From the industrial heart of Hamilton, Latham Steel has built a strong reputation as a trusted local source for high-strength steel. We are proud to supply the durable and versatile ASTM A572 Gr 50 sheet and plate, a product chosen by New Zealand’s leading fabricators and engineers for its exceptional performance. Our team understands the demands of local projects, ensuring you receive material that consistently meets the toughest specifications, backed by reliable service and expert support right here in our community.
The composition of A572 Gr 50 is a careful balance, primarily of carbon, manganese, and phosphorus, with small but vital additions like columbium-vanadium that significantly boost its strength. This recipe gives the steel its notable mechanical properties, including a minimum yield strength of 50,000 psi and excellent weldability. It’s this high strength-to-weight ratio that makes it such a practical choice, offering the robustness needed for major projects without adding unnecessary bulk or complication to the fabrication process.
