We supply Shipbuilding steel plate in two items, one is ordinary strength, grade A B D E and the others is higher strength, grade FH32/36/40, DHFH32/36/40, and FH32/36/40.

We hot rolled ship steel plates have through nine classification society DNV,ABS,LR,BV,GL,NK,RIAN,. Besides plates, our company also offer angle steel, bulb steel and flat steel profile for shipbuilding.

Our predominance is that we can offer super thick steel plate in Shipbuilding directly from our mill in competitive price and the fastest delivery time. For example,BV EH36 in thickness of 160mm,DNV FH32 in thickness of 110mm,and GL A in thickness of 170mm.All of them we could supply to our customers.

We have cooperated with Malaysia, Thailand, Korea, Singapore, Indonesia and Vietnam large shipyard and oil platform in steel plates and steel profiles. Just their large ship yard manager friends relation which has established our company sound reputation in oversea steel market.

If customers requirement, we also could supply the service of steel plates pretreatment, cutting in firmed drawing and bend pipe from steel plate.
