Steel Plate for Marine and Offshore Applications
At BMG, we provide marine- and offshore-grade steel plates that meet ABS (American Bureau of Shipping) certification requirements.
ABS STEEL PLATE
ABS steel (American Bureau of Shipping) is a high-strength steel used primarily in the construction of ships and marine platforms. Different ABS steel grades, such as Grade A, B, AH36, DH36, and EH36, provide a range of mechanical properties to meet diverse needs in the fabrication of maritime structures and drilling platforms. These steels are specifically designed to withstand harsh sea conditions and the marine environment.
ABS steel is produced in accordance with American Bureau of Shipping standards to ensure its suitability for the manufacture of vessels and other marine structures. Grades such as A and B are intended for more general applications, while grades AH36, DH36, and EH36 are suitable for structures requiring higher strength and toughness, especially under extreme temperature and mechanical stress conditions.
Grade A: Suitable for general use in structures that will not be exposed to extreme conditions.
Grade B: Similar to Grade A, but with slightly improved characteristics.
Grades AH36, DH36, EH36: Higher tensile strength steels used in structures operating under high loads, low temperatures, and demanding marine environments.
- High tensile strength and low-temperature toughness.
- Excellent resistance to marine corrosion.
- Good weldability and formability.
- Versatility in marine applications, from vessels to platforms.
- Compliance with American Bureau of Shipping (ABS) standards.
- Specific mechanical properties to withstand high mechanical stresses and extreme conditions.
- Shipbuilding Industry: Construction of ship hulls, commercial and military vessels, and drilling platforms.
- Maritime Industry: Manufacture of marine structures such as offshore platforms and vessels for oil and gas transportation.
- Offshore Industry: Structural components for drilling platforms and other offshore infrastructure.
- Infrastructure Construction: Use in bridges, floating platforms, and other structures exposed to saltwater.
