Pageviews:

CCS marine grade steel plates refer to the hot rolled steel plates produced according to the requirements of China Classification Society's construction specifications for the manufacture of hull structure. According to the minimum yield point, CCS marine grade steel plates are classified into three strength grades and four quality grades:

General strength CCS marine grade steel plates: CCS grade A, CCS grade B, CCS grade D, CCS grade E.

High strength CCS marine grade steel plates: CCS grade AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, FH36, FH40.

Ultra high strength CCS marine grade steel plates: CCS grade AH420, DH420, EH420, FH420; AH460, DH460, EH460, FH460; AH500, DH500, EH500, FH500; AH550, DH550, EH550, FH550; AH620, DH620, EH620, FH620; AH690, DH690, EH690, FH690.

The thickness of CCS marine grade steel plates is usually within 150mm. The lower marine grade steel plates thickness limit we have is 3mm. CCS marine grade steel plates are mainly used to build the hull structure of ocean going, coastal and inland navigation ships. Other than CCS, we also cooperated with ABS, BV, LR, DNV GL, RINA, NK, KR, RMRS, etc. classification societies.
