Is exterior corten steel cladding panels expensive - Gnee Garden
Mar 31, 2026
Leave a message
Exterior corten steel cladding is considered a premium material with a high initial cost, typically 1.5 to 2.5 times more expensive than standard steel due to its alloying elements and specialized production.
Corten steel cladding has become one of the most popular architectural materials in modern construction. It is widely used in building facades, landscape design, and outdoor structures.

The Price of corten steel cladding panels
Prices can range from $600 to $1,200 per tonne, depending on material thickness, finishes, and supplier.
Unlike ordinary metal cladding, which requires ongoing painting or protective coatings, exterior corten steel cladding develops a self-protecting rust-like layer called a patina. This unique surface not only enhances its aesthetic appeal but also shields the steel underneath from further corrosion.
Because of its high-strength, low-alloy composition and added durability, Corten Steel Cladding typically costs more upfront than mild steel or standard cladding materials.

Key Factors for Extending Cladding Lifespan
Prevent prolonged water accumulation on cladding: Ensure adequate drainage space is provided during installation to prevent moisture retention and material corrosion.
Avoid burying weathering steel cladding in soil: Soil disrupts the stability of the rust layer, triggering severe corrosion.
Addressing uneven rust patina: Variations in rust appearance due to differences in sunlight exposure and rainfall can be mitigated through gentle cleaning. Over time, the colours will naturally harmonise and unify.
