What is crimped wire mesh?
In crimped mesh the wires are corrugated (crimped) at the crossing points before or during weaving, so the wires lock together and resist shifting under heavy vibration and abrasion. It uses thicker wire than fine woven mesh and is built for screening hard, abrasive bulk materials. It is supplied as flat panels, hooked screen sections or rolls.
Crimp patterns
| Pattern | How it is formed | Best for |
|---|---|---|
| Double crimp (intercrimp) | Both wires crimped and interlocked at every intersection | General screening, medium apertures |
| Lock crimp | Deep crimp locks wires firmly at each cross point | Heavy vibration, secure apertures |
| Pre-crimp (single) | Wires crimped before weaving, often one direction | Larger apertures, heavy wire |
| Flat top / ton cap | Smooth wear surface on one side | Reduced wear, smoother material flow |
Aperture range and wire diameter
Crimped screens cover a wide aperture range with correspondingly heavy wire. Larger openings need thicker wire to carry the load and resist abrasion. The table gives representative pairings; confirm exact wire diameter against the duty and material being screened.
| Aperture (mm) | Typical wire dia. (mm) | Typical duty |
|---|---|---|
| 2 - 5 | 1.6 - 3.0 | Fine aggregate, sand grading |
| 6 - 12 | 3.0 - 5.0 | General quarry screening |
| 13 - 25 | 4.0 - 8.0 | Coarse aggregate |
| 30 - 50 | 6.0 - 12.0 | Heavy coarse material |
| 60 - 100 | 8.0 - 16.0 | Primary scalping screens |
Materials
- High-carbon / spring steel: high tensile strength and wear resistance for abrasive screening.
- Manganese steel: work-hardens under impact for the longest life on harsh primary screens.
- Galvanised mild steel: economical for less abrasive or indoor screening.
- Stainless steel: for food, chemical or corrosive screening duties.
Where crimped mesh is used
- Vibrating screens for screening and sieving aggregate, sand and gravel.
- Mining and quarrying - scalping, sizing and dewatering screens.
- Recycling and material handling - separating crushed material by size.
- Architecture and infill - decorative heavy-grid panels and barriers.
How to choose and buy crimped mesh
Start with the cut point (aperture) you need, then select a wire diameter heavy enough for the material's abrasiveness and the screen's vibration. Specify the crimp pattern, panel size and any hooked edges to fit the screen deck. Estimate panel weight with the weight calculator and confirm the alloy for wear life.
For highly abrasive material, a heavier wire or manganese steel costs more upfront but reduces screen downtime and replacement frequency.
