Stainless steel wire mesh, also known as stainless steel woven wire mesh, stainless steel filter screen, stainless steel wire cloth or stainless steel screen, is woven by using wire weaving machines in the dust-free and constant-temperature workshops. The raw materials used for wire weaving purposes are quality standard stainless steel wires, whose steel grade could be AISI304, 304L, 316 and 316L, etc. These quality wires are made using the wire drawing machines, in which the wire drawing process to reduce the wire cross-section to a desired diameter is performed at specific elevated temperatures. The weaving types of stainless steel wire mesh mainly fall into plain weave, twill weave, plain dutch weave, twill dutch weave, three-shaft weave, five-shaft weave and reverse dutch weave. A different weaving type is suitable for a different purpose. Stainless steel wire mesh is generally characterized by its precise structure, uniform meshes, nice filter fineness, wear resistance, high-temperature resistance, resistance to acid and alkali and corrosion prevention. Stainless steel wire mesh could serve the purpose of screening, filtration and shielding, and is ideal for a number of fields, including medicine, electronics and aerospace.
Mesh count (mesh)
means the number of mesh openings per inch on woven wire mesh, like stainless steel woven wire mesh. The more the number of mesh openings per inch, the larger the mesh count (mesh), the smaller the mesh opening size, so the finer the sieve size, and vice versa. For instance, 100 mesh count (mesh) means 100Nos mesh openings per inch. If the specification is 100X100X0.1mm, then 100 means 100 mesh count (mesh).
Wire Diameter
Generally stainless steel wire mesh is woven from round wire. Wire diameter means the cross-section diameter of round wire. The mesh wire falls into weft wire and warp wire. As far as stainless steel wire mesh is concerned, wire diameter is commonly designated using millimeter (mm) and inch (“). Internationally, the common wire gauges for measuring the diameter of wire are expressed as AWG (American system), BWG ( Birmingham system) and ,SWG (British system). Please refer to the relevant wire diameter cross-reference table.
Computing Formula to Determine Percent Open Area of Stainless Steel Wire Mesh
The percent open area of stainless steel wire mesh means the ratio of the area of the openings to the total area expressed as a percentage. The area of the openings is virtually the active filtration area of stainless steel wire mesh.
In terms of plain weave mesh, percent open area =〔Opening/(Opening + Wire Diameter)〕2 X100
For example, 100meshx 0.1mm, percent open area = 〔0.154/(0.154 + 0.1)〕2 X100=36.76
Conversion Formulae of Wire Diameter, Opening and Mesh Count
1)Conversion formulae to determine various parameters in stainless steel wire mesh: 25.4/(Wire Diameter + Opening)=Mesh Count
For example, 100meshX0.1mm Wire Diameter, its opening is 25.4/100-0.1= 0.154mm.
2）In terms of stainless steel dutch wire mesh, because that warp wires differ in diameter from weft wires, and the lengthwise mesh count is also different from the width wire mesh count, the relevant parameters need computing separately.
Weight Calculation Formulae
1)Weight calculation formulae of stainless steel wire mesh: Wire Diameter X Wire Diameter X Mesh Count X 0.5 = Weight Per Square Meter
For example, stainless steel wire mesh 100MeshX0.1mm Wire Diameter, weight per square meter= 0.1 X 0.1 X 100 X 0.5 = 0.5kgs/sqm.
2)In terms of stainless steel dutch wire mesh, because that warp wires differ in diameter from weft wires, and the lengthwise mesh count is also different from the widthwise mesh count, the weight per square meter needs computing separately, and then add the two figures, namely the weight per square meter in the lengthwise direction and the weight per square meter in the widthwise direction, together, finally the sum of aforesaid two figures should be divided by two, and so you get weight per square meter of stainless steel dutch wire mesh.
For example, 30meshX150mesh, wire diameters are 0.25mmX0.18mm, then weight per square meter=(0.25×0.25x30x0.5+0.18×0.18x150x0.5)X0.5= 1.68375
