From the heart of Hamilton’s industrial landscape, Latham Steel proudly supplies New Zealand’s key sectors with the exceptional BIRNAR 400 sheet and plate. As a trusted local manufacturer, we understand the demands placed on materials in our toughest industries, which is why we stand behind the proven resilience of BIRNAR 400. It is engineered to deliver unwavering strength and durability, providing a reliable foundation for projects where failure is not an option, ensuring structures and machinery are built to last.
BIRNAR 400 is a high-strength, low-alloy steel known for its excellent balance of toughness and formability. Its composition is carefully controlled to provide a minimum yield strength of 400 MPa, ensuring it can handle significant stress. This makes it significantly stronger than standard mild steel, yet it remains workable for fabrication. The material offers good weldability and maintains its structural integrity, making it a dependable choice for engineers and fabricators who need a material that performs consistently under pressure.
