Galvanized Steel Coil is a metal material that uses cold-rolled steel sheets as the base material and forms a uniform zinc layer through a hot-dip galvanizing process. Its surface zinc layer provides excellent corrosion resistance, is suitable for humid environments, and has a long service life. It has both good formability and strength adjustability (covering 220-550MPa levels), and is widely used in construction, home appliances, automobiles, and industrial equipment manufacturing.
