Zinc 40g/m2 regular spangle galvanized coils GI coils from China mill For galvanized steel coils, the steel sheet is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.

This product is produced by the manufacturer in coils on the continuous production line, so it is also called prepainted steel coil. It not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials.

The painting quality is ore well-distributed, more stable and more ideal than painting directly on the single metal structural surface. Prepainted Galvanized Steel Coils has good decorative, forming property, anti-corrossion and strong adhesive. The color can last for long time. As Prepainted Galvanized Steel Coils can take place of wood, prossesses good economic efforts like fast construction, energy saving, anti pollution, it has become an ideal construction material nowadays.
