ASK:
ANSWER:S280GD is a steel grade in European standard,S280GD is construction quality steel material, The material No. of S280GD is 1.025.
+Z means hot dip Zinc coating. The zinc content is at least 99% . So S280GD+Z means hot dip zinc coated, structural material steel.
S280GD+Z material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
S280GD+Z steel coating finish is N(Normal spangle) or M(Minimized spangle)
S280GD+Z steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
S280GD+Z steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate), PO (phosphate and oiled), S (sealed)
S280GD+Z steel Coating mass are: Z60/Z80/Z100/Z410/Z200/Z225/Z275/Z350/Z450/Z600
S280GD+Z steel mechanical property:
Yield strength should be not less than 280MPa
Tensile strength should be not less than 360MPa
Elongation A80 should be not less than 18%
