From the industrial heart of Hamilton, New Zealand, Latham Steel proudly stands as a trusted source for Corten steel sheet and plate. We understand that this unique material is more than just a product; it’s the foundation for creations that blend strength with a distinct, weathered character. We are committed to supplying high-quality Corten directly to fabricators, artists, and builders across the country, providing the essential building blocks for projects that are designed to endure and evolve beautifully over time.
What makes Corten steel so special is its distinctive chemical composition. It forms a stable, self-healing rust-like patina when exposed to the elements, which actually protects the inner layers from further corrosion. This unique characteristic means it requires no painting, creating a very practical, low-maintenance solution. Beneath that protective skin, the material retains excellent mechanical strength and toughness, allowing it to withstand significant structural loads and harsh weather conditions for decades without compromising its integrity.
