How Much Does Corten Steel Cost Per Square Meter?
Corten steel pricing depends on thickness, finish, fabrication complexity and order quantity. Raw corten plate costs 20–40% more than equivalent mild steel, but the total project cost difference is smaller when you factor in zero painting and maintenance savings over the product lifetime.
Indicative pricing (2024–2025)
| Product Form | Price Range (USD/m²) | Notes |
|---|---|---|
| Raw corten plate (2mm) | $25–$40 | Ex-works, unprocessed |
| Raw corten plate (3mm) | $35–$55 | Ex-works, unprocessed |
| Raw corten plate (5mm) | $55–$80 | Ex-works, unprocessed |
| Laser-cut screen panel | $80–$200 | Depends on pattern complexity |
| Fabricated planter (per m² of steel used) | $100–$250 | Includes cutting, bending, welding |
| Pre-weathered finish (add-on) | +$15–$30/m² | Factory-applied stable patina |
What drives the price up or down
- Quantity: Orders above 5 tons typically get 10–15% better pricing due to mill-direct material sourcing.
- Thickness: Thicker plate costs more per m² but less per kg (material efficiency improves).
- Fabrication: Simple bends are cheap. Complex welded assemblies, curved forms and tight tolerances add significant cost.
- Finish: Raw (mill finish) is cheapest. Sandblasted, pre-weathered or sealed finishes add $15–50/m².
- Market conditions: Steel prices fluctuate with iron ore, energy costs and demand cycles. Prices above are indicative — request a current quote for accuracy.
Cost comparison: corten vs painted mild steel (10-year view)
A corten planter costs approximately 20–30% more upfront than an equivalent painted mild steel planter. However, the mild steel version needs repainting every 3–5 years at $30–60/m² per cycle. Over 10 years, the corten option is typically 30–40% cheaper in total cost of ownership.
