EN 10147 S320GD+Z,S320GD+ZF,S320GD hot dipped galvanized steel plate,after trolled and transport,dark spots may appear on the zinc coated surfaces as a result of friction.Generally,these spots only impair the appearance.Friction is reduced by oiling the galvanized steel plates and coils of S320GD+Z,S320GD+ZF,S320GD.However,the following precautionary measures should be taken:secure packing,laid flat,no local pressure spots.
In the old version steel standard EN 10147:1991,the name of galvanized steel plate S320GD+Z as Fe E320 G Z,and galvanized steel plate S320GD+ZF named as Fe E320 G ZF.Now xinsteel give the mechanical properties for galvanized steel S320GD+Z,S320GD+ZF as belows:
