The stainless steel mesh, scientifically known as dense mesh, is also referred to as Halan cloth in regions south of the Yangtze River or abroad. It is made from high-quality stainless steel wire. The main characteristics are that the diameter and density of the warp and weft wires have a significant contrast, which results in a noticeable improvement in the thickness, filtration precision, and service life compared to square hole mesh. Its filtration precision cannot be achieved by square hole mesh.
