Galvanized corrugated sheet is a profiled sheet made of galvanized sheets that are rolled and cold-bent into various wave shapes. It is a metal material, the surface is coated with zinc, which has good anti-rust, corrosion resistance, and durability. Widely used in construction, manufacturing, automobile, aviation and other fields.

Galvanized corrugated sheet is mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. The construction industry is mainly used for the manufacture of anti-corrosion industrial and civil building roof panels, roof grids, etc. Light industry uses it to make home appliance casings, civil chimneys, kitchen utensils and so on

Galvanized coil, dip a thin steel plate into a melted zinc tank, so that the surface adhered to a layer of zinc sheet steel. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the plating tank with melted zinc to make galvanized steel plate. Alloyed galvanized steel plate. The steel plate is also made by hot dipping, but immediately after it is out of the groove, it is heated to about 500℃ to create an alloy coating of zinc and iron. This galvanized coil has good coating tightness and weldability

1) Surface state: The galvanized sheet has different surface states due to different treatment methods in the coating process, such as common zinc flower, fine zinc flower, flat zinc flower, zinc flower-free and phosphatized surface, etc. German standards also stipulate that there are surface grades.
(2) Galvanized products shall have a good appearance, and shall not have defects harmful to product use, such as no plating, holes, cracks, scum, excess plating thickness, scratches, chromic acid dirt, white rust, etc. Foreign standards are not very clear about specific appearance defects. When ordering, some specific defects should be listed in the contract.

Galvanized steel plate is to prevent corrosion on the surface of the steel plate to prolong its service life, coated with a layer of metal zinc on the surface of the steel plate, the zinc coated steel plate is called galvanized plate.
