ASK:
ANSWER:S350GD is a steel grade in European standard EN10346, S350GD is construction quality steel material, The material No. of S350GD is 1.0529.
+ZM means Hot-dip Zinc-magnesium alloy coated, application of a Zinc-magnesium coating by immersing the prepared strip in a molten bath of zinc-aluminum-magnesium. The composition of the bath is sum of aluminium and magnesium from 1.5%-8%, containing minimum of 0.2% magnesium and the balance zinc. So S350GD+ZM means hot dip Zinc-magnesium coated, structural material steel.
S350GD+ZM material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
S350GD+ZM steel coating finish is N(Normal spangle) or M(Minimized spangle)
S350GD+ZM steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
S350GD+ZM steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
S350GD+ZM steel Coating mass are: ZM060, ZM070, ZM080,ZM090,ZM100,ZM120, ZM130, ZM140, ZM150, ZM160, ZM175, ZM190, ZM200, ZM250, ZM300, ZM310, ZM350, ZM430
S350GD+ZM steel mechanical property:
Proof strength should be not less than 350MPa
Tensile strength should be not less than 420MPa
Elongation A80 should be not less than 16%
