Steel is the backbone of Hamilton’s industrial landscape, and for decades, Latham Steel has been a cornerstone of this community. We are proud to supply local fabricators and major national projects with materials built to endure, including the exceptional BIRNAR 500 Sheet and Plates. This high-strength, low-alloy steel is engineered for demanding applications, offering a superior combination of durability and weldability that our customers can rely on to build stronger, safer, and more resilient structures right here in New Zealand and beyond.
BIRNAR 500 is a high-strength, low-alloy steel engineered for resilience. Its precise composition results in impressive mechanical properties, including a minimum yield strength of 500 MPa, which provides exceptional resistance to heavy loads and impacts. This strength is complemented by good elongation, allowing it to be formed and shaped without compromising its integrity. The material also offers excellent weldability, ensuring it can be easily incorporated into complex fabrications while maintaining its robust performance characteristics for the long term.
