Latham Steel, based in the industrious heart of Hamilton, New Zealand, is a trusted local source for robust and enduring steel solutions. We take pride in supplying high-performance ASTM A242 Type 2 Corten steel in both sheet and plate forms. Known for its distinctive, rustic appearance and exceptional durability, this material is a prime choice for projects where both structural integrity and aesthetic character are key considerations, offering a unique blend of strength and long-lasting performance directly from our New Zealand facility to your site.
The specific composition of ASTM A242 Type 2 Corten includes added elements like copper, chromium, and nickel, which work together to create its remarkable quality. When exposed to the weather, it forms a tight, protective patina that resists further corrosion, essentially healing itself. This results in impressive mechanical properties, including a high yield strength that provides excellent load-bearing capacity, making it significantly stronger and more resilient than many standard carbon steels, especially in challenging outdoor environments.

The uses for this versatile steel are as practical as they are visually striking. It is famously employed in architectural facades, bridges, and sculptural installations, where its evolving, warm-toned patina becomes a living part of the design. Beyond aesthetics, its strength and corrosion resistance make it ideal for heavy-duty applications like shipping containers, industrial structures, and outdoor utility buildings. Essentially, it’s the perfect material for creating lasting structures that are designed to age gracefully and withstand the elements with minimal maintenance.
