2 Layer Sintered Stainless Mesh is a new type of filter material with high mechanical strength and overall stiffness structure. 2 Layer Sintered Stainless Mesh is made by special techniques such as lamination and vacuum sintering on multi-layer wire mesh. The staggered mesh forms a uniform and ideal filtering structure, which not only overcomes the shortcomings of low strength, poor rigidity and unstable mesh shape of ordinary metal mesh, but also achieves reasonable matching and design of aperture, permeability and strength.
