From the industrious heart of Hamilton, New Zealand, Latham Steel proudly supplies the backbone of modern maritime engineering: ABS AH36 shipbuilding steel sheet and plates. We understand that the integrity of a vessel begins with the quality of its materials, which is why we provide this high-strength steel to shipyards and fabricators who cannot compromise on safety or performance. Trust in Latham Steel for a reliable supply of the robust foundations needed to build structures that confidently face the relentless forces of the ocean.
This specific grade is a low-carbon alloy steel, carefully formulated with elements like manganese and phosphorus to achieve its notable strength. The “AH36” designation confirms its high yield strength of 36 ksi (or 355 MPa), ensuring exceptional toughness and resistance to impact, even in colder environments. Its excellent weldability is a key feature, allowing for efficient and secure construction of complex hull sections without compromising the material’s inherent durability under heavy loads and dynamic stresses.

The primary use for ABS AH36 steel is, as the name implies, in the construction of ship hulls, decks, and other critical structural components for commercial vessels, naval ships, and offshore platforms. Its high strength-to-weight ratio is crucial for building larger, more fuel-efficient ships that can withstand the immense pressures of heavy cargo and punishing sea conditions. Beyond shipbuilding, this steel is also trusted for heavy-duty applications in bridge building, mining equipment, and any project demanding superior load-bearing capacity and resilience.
Latham Steel is a leading manufacturer, supplier and exporter of high-quality Carbon Steel, Alloy Steel, Mild Steel and Galvanized Steel products.
