Galvanized Steel Coils Sheets


High-precision hot-dip galvanized sheet (coil) is continuously produced by mature hot-dip galvanizing process with high-quality low-carbon cold-rolled substrate. The steel plate is immersed in molten zinc liquid to form a dense metallic zinc layer, which forms metallurgical bonding with the steel substrate with firm adhesion and is not easy to fall off. The plate surface is processed by precise leveling with strictly controlled dimensional tolerance. It can be cut into various fixed-size flat plates according to customer requirements or supplied in coil form. As a widely used basic anti-corrosion metal raw material in steel structure, electromechanical and photovoltaic industries, it supports custom processing of non-standard small sheets such as 620×465.

Main Features

  1. Uniform and dense zinc coating delivers excellent corrosion resistance and can resist humid, rainy and atmospheric corrosion in outdoor environment for a long time;
  1. The plate is flat and smooth with high dimensional accuracy and good performance for stamping, bending and forming;
  1. Spangled and zero-spangled surface are optional for direct application or subsequent spraying and coating treatment;
  1. Raw coils can be flexibly slit and cut to length, supporting customization of various non-standard small sheets such as 620×465.
