From the heart of Hamilton’s industrial landscape, Latham Steel stands as a trusted local source for high-grade materials, proudly supplying New Zealand’s builders and fabricators with ARCELOR 400 sheet and plate. We understand that robust projects demand reliable foundations, which is why we ensure consistent access to this exceptionally strong steel. Our team is dedicated to providing not just the product, but the expert support needed to bring ambitious designs to life, right here in our own community.
ARCELOR 400 is a high-strength, low-alloy steel that strikes an impressive balance between durability and workability. Its carefully controlled composition results in a minimum yield strength of 400 MPa, offering remarkable resistance to wear and impact. This strength means you can often use thinner, lighter sections without compromising the integrity of your structure, leading to more efficient and often more economical designs. It also possesses good weldability and machinability for a steel of its strength.
