Wedge Wire Screen vs Woven Wire Mesh
A wedge wire screen is made of V-shaped wires welded onto support rods. It has very precise slots, does not clog easily and is easy to backwash. Woven wire mesh is stainless steel wire woven like cloth, in plain, twill and Dutch weaves, mesh 4 to 200. Choose wedge wire for precise, backwashable filter elements, and woven mesh for fine, flexible filtration.
Side by Side
| Wedge wire screen | Woven wire mesh | |
|---|---|---|
| What it is | V-shaped wire welded onto support rods, made into tubes, baskets and cylinders. | Stainless steel wire woven over and under like cloth. |
| Opening | Slot between two wires. Gap precision down to 0.005 mm. | Mesh 4 to 200 (openings per inch). Dutch weave for very fine filtration. |
| Resistance to blocking | Hard to block. The slot widens inwards, so a particle stops at the surface or passes straight through. | Depends on mesh and weave. Particles can lodge between the wires. |
| Cleaning | Easy to clean by backwashing. | Cleaned or replaced as a mesh element. |
| Form and size | Rigid tubes, 30–220 mm up to 2 m long (gap precision 0.005 mm); 400–1,200 mm up to 4 m long (0.03 mm). | Flat mesh or cloth, made into filter elements. Plain, twill and Dutch weave. |
| Materials | Made to order. | SUS 201, 302, 304, 304L, 316, 316L, 310, 310S. |
| Typical use | Hydrogenation backwash filter elements, feed filter elements for fractionation towers, custom screens. | Petroleum and chemical industry, water and sewage treatment, food and pharmaceutical industry, solid-liquid separation and screening. |
Choose Wedge Wire Screen When
- You need a backwash or feed filter element.
- You need precise slots that do not clog easily.
- You need a rigid, non-standard screen.
- You want to clean the filter by backwashing.
Choose Woven Wire Mesh When
- You need a filter mesh for gas or liquid.
- You need a specific mesh size or weave.
- You need very fine filtration (Dutch weave).
- You need heat and corrosion resistance in a flexible mesh.
Can You Use Both?
Yes. A woven mesh can be used as the fine filter with a wedge wire screen as the rigid support or coarse stage. Send us your flow, particle size and temperature, and we recommend a combination.
