Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications.
The main characteristics of galvanized steel coil have strong corrosion resistance, good surface quality, which are beneficial to further processing, economical and practical. Prime hot dipped galvanized steel coil covers Southeast Asia, Middle East, Africa and South America market.
