Shipyards use shipbuilding steel plate NV F420 to construct tanks and vessels in ships cause DNV F420 ship plate owned the higher yield strength and tensile strength. Xinsteel group owned tens of stock warehouses in port cities in China,there are thousands tons of shipbuilding steel plate and sheet and angles and buld flats in stock which are ready to ship on board.Different thicknesses,width mainly in 2000-2500mm,length mainly in 6000-12000mm for steel plate DNV Grade F420.

Our normal rolling period for ship plate DNV F420 shall be about 25 days with quenching and tempering for hundreds tons,and then DNV agency would come to our mill for sample inspection before shipment,and finally our mill issue the mill test certificates for each plate and DNV agency stamped and endorsed on our Mill test certificates.So this systerm can gurantee all our plates are properity and quality.Else,our mill had cooperated with other eight classification societies,such as LR,GL,BV,ABS,NK,CCS,RINA,KR.
