GB/T706-2008 Angle steel for shipbuilding

Shipbuilding Angle steel is one of the shipbuilding material which belongs to profiles. The shipbuilding steel angles required the certificate of ship classification of CCS, BV, LR, GL, DNV, ABS, NK, RS, KR, RINA etc.

GB/T706 Hot rolled section steels: it specifies the dimensions, shape, weight, tolerances, technical requirements, requirements for testing methods, inspection rules and so on.
