Aluminum-zinc alloy-coated steel is a material that plays an indispensable role in many fields of construction and industry

What are aluminum-zinc coated sheets?

Aluminum-zinc alloy-coated sheets are a type of rolled steel covered with two surface layers of an alloy consisting of 55% aluminum, 43.5% zinc, and 1.5% silicon, through a continuous hot-dip coating process controlled by the NOF furnace temperature to ensure appropriate mechanical properties for various applications.

SSSC aluminum-zinc alloy-coated sheets are produced according to technological standards on continuous hot-dip galvanizing lines (using Tenova’s modern NOF furnace technology from Italy), offering high corrosion resistance in natural environments. The surface of the SSSC cold-rolled product is smooth and shiny, suitable for applications such as roofing panels, crafts, and many other uses. This product meets industry standards such as Japanese standard JIS G3321 and American standard ASTM A792/A792M.

Applications of aluminum-zinc alloy coated sheets

Aluminum-zinc alloy-coated sheets are versatile and flexible materials with numerous applications across various fields. Here are some practical uses of this material in construction and industry:

• Decking: Aluminum-zinc coated sheets are widely used in decking, especially in areas with harsh environmental conditions like coastal regions or high humidity areas. Their corrosion resistance and durability make them an ideal choice for outdoor applications.
• HVAC Ducts: In the HVAC (Heating, Ventilation, and Air Conditioning) industry, aluminum-zinc coated sheets are commonly used for air ducts and exhaust systems. This material not only offers good corrosion resistance but also has heat resistance and high durability, making it suitable for tropical and harsh terrain environments.
• Structural Steel Purlins: In construction, aluminum-zinc coated sheets are often used as structural materials for purlins, columns, and steel frames. Their strength, corrosion resistance, and flexibility make them a popular choice for building warehouses, factories, or high-rise buildings.
• Home Appliances: Aluminum-zinc coated sheets are also used in producing components and parts for home appliances such as washing machines, refrigerators, and air conditioners. Their durability and corrosion resistance make them suitable for use in humid and wet environments.
• Interior Decoration Products: With a smooth surface and design flexibility, aluminum-zinc coated sheets are used in manufacturing interior decoration products such as doors, railings, and wall panels. Their variety in colors and patterns, combined with corrosion resistance, makes them a popular choice for decorating living and working spaces.
• Other Construction Products: Besides the mentioned applications, aluminum-zinc coated sheets are used in various other construction products such as roof covers, water pipes, and drainage systems. Their durability and corrosion resistance help extend the lifespan and reduce maintenance costs for construction projects.
