Shipbuilding plate A131 grade A steel plates

Shipbuilding plate A131 grade A is defined as ordinary strength steel with specified minimum yield of 34KSI (235Mpa). Applications of A131 grade A steel plates include barges, marine equipment and ship construction.

Our A131 grade A steel plates are supplied with certificates approved from nine international classification societies, such as ABS, LR, DNV GL, CCS, NK, BV, RINA, KR.

Shipbuilding plate A131 grade A with large width and heavy thickness is recommended to do Z-test when rolling, which can improved the steel properity in thickness direction. There are three class Z-test for choosing, such as Z15, Z25 and Z35.
