The material for this Laser Cut Screen is Corten steel (COR-TEN A or B), a high-strength, weathering steel widely used in architectural and landscape design.
Corten steel has a tensile strength of 480–620 MPa and a yield strength of 355 MPa, making it highly durable and able to withstand harsh weather conditions without the need for painting or coating.
Over time, Corten forms a stable rust layer that protects the steel from further corrosion, providing long-lasting, maintenance-free performance.
This laser-cut metal Screen is custom-designed and installed for a riverfront mid-century modern home, acting as a stylish room divider between two adjacent patios.
The design incorporates circular motifs inspired by the interior fabrics and fixtures, combined with contemporary geometric shapes that reinterpret mid-century modern standards.
Chemical Composition
| Element | COR-TEN A (%) | COR-TEN B (%) | Notes |
|---|---|---|---|
| Carbon (C) | 0.12 - 0.20 | 0.12 - 0.21 | Low carbon content for weldability |
| Manganese (Mn) | 0.25 - 1.35 | 0.25 - 1.35 | Improves strength and hardness |
| Phosphorus (P) | ≤ 0.07 | ≤ 0.07 | Controlled to reduce brittleness |
| Sulfur (S) | ≤ 0.03 | ≤ 0.03 | Low sulfur ensures toughness |
| Silicon (Si) | 0.20 - 0.50 | 0.20 - 0.50 | Enhances oxidation resistance |
| Copper (Cu) | 0.25 - 0.55 | 0.25 - 0.55 | Improves atmospheric corrosion resistance |
| Chromium (Cr) | 0.50 | 0.50 | Added to improve corrosion resistance |
| Nickel (Ni) | - | 0.65 | Only in COR-TEN B, enhances toughness |

The screen thickness ranges from 1.5 mm to 6 mm, suitable for both structural stability and fine laser-cut detail. Using advanced laser cutting technology, each panel achieves precise perforation with tolerances as low as ±0.1 mm, enabling intricate designs while maintaining structural integrity.
Whether placed in a garden, on a city square, or in a residential project, this Laser Cut Corten Steel Screen enhances the landscape with both aesthetic appeal and durability.
Its low-maintenance, weather-resistant properties, combined with customizable size (typically 2–3 m high and 1–3 m wide), make it ideal for both functional and decorative applications.
