Product Description
DC51D+ZM DC52D+ZM Zn-Al-Mg Zinc Aluminum Magnesium Coated Steel Sheet
ZM Steel Coils are specially designed steel sheets employed in various building construction and decoration applications. These steel coils consist of thin sheets that can be rolled into continuous coils. ZM coil is particularly suitable for outdoor use due to its excellent anti-rust properties.
Zinc-aluminum-magnesium ternary alloy coated steel strip offers superior corrosion resistance, with performance more than 5 times greater than pure zinc-coated products (GI) of the same coating weight. The corrosion resistance at cut edges is especially notable, making it suitable for replacing hot-dip galvanized steel strip in many applications.
