DX51D Galvanized Steel Sheet is a steel plate with a layer of zinc on its surface. Galvanizing is often used as an economical and effective rust prevention method. About half of the world’s zinc production is used in this process. A galvanized steel plate is to prevent corrosion of the steel plate surface to extend its service life, coated with a layer of metal zinc on the surface of the steel plate(SPCC), This coated zinc steel plate is called a galvanized sheet. the surface state: galvanized sheet due to different treatment methods in the plating process, the surface state is also different, such as ordinary zinc flower, fine zinc flower, flat zinc flower, no zinc flower, and phosphating treatment of the surface. The German standard also provides for surface grades. The galvanized sheet should have a good appearance, and no harmful defects to the use of the product, such as no plating, holes, rupture, and scum, more than plating thickness, abrasion, chromic acid dirt, white rust, etc. Foreign standards are not very clear on the specific appearance defects. When ordering, the specific defects should be specified in the contract.
DX51D galvanized steel sheet surface:
(1) Surface condition: Due to different treatment methods during the electroplating process, the surface conditions of galvanized sheets are also different, such as ordinary zinc flowers, fine zinc flowers, flat zinc flowers, no zinc flowers, and surface phosphating treatment. German standards also specify surface classes.
(2) Galvanized sheets should have a good appearance and no defects harmful to product use, such as no coating, holes, cracks and dross, excess coating thickness, wear, chromic acid dirt, white rust, etc. Foreign standards are not very clear about specific appearance defects. When ordering, specific defects should be indicated in the contract.
