steel unequal angles

Unequal angle steel is widely used in various metal structures, bridge, machines, shipbuilding. The unequal angle steel which shall gain CCS, BV,ABS,NK,KR,RINA, LR, GL and DNV certification as well as related steel seal can used in shipbuilding. According to its surface quality regulations, layering, scab, crack and other defects are not permitted.
