DETAIL INFORMATION 

Color steel coil

1. Hot-dip galvanizing is a protection method for steel work pieces against atmospheric corrosion and widely used in metal structure facilities. Galvanized steel coils are made of full hard steel coil through UEC hot dip galvanizing process. After pretreatment and annealing treatment, the dusted steel material submerged into melted zinc solution which is about 500°C hot to attach zinc coating on the steel as corrosion protection. Then after finishing and pulling-straightening treatment, the galvanized steel coils or sheets are finally completed.

2. Characteristics: a) Galvanized steel coils are low –cost: Zinc coating is cheaper than other coatings. b) Lasting and durable : The zinc coating is attached by chemical reaction to become the surface of the steel sheet, therefore , the coating lasts for a long time .Generally, standard zinc coating (Z60—Z150)can last for 50 years without any repair while in coastal areas lasting 20 years. C) Galvanized steel coils are in strong toughness :The zinc coating owns special metallurgical structure which bears mechanical damages in delivery and application. d) Galvanized steel coils are in good protection: The steel materials are totally submerged into the alloy and galvanized in every place; even the depressions, concaves, and sharp corners of the steel materials could be galvanized and protected. e) Galvanized steel coils are convenient: Galvanizing is easier and more convenient than other coating application. Besides, applied in construction, there is no need to paint once the galvanized steel coils & sheets are installed in construction sites.
