Woven mesh basics
Open area percentage
Ratio of open area to total surface viewed at 90°, in %. Shows how easily light, air or objects pass through.
Overall thickness
Approximate thickness measured at wire crossings — the thickest part of the mesh.
Weave type
How the warp and fill wires are shaped before weaving; depends on spacing and wire diameter.
Opening aspect ratio
Ratio of the long side to the short side of the opening (1:1, 2:1, 4:1, 6:1).
Max. passage diameter
Diameter of the largest sphere that can pass through an opening.
Surface weight (kg/m²)
Approximate weight per m² based on carbon steel; actual weight depends on the metal.
