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 HX420LAD,HX420LAD+Z,HX420LAD+ZF,H420LAD,
H420LAD+ZF,H420LAD+Z.However,the following precautionary measures should be taken:secure packing,laid flat,no local pressure spots.
