Galvanized Steel Coil SGCC DX51D Z60 Z80 Z100 Z120 Z275 Hot Dipped GI Zinc Coated Steel Coil
Product Description
Galvanized Steel Coil SGCC DX51D Z60 Z80 Z100 Z120 Z275 | Hot Dipped GI Zinc Coated Steel Coil for Building Material
Product Overview
Our galvanized steel coil is produced through the continuous hot-dip galvanizing process, in which cold-rolled or hot-rolled steel strip is immersed in a molten zinc bath at approximately 450°C. This creates a metallurgically bonded zinc coating that provides excellent corrosion resistance and long service life. With steel grades including SGCC and DX51D, and zinc coating weights ranging from Z60 to Z275, our coils are suitable for a wide range of building material applications.
