PRODUCT DESCRIPTION

DX51D Z275 Zinc Coated Cold Rolled Hot Dipped Galvanized Steel Coil Factory Description

DX51D Z275 galvanized coil is a galvanized steel material with a thick and uniform zinc layer on its surface. This zinc layer can effectively protect the steel coil from corrosion and oxidation. In addition, DX51D Z275 galvanized coil also has good processing performance and welding performance, and can meet various building processing and construction needs. DX51D Z275 galvanized coil can be used for various welding operations. Since there is a layer of galvanized layer on its surface, you need to pay attention to the protection of the galvanized layer during welding to avoid welding defects.

Scope of Application

Galvanizing products are widely used in industry, agriculture, animal husbandry and fishery, energy, transportation, chemical industry, light industry, home appliances, construction, communications, national defense and other fields.
