Galvanized steel plate S350GD+Z,S350GD,S350GD+ZF steel coil
Source:Xin Steel Industry Date:2012/08/16
S350GD+Z,S350GD,S350GD+ZF hot-dip galvanized steel plate are used for structural steel.After rolling galvanized steel sheet S350GD,S350GD+Z,S350GD+ZF,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 S350GD+Z,S350GD+ZF,S350GD.However,the following precautionary measures should be taken:secure packing,laid flat,no local pressure spots.
Sealed treatment for galvanized steel plate and coil S350GD+Z,S350GD,S350GD+ZF shall be chosed after rolled finished,application of a transparent organic film coating of mass about 1g/m2.
