galvanized steel coil
Hot galvanizing (also called hot dip galvanizing) is a kind of effective metallic anti-corrosion mode and mainly applied to metallic structure facilities in various industries. A steel piece subjected to rust removal is dipped into melted zinc at the temperature of nearly 500℃, and a zinc layer is coated on the surface of the steel structure piece, so that the aim of resisting corrosion is achieved. The flow of the hot galvanizing: acid cleaning of finished products—water washing—adding of auxiliary plating solution—drying—rack plating—cooling—medicinal chemistry—cleaning—grinding—finishing of hot galvanizing. The hot dip galvanizing process is developed from old hot platig methods, and it has a history of over 140 years since its application to the industry of France in 1836. However, the hot dip galvanizing industry has been greatly developed in recent three decades with the quick development of cold-strip steel.
