DX52D/SGCD1 Galvanized Sheet Description
DX52D galvanized sheet is a galvanized steel sheet material with a thin and uniform zinc layer on its surface. This zinc layer can effectively protect the steel sheet from corrosion and oxidation. In addition, DX52D galvanized sheet also has good processing performance and welding performance, and can meet various building processing and construction needs. DX52D galvanized sheet 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.
