create a strong bond to help the paint layer adhere and spread evenly throughout the surface.It is thanks to this physical principle that the powder coating method will give better results than conventional coating. Powder coating is well known for providing products with a thick and smooth finish, providing a high gloss finish to the product's appearance.Although powder coating brings durability along with highly aesthetic color to the product, it consumes a considerable amount of input costs. The powder coating process requires manufacturers to own spray booths and specialized spray equipment to perform, so this method will not be feasible for small manufacturing businesses.Paint coatingThe last steel coating method mentioned in today's article cannot mention the paint coating process. In order to create a protective coating on the surface of the product, the manufacturer will perform 3 layers of paint including: primer, intermediate coat and top finish paint. Weather conditions will also significantly affect the paint, so the right temperature for the paint to be durable and beautiful is usually between 10 degrees Celsius and 35 degrees Celsius.The implementation of the paint coating method not only helps protect the steel surface from harmful agents from the environment, but also creates an aesthetic appearance with outstanding colors. Although the durability of the coating method will not be better than the other methods, they are highly appreciated in supporting the cost of input materials, this plating method is extremely suitable for most businesses in both small and medium scale.The steel coating method has appeared and become popular for a long time in the manufacturing field because it acts as a protective shield for the steel core. The above article lists the top 5 most popular steel coating methods today along with the advantages and disadvantages of each method.

The purpose of the steel mills assessment is to select the right supplier for the enterprise's requirements. That's important, but many businesses are still wondering what the objective and accurate evaluation criteria are. The following article summarizes the criteria for evaluating steel mills so that you can choose reliable partners.Reputation of steel millsWhen evaluating a steel mills, the reputation of the factory is the first factor and also a decisive factor in deciding whether to cooperate or not. To consider whether the factory is reputable enough, we need to note a few aspects:Clear information: Does the factory really exist? Address, contact method, business license or not?Transparency in cooperation: Does the factory ensure the supply of raw materials and maintain long-term cooperative relationships with partners?Review of legal issues: View legal procedures related to past and current factory contracts; Is the factory's legal compliance guaranteed?Product qualityThis is the most important criterion when any business wants to make a decision about choosing a steel mills. When sourcing products, businesses will proceed to provide criteria for quotes, product quality, materials, durability, aesthetics,... From there, make a detailed assessment and draw the conclusion that the product of this factory is suitable for the needs of the business you are looking for. You should build a form, a tracking sheet in the form of a scale, to comment on all aspects of the quality of goods supplied by the factory.In addition, it is also necessary to consider the damage rate of the goods. Specifying a specific risk level or criterion after the time of importing goods and conducting inventory, based on that ratio to track the quantity, find out if the cause of damaged goods is due to the transportation process or supplier error.Production capacity of steel millsProduction capacity is one of the important criteria for evaluating steel mills. The assessment of the production capacity of the factory will clarify the efficiency of the factory's production activities and its ability to meet the needs of the market. A factory with a large production capacity is equivalent to an abundant labor force and modern machinery and equipment. Besides, production capacity also helps to assess the potential of the mill development. The larger the steel mills production capacity, the larger the mill.Product delivery performanceIn the criteria for evaluating steel mills, it is indispensable to evaluate the factory's product performance. Ensuring the performance of the factory's product supply determines the business plan of the enterprise. Therefore, suppliers need to ensure credibility in the time and quantity of products provided. Below are the factors used to evaluate the product supply performance of steel mills:Order fulfillment time: The time from the beginning of order fulfillment to when the supplier delivers the goods to your business.Reliability of delivery: Ensure the agreed delivery time, sure delivery, the right type of goods, the right quality, and the quantity of goods according to the contract.Information: Information is exchanged throughout the steel mills and your business.Flexibility: The steel mill's ability to adapt its product supply to changing conditions.Production technology of steel millsCurrently, steel mills around the world use three main production technologies, including the basic oxygen furnace (BOF), the electric arc furnace (EAF), and the induction furnace (IF). In which BOF technology accounts for the majority, EAF and IF technologies account for a little and very little. This is also an important criterion that businesses need to pay attention to make objective and accurate assessments of steel mills.The fact that factories use modern production technologies not only brings high-quality products but also contributes to saving energy. Technological improvements and upgrades promise to be outstanding advances in product quality and output.Product price and payment methodProduct prices and payment methods are indispensable criteria in the steel mills evaluation criteria table. This criterion affects the buyer's ability to buy and profit. If there are two suppliers with the same quality and performance of products and services, the one with the cheaper price will bring more profits to the business. Evaluation factors may include:Competition: The price paid should be comparable to that of other competitors. Enterprises should have quotes from many steel mills for comparison and better evaluation.Accuracy and stability: The price on the order and on the invoice should only have a small difference. If there is a change in the price, the supplier should notify customers in advance. Prices also need to be stable over time.Payment transparency: The average time it takes to receive a credit note should be reasonable. The estimated cost should not change significantly from the final invoice. Supplier invoices should be timely and easy to read and understand.Customer serviceCustomer services help businesses in cases of problems such as product errors, missing orders, low-quality products,... Therefore, this is a criterion that cannot be ignored when proceeding with the steel mills assessment.When conducting supplier evaluation, it is necessary to collect opinions on the quality of support, the attitude of the supplier and response time to support requests, the qualifications of the support staff,... Customer service will be evaluated through three timelines: before the transaction, during the transaction, and after the transaction.Thus, the above article has summarized seven criteria for evaluating steel mills. However, to conduct the assessment according to the above seven criteria, enterprises need to have accurate, transparent, and complete information about the factory. I hope this information is useful for you in choosing a reputable and quality steel mills.

Purlins are one of the materials that help support the structural framework, most often below the roof. Purlins carry the roof desk load and are supported by building walls, steel beams, rafters,... Purlins are an indispensable part of every project, so choosing the perfect purlin ensures the safety of the entire building. In this article, AG真人游戏 Steel will share some tips for choosing the most suitable purlins to make the roof frame for the project.1. Choose the appropriate purlin materialPurlins combine with rafters to create a roof frame, combining the support of beam frames, walls or steel beams. When choosing the material of the purlin, importer can consider between black pipe steel, galvanized steel or high-strength steel. Each material has pros and cons in terms of strength and cost, so importers need to assess the building design to choose the most optimal material. However, to ensure the safety of the project, steel purlins must be able to withstand high loads, resist corrosion, rust and be unaffected by environmental factors.2. Choose the ideal type of purlinThis is one of the important factors when deciding which type of purlin for your project. C and Z shaped purlins are the two most popular types, have high applicability and unique characteristics as follows:C purlins are made from black or galvanized steel with a C shape and used in structural framework for factories, houses,... Importers can contact AG真人游戏 Steel for advice on the most suitable dimensions, thickness and length for their specific application.Z purlins are manufactured from hot-rolled, cold-rolled, galvanized steel, shaped like the letter Z, so it is easy to stack and connect through bolted joints. Because of this characteristic, the Z shaped purlin has a higher thickness and durability than the C shaped purlin.3. Install purlins properlyCalculating the distance to install purlins compared to the corrugated iron roof in a reasonable, economical and safe way is important in choosing purlins for the project.Firstly, safety and sustainability are the top criteria, requiring the distance between purlins and corrugated iron roofs to be standard and reasonable. Next, if the purlins are not aligned or installed too far or too close, roofing will cost a lot of time and money. Finally, if the purlin distance is not suitable, it also reduces the building's load-bearing capacity, especially making it difficult to repair and maintain periodically.4. No weld/heat cutWelding or heat cutting methods are not used when installing purlins because high temperatures can affect the durability and strength of the purlins.5. Choose a reputable supplier and manufacturerPurlins are a key part in construction projects, so factories always produce many specifications to meet all customer needs. Importers can also find cheap sources from China, India,... but for some countries with strict regulations on C/O or trade defense measures, this option is not feasible. Meanwhile, Vietnam belongs to the group of countries with a developing economy, so it enjoys many preferential duty rates and import policies to the EU, United States, Australia, Mexico, Malaysia,...Vietnam has crude steel output ranked 13th on the world steel map and the largest in Southeast Asia, ensuring abundant and high-quality supply for customers. Many of Vietnam's largest factories do not receive orders directly from importers but through intermediary support units such as AG真人游戏 Steel.AG真人游戏 Steel provides solutions for importing Vietnamese steel to more than 30 countries around the world, with a network of links with many reputable steel factories and shipping lines to promote the fastest and most optimal delivery process.

Steel melting is a complex process, many stages and requires many advanced technologies to create finished products of outstanding quality, meeting the stiff demands in construction. The process has 3 main steps: iron ore treatment, blast furnace molten iron smelting and impurity treatment to form billets and finished products. In this article, AG真人游戏 Steel will describe in detail the steel melting process to help you better understand the nature of this metal.1. What is iron ore steel melting?The process of making steel from scrap steel is relatively simple because the raw material only needs to go through an electric arc furnace (EAF) or an induction furnace (IF) to smelt into square billets and roll out the final product. Meanwhile, steel made from iron ore has to go through a long process with many different complicated stages. Iron ores are rocks containing metallic minerals that are mined and processed to produce steel. Different types of iron ore contain different proportions of iron, divided into 3 basic types:Magnetite: The chemical formula of this ore is Fe3O4 containing 72.41% iron. In nature, the amount of magnetite iron ore is very rare because they possess the highest iron contentHematite: This is an iron ore with 70% iron content, after magnetite, the chemical formula is Fe2O3. In Greek, hematite ore means blood because of their characteristic red color, easily found in Asia, Australia, and Brazil.Pyrit: The chemical formula is FeS2 containing iron content up to 46.67% with metallic, golden copper color. It is the most common of the sulfide minerals.2. What is the process of making steel from iron ore?Step 1: Iron ore processingIron ore with the main components being iron oxides Fe2O3 and Fe3O4 in raw form, with different contents and sizes, processed, mixed according to the required ratio, combined with coke coal, lime and dolomite to put into the furnace to produce liquid cast iron. The product is an alloy of Fe and C with a Carbon content of more than 1.7%. Carbon is an important element affecting the hardness, ductility and toughness of steel. When %C is in the range of 0.8-1%, the steel has the best strength and hardness, but if the ratio exceeds 1%, they begin to decrease. Therefore, the manufacturer reduces C in cast iron and some other harmful impurities (Cu, Ni, Cr) to less than 0.03%. Liquid cast iron water, after being transferred to an oxygen furnace, helps to melt iron ore and reduce the level of impurities such as sulfur, phosphorus,...Step 2: Create a liquid of molten steelFrom the molten cast iron in stage 1, it will continue to be led to the basic furnace or electric arc furnace to treat impurities and combine some other metals such as manganese, chromium, nickel, aluminum, copper, ... to enhance the technical properties of the steel and create the grade required by the market.Step 3: Roll billet, finished steelWhen step 2 has been completed, the liquid metal is put into casting machine systems to form billets or finished construction steel products such as rebar, coil, hot rolled steel,....There are 3 main types of bar stock, slab and bloom, which are cast in two different states: hot casting and cold casting. For bar stock with cross section of 100x100, 125x125 and 150x150, length 6.9m or 12m  for use as coil and rebar. Slabs are often used to make hot rolled coils, cold rolled coils or V-C-U-H sections, while bloom can completely replace both bar stock and slabs.3. Vietnam's modern steelmaking technologyThanks to the closed steel melting process, advanced technology lines imported directly from G7 countries such as Tenova group, Danieli - the leading corporation in Europe and the world in metallurgical and steel rolling equipment, has turned ore into high quality products without impurities. Products after steel melting have impurities below 0.03%, lower than the standards of many fastidious import markets in the world.The process of smelting steel from ore removes many harmful impurities such as S, P, so the finished steel has strength and longer life expectancy. Steel made from iron ore possesses superior physical and mechanical properties and can be rolled into products with a higher diameter and grade of steel such as D55 construction steel, tensile strength reaching over 600N/m2, suitable for construction projects, bridges, ports, skyscrapers,鈥teelmaking is a complex production process, requiring many modern technologies and lines to ensure product quality and not cause pollution to the environment. Vietnam is one of the countries with the leading steel melting capacity in the world.

ASTM standards are critical in the classification and evaluation of the material, chemical, mechanical and metallurgical properties of products. Currently, there are 12,575 ASTM standards in various fields recognized by the international community. ASTM standard can be seen as an advantage to help iron and steel manufacturers easily access fastidious markets.1. What is ASTM?ASTM (American Society for Testing and Materials) is an international standards organization that researches and publishes technical standards for materials, systems, and services around the world.ASTM was founded in 1898 with its headquarters in West Conshohocken, Pennsylvania and today has 12,575 voluntary consensus ASTM standards operating globally. ASTM set the stage for other standards organizations to come later, such as BSI (1901), IEC (1906), DIN (1917), ANSI (1918), AFNOR (1926) and ISO (1947).2. What is the ASTM standard?ASTM standards are a set of technical standards for materials and products around the world that are agreed and accepted by the international community. ASTM standards are widely used in many areas such as:Iron and steel productsNon-ferrous metal productsAnalytical procedures and methods for metal testingBuildPetroleum products, lubricants and mineral fuelsPaints, aromatic compounds and coating compoundsTextilePlasticsRubberElectronics and insulationEnvironmental and water technologyGeothermal, solar and nuclear energyMedical services and suppliesGeneral equipment and methodsGeneral, chemical and end-use productsThe American Society for Testing and Materials does not require manufacturers to comply with ASTM standards, but in trading, companies may require compliance with certain standards. In particular, the ASTM community currently has 30,000 members from more than 140 countries, so the production of iron and steel meeting ASTM standards contributes to bringing products to the world, successfully approaching fastidious markets.3. Why do ASTM standards matterScientists, engineers, architects or businesses and government agencies rely on ASTM standards to ensure the quality and consistency of materials. While using of these standards is voluntary, they are mandatory when cited in contracts, laws or government regulations.ASTM standards are essential in the classification and evaluation of material, chemistry, coherence and metallurgy properties. Manufacturers can adopt the ASTM standard for proper processing and application procedures. You can refer to the official ASTM to search for more than 12,000 available standards divided into 80 categories in 15 related fields.4. Current popular ASTM standards4.1.

After completing the required steel production process, the factories will package and transport the steel to the importer. This process needs to comply with strict storage and handling standards as it impacts product quality.1. Transporting steel from the factoryOnce the order production process is completed, the method of transporting steel depends on various factors, depending on the customer's requirements, such as:Weight of steelNumber of componentsForm of transportationGeographical distanceWeather conditionsDelivery time鈥herefore, the importer needs to provide detailed transportation requirements and at the same time discuss with the factory to find the most reasonable plan, optimize time and ensure the safety of the package.During transportation, the product is firmly fixed to avoid being moved or bumped causing dents or deformation. Transportation vehicles are also carefully calculated so that no problems occur during travel.2. Preserve steel structuresWhen steel structures are waiting for export, they must be strictly and carefully preserved in warehouses that meet the following basic requirements:- The warehouse has a capacity of 0.5-1T per 1m2 for solid structures and 0.6-0.8T per 1m2 for other light structures. Arrangement of steel components must comply with predetermined procedures.- The warehouse floor must also be flat, dry and able to bear weight. When arranging products, ensure the following factors:+ Use concrete or wooden panels as support for steel structures, arrange them neatly into piles of multiple tiers to optimize space.+ The height of each pile must be less than 1.5m and the distance between two piles must be at least 0.75m, the distance between the edge of the pile and the transport road is less than 2m.- Arrange in a straight and tidy line, products do not come into direct contact with the background, the minimum height between the structures and the background is 20-30 cm- Arrange steel structures according to weight, usage needs and small details should be divided into areas3. Loading and unloading process of steel structuresUnder the ship's holdShore cranes or ship cranes use support tools such as cables and specialized hooks to access the ship's deck area to load cargo. Workers attach specialized hooks to both ends of the packages and stack the appropriate number of packages based on the weight and lifting capacity of the crane. The crane stops at a height of about 2 meters to perform safety checks before continuing to the required position. After the goods leave the hatch, workers in the ship's hold can install new packages. The principles, technical requirements and labor safety that need to be noted are as follows:Goods are taken from top to bottom, do not take one side as this will cause the package to be unbalancedShaped steel goods or long heavy structures need to use sharp cables or crowbars to lift the goods when threading the cablesOn the wharfWhen the goods are brought to the unloading position by the crane, workers use a landing hook to adjust the position of the package and let it drop gently and safely. Steel structures are transported by forklifts to the yard or unloaded onto transport vehicles as required. For the process of loading and unloading goods on the wharf, it is necessary to meet the following techniques:Goods must be padded in a stable and secure manner before the cable hook can be removed from the packageWorkers keep a safe distance from packages during the loading and unloading processOn yards and warehousesForklifts stack goods into piles under the guidance of the manager in charge. Goods are arranged in a certain order, ensuring safety requirements for height, size, and distance. The maximum height of each pile is 1.5m, the distance between piles is 5m, fixed with pads to avoid rolling and falling.4.

In building structures recently, the G550 Galvalume Steel Coil suddenly stands out as a useful solution for contractors thanks to its outstanding durability as well as meeting all strict quality standards, contributing to creating a durable structure over the years.1. Origin of G550 Galvalume Steel CoilGalvanized aluminum zinc alloy was first introduced to the public in 1972 with the trade name Galvalume. This is considered as a new improved version formed from galvanized steel sheet through hot-dip galvanizing with the proportions of 55% Aluminum, 43.5% Zinc and 1.5% Silicon.The introduction of Galvalume has been well received from the public, typically after 7 years since its launch, Galvalume has reached the 1 million tons of finished products. Although Galvalume was so popular in the steel industry at that time, until 1990 that the product first appeared in the Vietnamese market. Since 2008, when Vietnam joined the WTO and its economy is thriving, it has led to a series of construction projects being invested more. Contractors have gradually become interested in Galvalume in applying to make roof structures and make up formed purlin frames because Galvalume brings the outstanding advantage including good heat tolerance along with superior oxidation resistance than other products.Currently, Galvalume has been developed and expanded according to many different technical standards, the most popular standards are  from Japan, USA, Europe and Australia. The Australian standard is impressive as a typical standard for steels possessing high hardness and resistance when its Elongation percentage is only 2% - the lowest index when comparing similarity Tensile value among the other three criteria. The specific product which has amazing features is Galvalume Steel Coil G550.2. The technical specifications and signsGalvalume Steel Coil G550 is manufactured according to Australian standards to meet the constitutions and the load level of pressure in steel on Yield Strength, Tensile and % Elongation.G550 has a minimum yield strength of 550 N/mm2, indicating  the remarkable resistance when it can take a huge force of 550 Newtons, equivalent to 55 kg per mm2 to make the product is deformed. In addition, the product also has a Tensile of 550 N/mm2 and the index is not much different from the Yield Strength. Therefore, it can be said that the Galvalume Steel Coil G550 possesses almost absolute hardness and brittleness. This figure contributes to increasing the rigidity of the product in particular and the solidity of the construction in general, minimizing warped or dented products at the construction site.Currently, Galvalume Steel Coil G550 has 2 main colors including: Blue (AZ150), Bronze (AZ200). Depending on the color, the manufacturer will cover a zinc coating with different thicknesses, specifically 150g/mm2 for the navy blue type and 200g/mm2 for the copper color type. Possessing a zinc coating thickness of over 150, not only helps the product own a beautiful glossy surface from the zinc properties, but also enhances the excellent oxidation resistance, limiting the absorption of heat from the sun of aluminum.3. Outstanding advantages of G550 and common applicationsBecause of the special combination of aluminum and zinc, the product has improved its resistance to corrosion and oxidation, while adding excellent heat and fire resistance to help G550 Galvalume Steel Coil withstand local wind and rain loads, it's extremely suitable for roofing applications in construction.In the past, people often used black iron to make parts in the roof structure frame, but the types of black iron are very susceptible to rust, so the users have to check and maintain it every year. Since galvalume steel was introduced, it has shown 4 times longer life than ordinary black or galvanized steel, so the problem of ensuring sustainability has been thoroughly solved. Specifically, the G550 Galvalume Steel Coil series is frequently used by contractors in making purlins and bridges for tiled structural frames. Under the effect of the zinc coating, the surface of the structural frame will always maintain a shiny condition, bringing a good appearance to the building, the coating also helps to limit peeling and scratches, maintaining the appearance which is bright and new to the roof over time.4.

In the future, "green steel" can completely replace conventional steel, but this is a long-term game and costs a lot of money. So let's find out with AG真人游戏 Steel what green steel is and why it is so important.Steelmaking is an industry that pollutes the enviromentsAmong heavy industries, steel production, although it plays the most important role in the world economy, is also the industry that emits the most CO2. According to a Bloomberg NEF report, the steel industry accounts for about 8%鈥�9% of the world's total carbon emissions. Currently, blast furnace steel production accounts for 70%鈥�80% of steel making technology being applied worldwide; the remaining few are applying green steel making methods. No matter how steel is smelted, the industry is still emitting many harmful gasses that affect people and the environment.In the steel manufacturing industry, normally to produce 1 ton of steel, 10,000 m3 of exhaust gas and 100 kg of dust must be released into the environment, along with many other harmful emissions, which contain many heavy metals and metal oxides such as CO, CO2, SO2, and NO2.Green Steel - The future of the steel industryGreen steel is a steel product that is manufactured using environmentally friendly technology but is not really different from conventional steel. The steel produced relies heavily on the use of green hydrogen, a product of renewable electricity, rather than burning coke and iron ore like conventional steel. A process with great promise for the steel industry, as the carbon and hydrogen decarbonization routes will release water, thereby reducing the amount of CO2 in the steel industry by up to 90%.Of these, hydrogen used in green steel can be generated in many ways, such as through electricity, which uses an electric current that splits water into oxygen and hydrogen. If the electricity comes from wind or solar energy, then the hydroelectric output is called green hydrogen or renewable hydrogen.The Earth is increasingly warming due to the impact of the greenhouse effect, which is the main cause of direct impacts on human life. In the context of countries' governments taking measures to improve the environment, green steel production is a method that is both vital for the steel industry and contributes to limiting global climate warming.Is green steel expensive?Green steel will be more expensive than conventional steel because it uses more complex and expensive production methods. In 2018, SSAB published an estimate that green steel prices were about 20%鈥�30% more expensive than conventional steel prices at that time. Therefore, if the production cost is higher, the price of green steel in the future may become more and more expensive. As a result, the price of products made from steel will also increase.With the benefits it brings, green steel will be the main source of steel and the future of the steel industry in the near future. Hopefully, with the use of this renewable energy source, the steel industry will reduce its impact on nature and the environment.
