Corten steel siding panels, also called Corten Steel Claddings, are widely used for exterior walls due to their natural rust appearance, high durability, and low maintenance requirements.
How Corten Steel Siding Panels Are Made
- Corten steel panels are produced from weathering steel plates. The manufacturing process includes:
- Cutting steel plates by laser or plasma
- Bending or roll forming into flat or profiled panels
- Optional pre-weathering to achieve a uniform rusted surface
- Quality inspection and protective packaging

How to Install Corten Steel Siding Panels
Corten steel siding is usually installed as a ventilated façade system:
- Prepare the wall with a waterproof layer
- Install a galvanized steel or aluminum sub-frame
- Fix panels using visible fasteners or hidden clip systems
- Leave expansion gaps to allow thermal movement
Important Tips
- Rust Management: During the first few months, rain will cause rust runoff that can stain surrounding materials. Use protective covering on the ground initially.
- Accelerating Patina: To speed up the rustic, orange-brown finish (which usually takes 6 months), spray with a mixture of water, hydrogen peroxide, and salt/vinegar.
- Dissimilar Metals: Avoid direct contact with copper, lead, or other dissimilar metals to prevent galvanic corrosion.
