1. Product Description Perforated mesh is manufactured by punching a uniform pattern of holes — round, square, slotted, or decorative — into flat metal sheet or strip. The holes are arranged in staggered or straight-line layouts with precise, consistent openings and controlled open areas. Bolin supplies perforated sheets, coils, and perforated tubes in stainless steel and other metals for filtration, screening, acoustic, architectural, and machinery applications. 2. Available Materials Stainless Steel 304 / 316 / 316L / 2205 | Carbon steel | Galvanised steel | Aluminium | Copper | Titanium | Surface treatment options: acid-pickled, polished, powder-coated 3. Key Features •Precise, uniform perforation: stamping process ensures consistent hole size and spacing •Controllable open area: hole size and pitch designed to balance flow rate and structural strength •High strength: formed from a single solid sheet — no joints •Wide hole shape selection: round holes, square holes, slotted holes, fish-scale, and decorative patterns •Deep-processing capability: can be cut, bent, roll-formed into perforated tubes, filter baskets, and guards 4. Applications •Filtration and screening: filter plates, cartridge support cores, grain sieves •Architecture: curtain wall cladding, acoustic panels, suspended ceilings, balustrades •Machinery: protective guards, ventilation covers, heat dissipation panels •Mining and grain processing: vibrating screens, sizing screens •Food processing: baking trays, conveyor belts, drying racks •Acoustics: silencer baffles, noise barriers, acoustic enclosures 5.
