Gnee CCS shipbuilding steel is certified and offers exceptional strength and durability. Competitive prices, customized cutting, rigorous testing, comprehensive sizes and grades, single pieces or large-scale project bulk purchases are available, 24/7 after-sales service.

CCS shipbuilding steels are steels specially designed and approved by China Classification Society (CCS) for shipbuilding.

CCS shipbuilding steels typically include various grades of structural steel with specific mechanical properties, such as high strength and excellent weldability, to meet the demanding requirements of ship construction. These steels are used in the construction of various ship components including hulls, decks and superstructures.

Specific grades of CCS shipbuilding steels may vary depending on the requirements of the ship being built. Some commonly used CCS grades include CCSA, CCSB, CCSD, CCSE, and others. These grades are usually followed by a numerical value indicating the yield strength of the steel, such as CCSA550 or CCSB620.

It is worth noting that CCS shipbuilding steels are specific to the standards and regulations set by Chinese classification societies. Other classification societies, such as American Bureau of Shipping (ABS) or Lloyd’s Register (LR), may have their own approved grades for shipbuilding steel.
