Mesh
The mesh number of metal braid is the number of holes, which is the number of holes per square inch. The larger the mesh number, the smaller the aperture. In general, the number of mesh × aperture (micron number) = 15000. For example, the aperture of a 400-mesh screen is about 38 microns; the aperture of a 500-mesh screen is about 30 microns. Due to the problem of opening ratio, that is, because of the difference in the thickness of the wire used in weaving the net, the standards of different countries are also different. Currently, there are three types of standards: the American standard, the British standard and the Japanese standard.

Detail
Metal wire screens are not allowed to have serious weaving defects, such as holes, half-cut wefts, serious dense channels, large cracks, severe curling of the mesh surface, out-of-tolerance mesh inclination, severe mechanical damage, and the interweaving firmness of warp and weft does not meet the requirements. wait. However, general weaving defects are allowed, such as single broken wire, nested weft, back nose, small loose thread, small jumper, wrong twist, slightly uneven mesh surface, slight curling, point-like oil stains, small debris woven into the mesh and mild wavy edge etc.

From the classification of materials, it can be divided into: barbed wire mesh, stainless steel wire mesh, copper wire mesh, rare metal mesh, etc. According to the classification of weaving method, it can be divided into: plain weave mesh. Twill weave mesh. From the classification of production process, it can be divided into: woven mesh, welded mesh, punched mesh, punched mesh.
