Welded and woven wire mesh look similar at a glance, but they are made in fundamentally different ways and behave differently in use. The choice usually comes down to whether you need a rigid structural panel or a flexible screen with controllable, often very fine, openings.
What is welded wire mesh?
Welded wire mesh is produced by laying straight wires in a grid and resistance-welding them where they cross. Each intersection becomes a fixed joint, so the finished sheet holds its shape, resists distortion and carries load across the panel. It is commonly supplied in flat sheets or rolls and in a range of wire gauges and square openings. Because the geometry is locked in by welding, welded mesh delivers consistent square apertures and is straightforward to fabricate into cages, trays and frames.
What is woven wire mesh?
Woven wire mesh is made on a loom-like process where warp and weft wires are interlaced and, in many weaves, crimped to lock the wires in position. Nothing is welded, so the cloth remains flexible and can be drawn down to extremely fine apertures, including micron-scale openings used in precision filtration. Weave patterns such as plain, twill and Dutch weave let manufacturers tune aperture, open area and particle retention for specific separation tasks.
Side-by-side comparison
| Criteria | Welded mesh | Woven mesh |
|---|---|---|
| Construction | Wires fused at each intersection | Wires interlocked / crimped, not welded |
| Rigidity | High, holds shape as a panel | Flexible, drapes and conforms |
| Opening accuracy | Precise, consistent square apertures | Very fine apertures achievable, tunable by weave |
| Strength behaviour | Strong, stable structure; joints can fail if over-bent | Strong in tension; relies on crimp rather than welds |
| Typical use | Fencing, animal cages, mesh reinforcement, infill panels | Filtration, sieving, fine screening, separation |
| Cost | Typically lower for heavier gauges | Varies with fineness; fine weaves cost more |
Which should you choose?
- Choose welded mesh when you need a rigid, load-bearing or shape-holding panel for fencing, cages, partitions, shelving or reinforcement.
- Choose woven mesh when you need fine, accurate apertures and flexibility for filtration, sieving, screening or any task driven by particle size.
- Consider gauge and coating separately from construction, since both types are available in galvanised, PVC-coated and stainless variants.
If the job is about structure, lean welded. If it is about separation and fine, controllable openings, lean woven.
