Product Description
The error of zinc layer is about plus or minus 10g.The zinc layer has uniform thickness and strong adhesion. No peeling and good corrosion resistance.The zinc layer has uniform thickness and strong adhesion. Processing and forming without peeling, corrosion resistance is very good, after 20 years without corrosion, the surface is very smooth and clean, zinc flower is symmetrical, beautiful.
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.
