ABS AH36 DH36 EH36 FH36 shipbuilding plate
Marine structures – such as offshore cranes – and cargo ships must be able to endure extreme conditions without fracturing or corroding. Materials used to build these structures – including steel plate – are highly regulated and standardized to ensure the structures can withstand maritime conditions. Steel plate materials used in these capacities are known as marine and offshore steel plate.
While shipbuilding applications primarily use ABS steel plate, other grades – such as ASTM A131 – may also meet the regulatory standards required for shipbuilding use. These grades are typically ordered with ASTM specifications that are certified by ABS, meaning the plate is produced by an ABS approved mill and has mill test reports stamped by ABS. This process ensures that non-ABS grades meet all the necessary regulatory standards for use in constructing marine vessels.
