Crimped wire mesh is manufactured by pre-bending (crimping) both warp and weft wires before weaving, creating a rigid grid where wires are locked in position by the crimped interlocks. This construction prevents wire movement under high-tension loads, making it ideal for heavy-duty screening and filtration where precise mesh opening must be maintained under stress.
## Crimp Types
1. **Lock Crimp (Standard)**: Double-crimp pattern where both warp and weft wires are crimped at every intersection. Wires are positively locked — cannot shift under load. Most stable mesh configuration.
2. **Pre-Crimp (Intercrimp)**: Wires crimped at intervals (every 3rd or 5th intersection). More flexible than lock crimp. Used for lighter applications.
3. **Flat Top**: Crimps flattened on top surface for smooth finish. Used in architectural and decorative applications.
## Stainless Steel Advantages
- **SS304**: General-purpose stainless steel. Excellent corrosion resistance in atmospheric and freshwater environments. Food-grade compatible.
- **SS316**: Marine-grade stainless steel with molybdenum addition. Superior resistance to chloride corrosion (salt water, marine, chemical processing).
- **Temperature Resistance**: SS304 rated to 870C, SS316 to 800C continuous service.
- **Hygienic**: Non-porous surface, easy to clean, non-contaminating. FDA approved for food contact.
- **Aesthetic**: Bright, reflective surface maintains appearance without coating or painting.
## Key Advantages
- **Rigidity Under Load**: Lock-crimp construction maintains precise mesh opening under high-tension vibration and impact — critical for accurate screening.
- **High Temperature**: Stainless steel maintains strength at elevated temperatures — suitable for hot material screening.
- **Corrosion Proof**: SS316 option for salt water, acids, and chemicals. No coating to degrade.
- **Precise Open Area**: Consistent 10mm opening with 2.0mm wire = 69% open area. Optimized for flow rate and particle retention.
- **Long Service Life**: 20+ years in corrosive environments where carbon steel fails within months.
