Cold-rolled weathering steel is a high-performance, corrosion-resistant steel specifically engineered for outdoor applications where durability and minimal maintenance are critical. Through an advanced cold-rolling process, this steel achieves superior surface smoothness, precise dimensional tolerances, and enhanced mechanical properties compared to traditional hot-rolled weathering steel.
The unique alloy composition forms a stable, self-protecting rust-like patina when exposed to weather, eliminating the need for painting while maintaining structural integrity for decades. This makes it ideal for architectural facades, bridges, shipping containers, and outdoor sculptures.
Our cold-rolled weathering steel offers:
1.Excellent atmospheric corrosion resistance (2-8x better than carbon steel)
2.Superior strength-to-weight ratio for lightweight designs
3.Consistent material properties with tight thickness control (±0.03mm)
4.Aesthetic, even patina development over time
5.Full recyclability and environmental sustainability
Available in standard grades like ASTM A606-4 and custom compositions, it meets international standards for weathering steel applications. The cold-rolled version provides enhanced formability for complex architectural shapes while maintaining all the weathering advantages of conventional COR-TEN steel.
