PPGI Introduction:
The galvanized color-coated coil is to prevent the surface of the steel plate from corroding to prolong its service life, and a layer of metal zinc is plated on the surface of the steel plate. According to production and processing methods, it can be divided into 1) Hot dip galvanized steel coil. The sheet is in the molten zinc bath with a layer of zinc flakes attached to its surface. At present, the continuous galvanizing process is mainly used, that is, the steel plate is continuously rolled in the melt galvanizing tank made of galvanized steel plate; (2) Alloying of galvanized steel. This kind of steel coil is made by hot dip method, but after grooving, it is heated to a temperature of about 500 ℃ immediately to form a zinc-iron alloy film. This galvanized sheet has good coating and weldability; The galvanized color-coated coil is to prevent the surface of the steel plate from corroding to prolong its service life, and a layer of metal zinc is plated on the surface of the steel plate.
