DX51D+Z Hot-Dip Galvanized Steel Coil
Continuous hot-dip zinc coated coil to EN 10346
DX51D+Z is the commercial-quality galvanized coil grade: a low-carbon substrate with a continuous hot-dip zinc coating from Z100 to Z350. It is not intended for structural use, which is exactly why it forms and bends so well. For roofing, ducting, appliance bodies and general panel work, this is the grade your fabricator will ask for by name, and it is quoted against SGCC and ASTM A653 CS.
