Good quality galvanized steel sheet grades 1220 gi galvanized steel rolls and sheets
Hot galvanized sheet in which a sheet of steel is dipped into a molten zinc bath so that a layer of zinc is adhered to its surface. The main use of continuous galvanizing process production, that is, into a roll of steel plate continuous dip in the melting of zinc plating tank made of galvanized steel plate; Alloyed galvanized steel sheet. This steel plate is also made by hot dip, but immediately after the trough, it is heated to about 500℃, so that it generates an alloy film of zinc and iron. This galvanized sheet has good coating adhesion and weldability.
Hot galvanized sheet is mainly used in construction, household appliances, automobiles, machinery, electronics, light industry and other industries.
The common steel types of hot galvanized sheet are: general commodity coil (CQ), structural galvanized sheet (HSLA), stamping galvanized sheet (DQ) deep drawing hot galvanized sheet (DDQ), baking hardening hot galvanized sheet (BH), dual phase steel (DP), TRIP steel (phase change induced plastic steel) and so on.
Galvanized annealing furnace has three kinds: vertical annealing furnace, horizontal annealing furnace and vertical horizontal annealing furnace.
Usually there are two cooling methods of hot galvanized sheet cooling tower: air cooling and water cooling.

Normal spangle
Through addition of certain heavy metal element into molten zinc bath, regular spangle pattern is produced on Hot-dip zinc-coated steel sheet.

Production Process of Galvanized Steel Coil
Galvanized steel coil is to immerse a thin steel plate in molten zinc, so that a layer of zinc is attached to the surface. It is
an effective anti-corrosion method and can provide a long service life of metal materials.
