Corten Steel Flat Bar

Corten Steel Flat Bar is a flat-profiled structural steel product made from weathering steel, designed to resist atmospheric corrosion through the formation of a stable, self-protecting rust-like patina. These flat bars offer the ideal combination of strength, durability, and aesthetic appeal, making them highly suitable for architectural, structural, and outdoor design applications.

Available in a variety of widths and thicknesses, Corten flat bars are an excellent choice for frameworks, edge trims, cladding, fencing, and other exposed steel elements that require minimal maintenance and a rustic appearance.
