Introduction to Galvanized and Galvalume Steel Sheets/Coils
Galvanized and Galvalume steel sheets and coils are essential materials in various industries due to their excellent resistance to corrosion and versatile applications. These materials, distinguished by their unique coating processes, provide enhanced durability and performance, making them suitable for a wide range of uses.
Classification of Galvanized/Galvalume Steel Sheets/Coils
According to the raw materials and processing methods, steel sheets and coils can be divided into the following categories:
Galvanized Coil/Sheet
Galvalume Coil/Sheet
Prepainted Coil/Sheet
Galvanized Coil/Sheet
Galvanized steel is a hot-dipped coated metal that provides better resistance to corrosive environments. This steel is coated with a layer of zinc, making it difficult for rust bacteria to corrode. It is widely used in industries such as electric power, transportation, automobile, construction, and chemical.
Function of Galvanized Steel Sheets/Coils
Galvanized coil is mainly used in:
Construction: Manufacturing anti-corrosion industrial-grade civil building panels and roof grilles.
Light Industry: Manufacturing corrosion-resistant parts for cars.
Agriculture, Forestry, and Fishery: Grain storage and transportation, frozen processing utensils for meat and aquatic products.
Commerce: Storage and transportation of materials, packaging utensils.
Galvalume Coil/Sheet
Galvalume steel refers to 55% Al-Zn coated steel products, also known as aluzinc steel. The Galvalume coating aims to protect steel from oxidation. With aluminum protection, it resists rusting and corrosion more effectively. GL steel is well suited for roofing, siding applications, automotive, home appliances, and furniture.
Function of Galvalume Steel Sheets/Coils
Aluminum-zinc coils are used in:
Construction: Roofs, walls, garages, soundproof walls, pipes, and modular houses.
Automotive Industry: Mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes.
Home Appliances: Refrigerator back panels, gas stoves, air conditioners, electronic microwave ovens, LCD frames.
Agriculture: Pig houses, chicken houses, granaries, greenhouse pipes.
Others: Heat insulation protection covers, heat exchangers, dryers, water warmers.
Prepainted Coil/Sheet
Prepainted Steel is obtained by painting zinc-coated or Al-Zn coated steel products. This type of steel is popular for its abundant color and texture options, superior adhesion, reliable surface consistency, and efficient production process. Prepainted steel sheets are used for roofs, doorways, interiors, insulation, appliances, automotive, and solar reflective paneling.
