Galvanized Steel Coils refers to steel sheets coated with zinc through a hot-dip galvanizing process. The zinc coating protects the steel from corrosion and provides a durable layer of protection. The size of crystallites in galvanized coating is a visible and aesthetic feature, known as spangle. Galvanizing is one of the most effective and ecnomical methods for protecting bare steel from corrosive environments. It has wide usage, like making pipes, cutting sheets, making small tools, making corrugated sheets, making container, making fences, glass curtain walls, aluminum curtain walls as columns and stress materials, or for outdoor telecommunicatins towers, highways, other open-air construction steel and etc.. For the surfaces, there is zero spangle, regular spangle. It can be produced as customers' requirements. According to different usage, there are many techniques to satisfy the demand. For example, oiled, chromated and skin passed are the normal requirements.
