Crimped Wire Mesh: Patterns, Specs & Uses
Quick answer
Crimped wire mesh is a heavy-duty woven screen in which the wires are pre-bent (crimped) before interlocking, giving robust, stable apertures that make it the standard medium for vibrating screens in mining, quarrying and aggregate screening.

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.
Figure summary: Crimped wire mesh uses wires that are pre-crimped (waved) before weaving, so they lock together at the crimps. This gives a stable, heavy-duty screen that resists distortion, widely used on vibrating screens, in mining, quarrying and architectural screening.

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.

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.
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.
Tip
For highly abrasive material, a heavier wire or manganese steel costs more upfront but reduces screen downtime and replacement frequency.
Frequently asked questions
What is crimped wire mesh used for?
Crimped wire mesh is mainly used as screening media on vibrating screens in mining, quarrying, aggregate and recycling plants. The crimped, interlocked wires hold heavy apertures stable under vibration and abrasion, making it ideal for sizing, scalping and dewatering crushed stone, sand and gravel.
What is the difference between lock crimp and intercrimp mesh?
Intercrimp (double crimp) crimps both wires at every intersection for general screening at medium apertures. Lock crimp uses a deeper crimp that locks the wires firmly at each cross point, holding the aperture stable under heavy vibration. Lock crimp suits coarser, more demanding screening duties.
What wire diameter does crimped screen mesh use?
Crimped screen wire is heavy, typically from about 1.6 mm for fine apertures up to 16 mm or more for primary scalping screens. As a rule, larger apertures need thicker wire to carry load and resist abrasion. Match the wire diameter to the aperture and the abrasiveness of the material.
What material is best for vibrating screen mesh?
High-carbon spring steel suits most abrasive screening, while manganese steel work-hardens under impact for the longest life on harsh primary screens. Galvanised mild steel is economical for less abrasive duties, and stainless steel is used for food, chemical or corrosive applications. Choose by abrasiveness and corrosion risk.
What aperture range is available in crimped mesh?
Crimped mesh covers roughly 2 mm up to 100 mm or more, spanning fine aggregate grading through to coarse primary scalping. The aperture is the clear opening between wires; heavier apertures are paired with thicker wire. Specify the exact cut point you need so the wire diameter is sized correctly.
