Ship Hull Structural Steel Suppliers & Manufacturers
Hull structural steel is a steel specially designed for ships and marine structures. It has high strength, corrosion resistance, and fatigue resistance, and can withstand harsh marine environments and high pressure loads. These steels usually meet the quality standards of international classification society certification (such as ABS, DNV, LR, etc.) and are widely used in hull manufacturing, deck construction, ship cabins, and other marine engineering structures.
At Huaxiao Metal, we provide high-quality hull structural steel that meets various standards and specifications to meet the different needs of shipbuilding and marine engineering.

Frequently Asked Questions (FAQ): Ship Hull Steel
What are the standards for hull structural steel?
Ship hull structural steel must comply with the standards of international classification societies such as ABS, DNV GL, LR, and BV. These standards ensure that the quality of steel can meet the requirements of shipbuilding and marine engineering.
Does hull structural steel have corrosion resistance?
Yes, hull structural steel is generally corrosion-resistant, especially those specially treated weathering steels, which are suitable for long-term use in marine environments.
What is the difference between ordinary strength hull steel and high strength hull steel?
Ordinary strength hull steel is used for conventional hull structures, while high strength hull steel is suitable for ships and deep-sea engineering with higher load requirements, providing better strength and fatigue resistance.
