Characteristics of perforated metal sheets: They are formed by stamping; their properties include bending resistance, aging resistance, rust resistance, and wide applicability; the mesh surface is flat, smooth, sturdy, and durable. Perforated metal sheets are made from metal plates, punched by stamping machinery. Specific materials include iron plates, aluminum plates, stainless steel, copper plates, and nickel plates. Iron plate materials include cold-rolled iron plates, hot-rolled iron plates, galvanized iron plates, and manganese steel plates; aluminum plate materials include 1050, 1060, 1070, 1100 and other 1-series aluminum plates, 3003, 3004, 3104 and other 3-series aluminum plates, 5005, 5052, 5083 and other 5-series aluminum plates; stainless steel materials include 201, 304, 316, 316L, 409, 430, etc. Perforated metal sheets have many applications in industry.
Products are used in construction engineering, food processing, petrochemicals, etc. Hole types include round holes, square holes, oblong holes, floral holes, and various combinations of hole types. Round hole mesh is the most commonly used perforation type. Perforated metal sheets can be produced in rolls or sheets, and come in various specifications. They can also undergo further processing. Their main applications include: mining, pharmaceuticals, grain screening, indoor sound insulation, sound absorption, grain storage ventilation, and machinery protection. Examples include stainless steel fruit baskets, food covers, fruit plates, and other kitchen utensils; shelving and decorative display stands in shopping malls; ventilation and breathable mesh for grain storage; and drainage and filtration mesh for football field lawns. Perforated metal sheets are also widely used in the electronics industry, such as dustproof and soundproof covers for audio equipment. Their product characteristics include: easy processing and forming; ability to be painted or polished; easy installation; diverse appearances; various sheet thicknesses; multiple choices of hole diameters and arrangements; good sound absorption; light weight; long service life; and precise dimensions. Perforated metal sheets are also widely used in various industries such as chemical machinery, pharmaceutical equipment, food and beverage machinery, cigarette machinery, harvesters, dry cleaning machines, ironing tables, soundproofing equipment, refrigeration equipment (central air conditioning), speakers, handicrafts, papermaking, hydraulic components, and filtration equipment.
