201 perforated mesh can make the product's mesh surface is relatively flat, the surface treatment is smooth and neat, and the material is more corrosion-resistant than the net hole precision. 201 perforated mesh is actually a kind of mesh formed by stamping 304 material on stainless steel by CNC machine according to a specific model. 201 perforated mesh can be deep processed by bending treatment and can be electrolytically polished for surface treatment. The surface treatment of electrolytic polishing treatment.

Regular 201 perforated mesh sheet size has 1m * 2m, 1.2m * 2.4m, 1m * 20m and other specifications, the thickness of the sheet can be produced between 0.5mm-20mm, the size of the aperture between 0.5mm-300mm can meet the user's custom needs. From the thickness of the plate and the size of the aperture can be seen, 201 perforated mesh material thickness and size is relatively thick and aperture is relatively large, not suitable for precision instruments, intelligent cars, dustproof mesh requirements, therefore, the stamping can not meet the requirements of its specific precision process, so the etching process is the first choice to meet the needs of high precision products on the dust, filtering and other mesh.
