PRODUCT DESCRIPTION

Hot Dipped Zinc Coated Steel S350gd G550 Z20 Galvanized Steel Plate Sheet Description

Z20 galvanized sheet is a kind of galvanized steel sheet. The galvanized layer has good corrosion resistance and can effectively protect the steel sheet from corrosion. Besides, Z20 galvanized sheets have good processing performance and can be used for shearing, bending, welding, drilling and other processing operations. At the same time, the galvanized layer can also increase the hardness and strength of the steel plate, making it more wear-resistant. Its excellent corrosion resistance and processing properties make it widely used in the construction industry. In addition, galvanized steel sheets can also be used to make lightweight steel structures, brackets and other components, effectively improving the stability and service life of buildings.


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.
