ABS steel plates

ABS steel plates are types of structural steel that are standardized by the American Bureau of Shipping for use in shipbuilding.

ABS steel plates are types of structural steel that are standardized by the American Bureau of Shipping for use in shipbuilding.

Main grades of ABS steel plates

ABS steels come in many grades in ordinary-strength and two levels of higher-strength specifications.

Ship Structural Steel Plate, Ship Steel Plate, Marine Steel Plate manufacturer/supplier in China, offering ABS Grade a Ship Structural Marine Steel Plate, Dx51d Dx52D PPGI Color Coated Steel Coil, SGCC Z100 Color Coated Pre-Painted Galvanized Steel Coil and so on.

All of these steels have been engineered to be optimal long-lived shipbuilding steels. ABS does permit the use of other steels in shipbuilding, but discourages it, and requires more detailed engineering analysis.
