RMRS grade B ship building steel is certified by Russian classification society - Russian Maritime Register of Shipping, shorten as RMRS. RMRS grade B is equivalent to ABS grade B, BVB, CCSB, NV B, GL-B, KRB, LRB, KB, RINA-B. RMRS grade B ship building steel is usually in form of RMRS grade B steel plate, RMRS grade B angle steel and RMRS grade B bulb flat steel. And the RMRS grade B ship building steel is suitable for offshore platforms and hull fabrication.
