For over forty years, Latham Steel in Hamilton has been the trusted local source for industrial and architectural materials, forging a reputation built on reliability and expert knowledge. We are particularly proud to supply Corten Steel S355J2W, a material that perfectly embodies New Zealand’s rugged character. This exceptional steel is designed to develop a stable, self-protecting rust layer when exposed to the elements, making it an ideal choice for projects that demand both enduring strength and a distinctive, weathered aesthetic right from the start.
The strength of S355J2W lies in its specific composition and performance. The steel is alloyed with elements like copper, chromium, and nickel, which work in concert to form a dense, adherent patina that halts further corrosion. This protective barrier allows it to withstand harsh weather far better than standard steel. Mechanically, it offers a minimum yield strength of 355 MPa, ensuring exceptional structural integrity and load-bearing capacity for demanding applications where longevity is non-negotiable.
