At Wanzhi Steel, we generally use scorching-dip galvanized steel sheets as the base metal. Using the protection with the zinc layer and natural coating, its provider existence is for a longer time than Aluzinc steel coil that of the hot-dip galvanized sheet. The maximum zinc layer accessible is 275 g/㎡.
The selection of substrate is vital mainly because it need to have the necessary mechanical Houses and corrosion resistance with the meant end use.
The organization now shares numerous grades, widths and requirements of pre-painted steel, which may be custom made painted and processed In line with buyer specs.
When a coating is subjected to heat, humidity or a combination of both, You might even see a localized loss of adhesion as well as coating lifting from your fundamental floor.
