Crimped Wire Screen with Selvedge Edge: Technical Overview
Crimped wire screens with selvedge edges are specialized woven wire meshes designed for durability, stability, and easy installation in industrial and architectural applications. The crimping process (pre-weaving wire bending) enhances load-bearing capacity, while the selvedge edge (a reinforced border) prevents fraying and simplifies mounting.
1. Key Features & Benefits
✔ Enhanced Strength – Crimped wires interlock to resist deformation under pressure.
✔ Selvedge Edge – Reinforced with thicker wire or folded weft wires for clean, safe edges.
✔ Stable Openings – Uniform apertures even under vibration or impact.
✔ Easy Installation – Selvedge allows direct bolting, clamping, or welding.
2. Common Materials & Specifications
| Parameter | Options | Typical Use Cases |
|---|---|---|
| Material | Stainless steel (304/316), carbon steel, galvanized steel, brass | Filters, sieves, machine guards |
| Wire Diameter | 0.5mm–8mm | Fine screens: 0.5–2mm; heavy-duty: 3–8mm |
| Mesh Size | 1mm–100mm (aperture) | Small: particle filtering; large: safety barriers |
| Crimp Type | Lock crimp, intermediate crimp, flat top | Lock crimp for high vibration resistance |
| Selvedge Edge | Double wire, folded weft, or welded border | Secures mesh to frames or structures |
3. Crimp Types (Illustrated)
- Lock Crimp: Wires “lock” at intersections for maximum stability.
- Intermediate Crimp: Balanced flexibility and strength.
- Flat Top Crimp: Smooth surface for material flow (e.g., conveyor screens).
4. Selvedge Edge Styles
| Type | Description | Advantages |
|---|---|---|
| Double Wire | Two parallel edge wires for reinforcement | Prevents unravelling, handles tension |
| Folded Weft | Weft wires bent back into the mesh | Clean finish, no sharp edges |
| Welded Border | Edge welded to a frame or strip | Rigid mounting, no fraying |
5. Applications
- Mining & Quarrying: Trommel screens, vibrating sieves.
- Agriculture: Grain sorting, animal fencing.
- Architecture: Decorative facades, balcony screens.
- Industrial: Safety guards, heat-resistant barriers.
6. Ordering Specifications
