The production process of stainless steel expanded metal mesh involves punching and stretching metal sheets using specialized machinery (expanded metal mesh punching and shearing machines) to create a mesh-like sheet.
Its production must comply with relevant standards. For example, GB/T 11953-89 specifies the aperture range, plate thickness, and material requirements for stainless steel expanded metal mesh; HG/T 21559.3-2005 supplements this with specifications for corrosion resistance and mechanical strength testing (applicable to chemical environments).
Common aperture types for stainless steel expanded metal mesh include diamond-shaped holes and hexagonal holes. Examples of aperture sizes include 8mm*16mm, 10mm*20mm, 13mm*25mm, 20mm*40mm, 30mm*60mm, 40mm*80mm, 50mm*100mm, 50mm*150mm, and 80mm*200mm. The sheet thickness production range is 0.5-8mm, with common choices being 1.0mm-4.0mm; long pitch (TB) is 12.5-200mm, and short pitch (TL) is 5-80mm. Mesh dimensions are 600-4000mm in length and 600-2000mm in width, with widths up to 2m and lengths under 5m customizable. Model naming examples include SBW-304-20×40-1.5 (Shenbao brand, 304 stainless steel, 20×40mm diamond-shaped holes, 1.5mm sheet thickness) and DL-316L-15×30-2.0 (Delong brand, 316L stainless steel, 15×30mm diamond-shaped holes, 2.0mm sheet thickness).
