How to Use the Wire Mesh Technical Calculator for Screen Parameter Conversion
Mesh ↔ Aperture Conversion
= Aperture + Wire Dia. (center-to-center spacing)
View Formulas
W = (25.4 / M) - dW = Aperture (mm), M = Mesh, d = Wire dia. (mm)
OA = (W / (W + d))^2 x 100OA = Open area (%), W = Aperture, d = Wire dia.

Material Corrosion Resistance Reference
Contains 2–3% molybdenum; chloride-resistant; suitable for seawater, acid, and pharmaceutical applications
General-purpose stainless steel; resistant to most chemicals; best value
High hardness, abrasion-resistant; not corrosion-resistant — dry applications only
Water and oil resistant; Shore A 65–90 adjustable; low noise
Low cost; suitable for slight moisture; not resistant to acids or alkalis
Quick Selection Guide
Significant corrosion (acid / seawater / salt spray)?
Choose SUS316L or polyurethane
High impact + dry coarse aggregate screening?
Choose 65Mn woven mesh
Fine particle dewatering / low blinding?
Choose mining welded slot screen
Noise reduction + long service life priority?
Choose polyurethane screen modules
Food / pharmaceutical / ultra-fine filtration?
Choose SUS304/316L precision woven mesh
