Design & Install Considerations
Practical information for your consideration.


Architectural Mesh
If the mesh is being used externally for aesthetic purposes, to minimise tea staining please evaluate if the mesh is to be pickled, passivated and electropolished.

Care & Maintenance

Care & Maintenance
Stainless steel is a low maintenance material, but not maintenance free. Regular cleaning is recommended to prevent the build-up of contaminants such as dirt and salt. Refer to our CARE page for further information.

Stainless Steel Window & Door Mesh - More Information

Stainless Woven Mesh Terminology

Mesh – The number of openings per lineal inch.
SWG – Standard wire gauge
Aperture– The distance between two adjacent wires
Diameter– The thickness of the wire before weaving
Pitch– The distance between the middle point of two adjacent wires or the sum of the aperture width and the wire diameter.
% Open Area– The ratio of the area of the aperture to the area of the mesh expressed in percentage terms
Warp– All wires running lengthwise of the cloth as woven
Weft– All wires running across the cloth as woven

Stainless Woven Mesh Formulas

Calculating the aperture
1. Count of a convenient number of apertures (N)
2. Measure the length covered by the N apertures (L)
3. Measure the wire diameter (D)
4. The average aperture


Working example of calculating the aperture of 6/20 woven wire mesh
1. Number of apertures counted                         N = 6
2. Length covered by apertures centre to centre  L = 25.4mm
3. Diameter of wire                                           D = 0.9mm
4. Aperture


The woven wire is identified as 3.33mm aperture / 0.9mm diameter
Mesh Count
If the aperture and the diameter are known the mesh count can be determined


Percentage Open Area


The mesh has a 62% open area

Micron Conversion
Micron (micrometer) is a unit of measure, in which usually only fine mesh under 1mm is referred to. A micron us a thousandth of a millimetre.

In this example 325/48.5, 0.043mm aperture, 0.035mm diameter is used.


Plain Weave


The most common and simplest weaves.Each warp wire (wire running parallel to the length of the cloth) passes alternatively over and under the wires running transversly through the cloth at 90 degree angles.
Intercrimp Weave


Has extra crimps in warp and weft wires between intersections.

Lock Crimp Weave


Is produced with pre-crimped wire. Lock crimp weave is stabilised by a notch or bump at the wire intersections.

 Twill Weave


Is Produced by passing each fill wire alternatively over and under two warp wires.
