Our Product
Corten steel, also known as weathering steel, is a low-alloy high-strength material with excellent resistance to atmospheric corrosion.
Its surface naturally forms a stable rust-like protective layer in outdoor environments, which enhances durability while presenting a distinctive industrial aesthetic.
We offer a full range of Corten steel products, covering both raw materials and fabricated components, widely used in architecture, landscaping, gardening, and industrial applications.
Our offerings include Corten steel plates, welded and seamless pipes, angle steel, channel steel, H-beams, and more. We also provide custom-fabricated products such as Corten planters, raised beds, facade panels, sculptures, water features, privacy screens, fences, and laser-cut signage.
These products are extensively used in building facades, urban landscapes, garden design, public art installations, and infrastructure projects, offering both structural strength and visual appeal - highly favored by designers and engineers worldwide.
