🏗️ Product Description

Hot Dipped Galvalume Steel Sheet in Coil

Hot dipped galvanized steel coil are processed by continuous hot-dip galvanizing from cold-rolled steel coil. Zinc coating on both sides can effectively prevent corrosion and rust, and increase the service life of steel plate.

The main characteristics include good processing performance, strong corrosion resistance, high heat resistance, and perfect mechanical properties, which are beneficial for infrastructure and construction.
