2 layer sintered wire mesh is a popular kind of stainless steel sintered mesh for filtration and aeration applications.
We know single layer sintered wire mesh has non fraying mesh: no wire migration while cutting, abrasion, folding and pleating. And the pore shape and size of the sintered wire mesh are fixed as the wires are diffusion bonded with each other and the mesh becomes a whole part.
2 layer sintered wire mesh for better performance
2 layer sintered wire mesh has the same single layer property, while it can also combine the property of the 2 layer mesh and give a comprehensive better performance. The better performance is often in the strength. One layer functions as the main working layer while the other is the supporting or reinforcing layer.
