Besides aluminum-coated coils, galvanized steel coils are also widely used materials in many fields. Have you fully understood the characteristics, pros and cons of galvanized steel coils and how the galvanizing process takes place? 1. What is Galvanized Steel Coil?Galvanized steel coil is a material that is coated with an outer layer of zinc to protect the product from the effects of the surrounding environment such as temperature, humidity, air,... Thereby, limiting the possibility of rust , anti-oxidation and corrosion to increase strength and life span of coils.2. Methods of galvanizing steelCurrently, there are 3 most commonly used galvanizing methods: cold galvanizing, hot -dipping galvanizing and electro galvanizing.2.1. Cold galvanizing methodCold galvanizing is a method of coating a layer of liquid zinc on the surface of the product at room temperature and then putting it through a cold galvanizing process. Here, the mill uses compressed air to blow a liquid solution to form a beam of zinc particles that shoots onto the metal surface. In the solution, there are additives to help the coating adhere firmly to the metal surface and harden in a short time. Cold galvanizing technology helps to improve the corrosion resistance of metal, so it is the best solution for galvanizing metal materials on site.2.2 Hot dip galvanizing methodHot-dip galvanizing is the most popular coating technology today, capable of effectively protecting coils from the effects of the environment. This process starts from dipping the product into a molten solution to form a strong, non-flaking base and a smooth, highly aesthetic product surface.2.3. Electrolytic galvanizing methodElectrolytic galvanizing is a method of electrocoating that forms a thin layer of metal on the surface of coil for the purpose of preventing metal corrosion, increasing electrical conductivity, size and hardness. In fact, the electrolytic galvanizing method is used for steel products such as water pipes, railways, outdoor equipment, bearing equipment, machine parts,...3. Standard galvanizing processThere are 3 methods of galvanizing steel, but hot-dip galvanizing is still the most commonly used method in Vietnamese factories with the following standard implementation process:Step 1: Metal surface treatmentSteel made from iron ore or recycled steel also contains many impurities, dirt and oil that reduce the ability to adhere to the coating layer. Therefore, the material needs to be soaked in the degreasing solution for 10 - 15 minutes and transferred to a solution of hydrogen chloride concentration of 8 - 15% to remove rust.Step 2: Embed Soldering fluxAfter the steel is cleaned, it has dipped into the flux for about 3 - 20 seconds at normal temperature to completely remove the oxide and iron ions on the surface of the product. This is also the step that creates a coating that protects the steel from oxidation.Step 3: Hot dipped galvanizedSteel will be completely immersed in the galvanizing bath at the melting temperature (454 - 465 degrees Celsius) to create a layer of zinc coating on the surface. After completing the hot dipping process, performing slag scraping on the surface combined with vibration to remove excess zinc, the product will be coated with a layer of chromate to protect the surface comprehensively.Step 4: Cool down and check qualityIn order for the surface of the galvanized steel coil to be bright and beautiful, the product is cooled by an overflow bath. Experts observe and calculate the thickness of the coating by using specialized gauges to ensure that the finished product meets the specifications and requirements of the customer.4. Pros and cons of galvanized steel coilLow costThe production cost of galvanized steel coil is much lower than other surface protection coating methods, so it is the first choice for large-scale construction projects.DurableThe zinc coating protects the coil from rust, environmental corrosion and chemical reactions of the inner steel components. According to research, galvanized steel coil has high durability, using life up to 50 years in ideal conditions and from 20-25 years in harsh conditions such as industrial zones, coastal areas,...AestheticsCompared with conventional steel products, galvanized steel coils have a shiny, smooth surface and are easily coated with high-grade color paint to increase aesthetics.Reduce maintenance costsGalvanized steel products have high durability, long service life, so it does not cost a lot of maintenance and regular maintenance during use.5. Application of galvanized steelGalvanized steel possesses high strength, good bearing capacity, is a familiar material in popular applications including:Deck floor application to replace floor formworkVentilation ducts for apartments, high-rise buildings, shopping centers, factories, etc.Producing purlinProducing all kinds of steel pipes, water supply and drainage pipes, oil and gas pipelines, vehicle accessories,...Producing household appliances, furniture…6. Vietnam's export strength of galvanized steel coilWith investment in infrastructure, modern equipment and strictly selected raw materials, Vietnam galvanized steel coil mills provide product lines with thicknesses from 1.5 to 3.0mm, coating degree Z275 - Z350, strength up to G450.FDI projects especially favor these types of galvanized steel because of their durability. high quality and good resistance to environmental conditions, so the life of the works can be up to 50 years.In addition, galvanized steel coils also meet many international standards such as JIS G3302 of Japan, BS EN 10346 of Europe, AS 1397, ASTM A792 of the United States, conquering many difficult export markets such as the EU, the United States, Korea and Southeast Asia,...

Galvalume is considered a special imported product because the process of finding out information about the item is always complicated. Galvalume steel coil specifications always come with a series of dense data in terms of width, hardness, and thickness that importers need to learn carefully before conducting a transaction.Technical Galvalume Steel Coil SpecificationsThe technical specifications are the evidence demonstrating the strength, toughness and mechanical properties of products. If you are an importer and do not know the basic specifications below before proceeding to trade the item, it is very easy to meet the situation of receiving the finished product not as expected.ThicknessThe thickness is one of the important galvalume steel coils specifications in the information description table. The thickness will certainly affect the selling price, depending on a coil of steel thickness or thin that the factory will calculate a suitable price for the buyer. Sometimes importers require oversized thicknesses, which will make it difficult to find source because not all factories can meet the special requirement of thickness in production.Currently, for Galvalume coils, the ideal thickness is usually in the range of 0.25 to 1.2 mm. The reason why is called the ideal thickness because this is the thickness range that most factories can produce and it is often widely applied in many fields.Coating thickness symbolGalvalume steel coil has 3 layers including base steel layer, aluminum zinc coating layer and color coating layer. Therefore, when viewing coating symbols, importers need to keep in mind a few definitions. There are 3 common coating thickness symbols in galvalume steel coils specifications used by steel manufacturers including BMT, TCT and APT.BMT: reflects the thickness of the base steel layer, which is the inner steel core that has not undergone aluminum galvanizing processes. Therefore, if the galvalume coil is printed with BMT, the importer should understand this as the thickness symbol of the cold rolled coil.TCT: The full name of TCT is Total Coating Thickness, which means that the thickness of the product will now include the base steel layer along with the galvanized layer.APT: APT is the only symbol for prepainted galvalume steel coil products because APT stands for After Painting Thickness, the thickness of the steel product after color plating.Width Besides the thickness, the width gauge size also plays an important role among galvalume steel coils specifications, the manufacturer will rely on these two parameters to calculate the weight of the steel coil. The common formula for calculating the weight of coiled steel applied by many factories today ism (kg) = T (mm) x W (mm) x L (mm) x 7.85Where T is the symbol for the steel thickness, W represents the width and L is the length of the coil. The number 7.85 is the density of iron in mathematics.Grade (Hardness)If thickness was a reflection of the steel's appearance, then hardness would be a measure of the strength for galvalume steel coils. High hardness means that the strength of steel is extremely good and it also shows durability. However, higher hardness also makes the steel become more difficult to handle in machining and design applications. People usually will rely on 3 criteria to evaluate the hardness of steel including: Tensile, Yield Strength and Elongation.Yield StrengthThe manufacturer will put the steel in a specialized machine and start pulling at the 2 heads of the steel, at a certain force when the steel begins to deform, the manufacturer will rely on that to record the Yield Strength of the product.Tensile If Yield Strength reflects the time to deform of steel, then Tensile will be the proof of the maximum strength of a steel product. When the tension between the two heads reaches a large enough to make the steel break at this point, it is called Tensile. Currently, the unit of measure applied to both Yield Strength and Tensile is MPA (N/m2).ElongationElongation is a measure of the distance between the beginning deformed position to the point of failure, it is calculated based on the ratio between Yield Strength and Tensile. If the percentage of Elon is large, it shows that the steel is ductile and easy to form up. Whereas the percentage of Elon is low, it means that the steel is hard and brittle, the steel structure is extremely solid but it will interfere with shaping.In addition, the steel hardness parameters shown on the information table are usually calculated based on the minimum force impact. More specifically, if the Yield Strength parameter is G300, when testing the steel standard, the manufacturer will have to use a minimum force of 300 Newtons to deform the steel.Color IDOne color tone will have many different color shades, so learning the color code before implementing trade will help importers avoid the risk of receiving wrong colors. During the negotiation process between the two parties, the manufacturer will often send to customers a RAL color system with certain symbols on them. When the customer reports the color code, the manufacturer will base on the customer's color requirements to mix the paint color.Commodity classification in galvalume steel coil specificationHS CodeHS is a commodity classification code that is applied to all countries, so when conducting commercial transactions between two countries, understanding the HS Code is the necessary action in determining the category of goods.Conventional iron and steel products refer to the first 2 digits as 72, the following numbers will classify in more detail the width as well as the thickness of the steel coil. The most common HS Code of galvalume coils today is denoted by 8 digits 72107013.Country of origin & Brand NameOne of the last galvalume steel coil specifications that importers need to pay attention to is information about the origin of the product. Possessing a certificate of origin will make the goods easier to clear and the importer can rely on it to distinguish whether it is an authentic product or a floating product on the market.Find out the good partner in removing barriers when importing Galvalume steel The expanding global economy as a trend has led to the development of cross-border commercial cooperation relationships.

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.
