Product Description

Marine steel plates refer to hot-rolled steel plates used to manufacture ship hull structures produced in accordance with the requirements of classification society construction specifications.
Shipbuilding structural steel plates are divided into strength grades according to their minimum yield points: ordinary strength structural steel plates and high-strength alloy structural steel plates. Marine structural steel plates are divided into two types: ordinary strength ship plates and high strength ship plates. Ordinary strength steel is divided into four grades: A, B, D, and E according to quality; high-strength steel is divided into two strength grades and three quality grades; AH32, DH32, EH32, AH36, DH36, and EH36.
The ordinary strength structural steel in the China Classification Society standards is divided into four quality grades A, B, C, and D (i.e., CCSA, CCSB, CCSC, CCSD); the high-strength structural steel standards of the China Classification Society are three strength grades. , four quality levels.
Classification Society Rules
CCS (China), ABS (USA), GL (Germany), BV (France), DNV (Norway), KDK (Japan), LR (UK).
