Sintered square plain woven wire mesh is produced by sintering several layers of square plain woven wire mesh. The presence of large open area percentage in the mesh layers offers good permeability properties and small flow resistance. It is made in the various combinations of plain square woven mesh layers to obtain specific flow and filtration properties. This kind of mesh is ideally used in polymer production and different types of fluid filtration applications. It is possible to sinter multiple layers of woven mesh together to create products that are extremely thick and are used as fire and explosion resistors. In addition of thickness in inches, the mesh offers good flow properties.
