G550/S550 Hot Dip Galvanized Steel Coil , gi Coil Price G60 G90 Z180 Z275 From China Factory

Short Description:

Hot dipped galvanized steel coils is mainly produced by continuous galvanizing process, that is, continuous immersion of rolled steel sheets in a galvanized pool with molten zinc to make galvanized steel coils.The surface condition of galvanized coils is different due to the different treatment methods in the coating process, such as ordinary spangle, fine spangle, big spangle, zinc-free spangle (zero spangle), and phosphated surface.In some countries, the method of expressing the thickness of the zinc layer of galvanized steel coil is Z40g Z60g Z80g Z90g Z120g Z180g Z275g, some countries express it as G30 G40 G60 G90.Galvanized steel coils are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries.
