Clean water has a mesh.
Filtration is a quiet discipline: when it works, nobody notices. For it to work, it needs woven or knitted stainless steel wire.
- Whether drinking-water treatment or a sewage plant: filtration needs wire mesh that works wet, under load and permanently — without corroding.
- In petrochemicals, demisters made of knitted wire separate oil and other media — invisible in the process, but process-critical.
- Food production runs on acid-resistant stainless steel mesh: even fruit acid makes ordinary steel unusable.
- The best-known filter in the world stands in your kitchen: the dishwasher strainer made of stainless steel wire.
Filtration is a quiet discipline: when it works, nobody notices. For it to work, it needs a material that is simultaneously permeable and stable, fine and load-bearing, permanently wet yet corrosion-free. That material is woven or knitted stainless steel wire.
Where wire mesh filters and separates.
Water treatment
Screens and mesh in drinking-water and sewage processes — continuous operation in a wet environment, with stainless as the baseline requirement.
Process industry / demisters
In refinery and chemical processes, knitted-wire packages separate droplets from gas streams — the porous structure is the key: high surface area, defined throughput.
Food
Conveyor belts made of acid-resistant stainless steel mesh transport fruit and food through production — fruit acid tolerates no compromise on material.
Household
Dishwasher filters, extractor-hood knit, coffee-machine strainers — everyday proof of the same technology.
Woven or knitted?
Woven mesh (warp and weft) delivers defined, precise apertures — ideal for screens, filter grades and smooth passages. Knitted mesh (circular knitting machine, porous tube) delivers volume and surface area — ideal for separators, damping and flow-through. Material choice follows the environment: 1.4301/304 as the base, molybdenum-alloyed 1.4404/316 for more aggressive media, titanium-stabilised and heat-resistant grades for special cases.
Why BenderWire.
Within the group, the whole chain comes from a single source: the individual wire from the fine-wire mill, the woven and knitted mesh from downstream processing. Whoever draws the wire that becomes the mesh can factor filter performance in right from the melt analysis.
Frequently asked questions.
Which stainless steel for filters in water contact?
The base is 1.4301/304; for chloride- or acid-loaded media, molybdenum-alloyed grades such as 1.4404/316L.
What is a demister?
A package of knitted wire mesh that separates liquid droplets from gas streams in process plants — standard in petrochemicals and chemicals.
Why acid-resistant mesh for food?
Because even the natural acid of fruit attacks ordinary steel — food conveyor belts need acid-resistant stainless steel.
