1) Surface state: The surface state of galvanized sheet varies depending on the coating method, such as regular zinc spangle, fine/small zinc spangle, flat zinc spangle, zero zinc spangle, phosphating surfaces, etc. 2) Galvanized sheets should have a good appearance and should not have defects that are harmful to the use of the product, such …
Color coated plates are prone to cracking before welding. We should first understand the cause of the crack in order to identify the cause and avoid accidents. The zinc layer near the groove of the color coated plate oxidizes (forms ZnO) and evaporates under the action of arc heat, emitting white smoke and steam, making …
