APPLICATIONS OF STRUCTURAL CORTEN STEEL
Weathering steel is selected for its high strength, reduced long-term maintenance, and distinctive rust-like patina. Common applications include:
Building structures and exposed steel components
Architectural cladding, screens, and accents
Bridges, guardrails, and transportation infrastructure
Landscape features, retaining walls, public art
Industrial and marine-adjacent structures
The natural oxidation process forms a stable, protective layer, dramatically reducing the need for long-term coating or maintenance in suitable environments.
LEAD TIMES
Lead times vary based on grade, volume, and size range:
Stock items: Typically ship within a few days
Mill-order plate and structural sections: 3-4 weeks
Large structural: 4–6 weeks depending on mill schedules
