Sintered mesh
A rigid, porous laminate.
Multi-layer woven mesh, sintered into a rigid porous laminate: precise pores, high strength and a filter that can be cleaned and reused.
Sintering bonds layers of woven wire cloth at their contact points to form a rigid, porous laminate. Fine cloth provides the filtration layer, while coarser layers support it and help it retain its geometry under the specified load.
The protection, filter, distribution and support layers are selected to suit the required pore size, permeability and stiffness. Graded pore structures can increase dirt-holding capacity and extend cleaning intervals, depending on the contamination and cleaning method.
Averinox produces and supplies sintered laminates as panels, discs, cones, cylinders and complete welded elements, with application analysis and material advice. Sub-micron ratings down to 0.5 µm are available for polymer, gas and high-purity service; the achievable rating is confirmed per application.
Applications
- Polymer melt filtration (high-viscosity, high-pressure)
- Hot gas and catalyst recovery filtration
- Hydraulic and lubrication oil cleaning
- Fluidising plates and spargers in powder processing
- High-purity steps in food, pharma and hydrogen systems
Features & benefits
- Sub-micron lay-ups (to 0.5 µm) available after technical confirmation
- Rigid support for the filter layer under specified ΔP and pulsation
- Cleanable and reusable where contamination and material allow
- Weldable into cartridges, baskets, cones and custom elements
- Graded structures for long on-stream time
Specifications
spec.json ↗| Property | Value |
|---|---|
| 2–6 layers of woven mesh, sintered under heat and pressure into one rigid laminate | |
| 2 µm – 200 µm absolute standard; sub-micron lay-ups to 0.5 µm confirmed per application | |
| Typically 1000 × 1000 / 1200 × 1200 mm; cut, rolled and welded parts on request | |
| Uniform or graded (coarse-to-fine) for higher dirt-holding capacity | |
| Backflushable and regenerable (ultrasonic, chemical, pyrolysis) | |
| High differential pressures; temperatures up to ~600 °C in 316L, higher in special alloys |
Materials & variants
Standard laminates are sintered in 316L; 904L and nickel alloys such as Inconel™, Hastelloy™ and Monel™ cover aggressive chemistry and high temperature. Lay-ups are documented per order, with material certificates and pore-size verification on request.

Frequently asked questions
Sintered mesh or sintered powder: which one do I need?
Sintered mesh is an option where permeability, mechanical support and backwashing matter. Sintered powder is also used for fine filtration. We compare the required rating, contamination and cleaning cycles to assess the suitable medium and lifetime cost.
Can sintered elements be repaired or re-rated?
Elements can usually be cleaned and re-welded if the laminate itself is intact. We assess returned elements and advise honestly whether cleaning, repair or replacement is the economical option.
What does an absolute rating of 10 µm actually mean?
An absolute rating of 10 µm refers to the maximum particle size that can pass under the stated test conditions. Specify the required rating and test method, particularly when protecting downstream equipment. Pore-size verification is available on request. A nominal rating describes retention as a percentage under its stated conditions.
Can you cut and weld laminate panels to our drawing?
Yes. Standard panels of 1000 × 1000 and 1200 × 1200 mm are cut, rolled and welded to size into discs, cones, cylinders and complete elements. Weld zones are engineered so the pore structure next to the seam keeps its rating.
How many cleaning cycles does sintered mesh survive?
There is no fixed number: it depends on the contaminant and the cleaning method (backflush, ultrasonic, chemical or pyrolysis). The laminate itself outlasts many cycles as long as differential pressure stays within design limits. We assess used elements and tell you honestly when cleaning stops paying off.
