Overview
Two mesh families,
one engineering decision
Woven mesh and knitted mesh solve different problems. Woven mesh gives you a stable, repeatable opening — the right answer when retention and flow have to be predictable. Knitted mesh gives you porosity and the ability to deform into a shape — the right answer when the part has to fit a stack or absorb load. The first thing BVK does on any enquiry is work out which of the two your component actually needs.

Capability
What a precision mesh
component involves
Six decisions stand between an enquiry and a part that works. BVK makes all six in-house, which is why they stay consistent from the first sample to the hundredth batch.
Material Selection
Alloy chosen against corrosion, temperature, conductivity and cost.
Inspection
Light-box and video inspection against a documented control plan.
Forming
Crimping, corrugation, flattening, slitting and laser cutting to final shape.
Treatment
Annealing, degreasing, coating or plating to change how the mesh behaves.
Mesh Geometry
Aperture, wire diameter, knit density and weave pattern set the performance.
Documentation
Traceability records, control plans and PPA packs for qualification.
Selection guide
Choosing between
woven and knitted
There is no universally better mesh. There is only the one that suits your duty. This is the shortlist our engineers work through before recommending either.
- Need a defined, repeatable opening size — choose woven
- Need high porosity and low weight — choose knitted
- Part must hold a flat, stable geometry — choose woven
- Part must conform to an irregular or layered shape — choose knitted
- Filtration with a stated retention rating — choose woven
- Elastic element, demister or compressible layer — choose knitted
