All our filtration products are made from a perforated metal sheet. These perforations are made with our WaterJet technology and are highly accurate and consistent. In applications with high differential pressure or mechanical stresses, these perforations are fixed and will not widen.
Wedge wire uses a welded support construction to strengthen and stabilize their product. These welding points may break down when significant force is exerted. When the wires shift, the filtration rating is no longer obtained and unwanted particles will pass through the filter. The same problem occurs with wire mesh elements.
