Continuous hot-dip galvanized coil in DX51D+Z for roll-forming, stamping, painting and structural components.
DX51D+Z galvanized steel coil is produced by continuous hot-dip galvanizing of low-carbon strip. The uniform zinc coating provides edge-to-edge corrosion protection, while the soft substrate is ideal for roll forming, deep drawing and profiling. It is the standard feedstock for building profiles, appliance parts and downstream coated products.

Applications
DX51D+Z galvanized coil is used for roll-formed roofing and purlins, cable trays and raceways, lighting fixtures, appliance cabinets, car body repair panels, storage rack components, and as substrate for color-coated (PPGI) production. For cut sheets see our DX51D+Z galvanized sheet, and for structural sections galvanized angle, channel and strip.
