ASTM A653M

What is ASTM A653M?

This Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron Alloy-Coated (Galvannealed) by the Hot-Dip Process

ASTM A653M specification covers steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process in coils and cut lengths.

Chinese standard: GBT 2518-2008

European standard: EN10147

Japanese standard: JIS G3302

 

What is G30 VS G90?

 G90 refers to the average minimum weight of the galvanized sheet measured at three points on both sides of 0.9oz/ft2, which is the SI unit of 275g/m2. The conversion relation between them is 1oz=0.0284kg, so 0.9oz=0. 02556kg=25.56g 1ft2=0.093m2 25.56g/0.093m2=275g/m2.

 

The correspondence between the G and Z labels is as follows:

G90——Z275

G75——Z230

G70——Z215

G65——Z200

G60——Z180

G50——Z150

G40——Z120

G30——Z90
