Panneaux d'écran en acier Corten
Corten steel screen panels are widely used as decorative products for gardens, bâtiments, and outdoor spaces. The raw material is usually corten steel sheet in thicknesses from 2 mm à 3 mm, which can be processed by laser cutting, flexion, soudage, and pre-rusting treatment. Because of its distinctive rusted surface and excellent weather resistance, corten steel has become a preferred material for screen panels, privacy partitions, and architectural decoration.
- Description
Corten steel screen panels are decorative metal products widely used in outdoor gardens, façades architecturales, privacy fences, and landscape partitions. The raw material for these panels is usually corten steel sheet, also called weathering steel sheet, which develops a natural rusted surface after exposure to the atmosphere. Because of its unique appearance and long outdoor durability, corten steel has become a common material for screen panels, wall art, and ornamental partitions.
Why Corten Steel Is Used for Screen Panels
Corten steel is especially suitable for decorative screens because it combines structural strength with a naturally aged appearance. The rust-colored surface creates an industrial and architectural style that is popular in modern landscaping and outdoor design.
Les applications courantes incluent:
- Brise-vue pour jardin
- Cloisons décoratives extérieures
- Balcony panels
- Fence inserts
- Building façade screens
- Laser-cut wall art
- Landscape feature panels
Comparé à l'acier au carbone ordinaire, corten steel forms a dense oxide layer that protects the interior metal, making it suitable for long-term outdoor exposure without additional paint.
Common Raw Material Thickness
Corten steel screen panels are generally made from thin to medium gauge weathering steel sheets.
| Épaisseur | Utilisation typique |
|---|---|
| 1.5 mm | Decorative indoor panels |
| 2.0 mm | Écrans de jardin |
| 3.0 mm | Panneaux d'intimité extérieurs |
| 4.0 mm | Fence and wall panels |
| 5.0 mm | Heavy-duty architectural screens |
The most common thickness for decorative corten screen panels is 2 mm à 3 mm, because this range offers a good balance between strength and precision cutting.
Processing Technology of Corten Steel Screen Panels
The manufacturing process of corten steel screen panels mainly includes several steps.
1. Material Cutting
The raw corten steel sheet is first cut into the required panel size. Les méthodes courantes incluent:
- CNC shearing
- Découpe plasma
- Découpe laser
For decorative products, fiber laser cutting is the most common process because it provides high precision for intricate patterns.
2. Pattern Engraving and Hollow Design
Most corten steel screen panels feature custom hollow patterns. These designs are created by laser cutting directly on the steel sheet.
Popular designs include:
- Motifs géométriques
- Motifs floraux
- Tree branch designs
- Abstract art
- Custom logos
- Architectural motifs
Laser cutting allows complex perforated shapes while keeping clean edge quality.
3. Bending and Frame Forming
Après avoir coupé, some panels require bending or edge folding to improve rigidity.
Méthodes de fabrication courantes:
- CNC press brake bending
- Profilage
- Welding frame support
Edge folding increases panel strength and reduces deformation during installation.
4. Soudage et assemblage
For larger decorative screen systems, additional supports may be welded.
This may include:
- Steel frames
- Mounting brackets
- Base plates
- Connection tabs
Corten steel can be welded using standard structural welding processes, although matching weathering steel welding wire is often used for consistent corrosion performance.
5. Surface Rusting Treatment
The final appearance of corten screen panels depends on surface oxidation.
Three common finishes are available:
| Surface Type | Description |
|---|---|
| Mill finish | Original dark steel surface |
| Natural rust | Weathered outdoors over time |
| Pré-rouillé | Artificial accelerated rust treatment |
Pre-rusted corten panels are often preferred for decorative projects because they achieve the finished appearance immediately after installation.
Advantages in Decorative Processing
Corten steel sheet is suitable for decorative screen manufacturing because it offers:
- Easy laser cutting
- Good bending performance
- Stable weldability
- Forte durabilité en extérieur
- Natural artistic rust finish
- À faible entretien
These properties make corten one of the most popular raw materials for custom metal landscape products.
