Punching Mesh is a functional mesh material created by punching regular holes into metal or non-metallic sheets. Common materials include stainless steel, galvanized steel, aluminum, and PVC. The surface can be painted or electroplated for corrosion protection to enhance durability. Perforated metal is available in a variety of shapes, including round (the most widely used), square, plum blossom, diamond, and special-shaped holes. Customizable apertures range from 0.4-100mm and thicknesses from 0.2-20mm. It combines lightweight, high strength, ventilation and light transmission, sound absorption and noise reduction, and anti-slip and wear resistance. This material is widely used in construction (such as exterior wall decoration, ceiling sound-absorbing panels, and stair anti-skid plates), industrial equipment (such as machinery protective covers and mine screen filters), household items (tables, chairs, lamps, and fruit trays), and transportation infrastructure (such as highway noise barriers and lawn water seepage filters). Its aesthetic appeal, environmental friendliness, and cost-effectiveness meet multifunctional needs.
