Galvanized steel coil is a steel coil that has been treated with a galvanizing process. It has anti-rust and corrosion resistance properties and is widely used in construction, home appliances, automobiles and other industries.

Color coated steel coils (pre-coated color coated steel coils) are widely used in construction, home appliances, transportation and other fields due to their corrosion resistance, rich colors, light weight and durability.

Galvalume coil (also known as galvalume steel sheet, common grades such as AZ150, AZ185, etc.) is a metal material with aluminum-zinc alloy (usually composed of 55% aluminum, 43.4% zinc, 1.6% silicon) plated on the surface of steel sheet, which has both the corrosion resistance of aluminum and the cathodic protection of zinc. It has a wide range of applications, especially in harsh environments.

The aluminum-zinc color-coated steel coil (i.e., composite steel with aluminum-zinc substrate + color coating) combines the corrosion resistance of aluminum-zinc steel plate with the beauty and weather resistance of color coating, and is widely used in fields with high requirements for corrosion protection and decoration.
