Wedge wire screens use shaped profile wires, often with a V-like cross-section, joined to transverse support rods. The surface creates long, controlled slots rather than woven openings or punched holes. Cylinders, flat panels, baskets, and intake screens are common forms in water treatment, process filtration, pulp and paper, food processing, and other separation duties.
Why profile-wire slots are different
The slot is commonly narrower at the working surface and opens inward between support rods. This geometry can help reduce bridging and supports cleaning in suitable applications. Actual performance still depends on slot width, profile geometry, support spacing, material, flow direction, pressure, contamination, and the complete equipment design.
The wire mesh classification guide places wedge wire alongside woven mesh, perforated sheet, and other separation products, but its construction and supply forms are distinct.
Build the specification around the process
State material grade, slot width, profile-wire and support-rod geometry, screen diameter or panel size, length, end connections, open area, flow direction, required finish, and inspection requirements. A nominal slot by itself does not define a complete screen. For a cylinder, connections and roundness may be as important as the slot; for a panel, flatness and support design may control installation.
Use the RFQ guide to make the process, geometry, and documentation assumptions visible before quotation. The receiving inspection checklist then provides a controlled handover record.
Selection and acceptance
Select by the material to be retained, fluid properties, cleaning approach, pressure or load, corrosion exposure, and downstream use—not only by a product name such as “Johnson screen.” Confirm slot measurement method, product identity, surface condition, connections, roundness or flatness, packing, and traceability where applicable.
