S355g7+M and S355g7+N plates both are structural steel plate grades and mainly used in offshore industry. S355g7+M means thermo-mechanically rolled and S355g7+N means normalised steel plate. These both S355g7+M / N structural steel plate offers good tensile and yield strength and supplied as per EN10225:2001 standard. These S355g7+M and S355g7+N Plate are used to build offshore platforms in offshore industries. BBN steel would completely manufacture S355g7+N steel plates according to steel standard EN 10225 and mill test certificate would be issued under format EN 10204 TYPE 3.1.
