Shipbuilding Steel

We focus on series of shipbuilding steel products which including steel plates and sections (Bulb flat, equilateral angle, unequal angle, inequilateral and unequal-thickness L-shaped steel). Those products have strict control on chemical composition of steel as per requirements of domestic and international classification societies, e.g. CCS, ABS, GL, BV, DNV, LR, NK, KR, RINA and GB712. By the rolling processes such as AR, CR, TMCP, QT, the excellent mechanical properties can be obtained.
