Perforated metal is made by punching holes into metal sheets or coils. Common materials include low carbon steel, galvanized steel, stainless steel, aluminum, copper, brass, and nickel. Hole pattern, hole size, sheet thickness, and panel dimensions are made to order.

Our CNC punching lines handle hole diameters from 0.3 mm to 100 mm. On thin material, the hole diameter can be equal to the sheet thickness. For example, a 0.5 mm sheet can be punched with 0.5 mm holes. Sheet thickness ranges from 0.2 mm cold rolled coil to 10 mm plate, with standard plate sizes up to 1.5 × 3 m.

Available patterns include round, square, rectangular, diamond, hexagonal, triangular, cross, plum, star, and irregular holes. We also produce custom patterns from customer drawings.

Surface options include PVDF, PVC coating, spray painting, polishing, oxidation, and galvanizing. The finish is selected for indoor, outdoor, or corrosive environments.

Typical uses include acoustic panels, wall and ceiling finishes, stair and balcony cladding, machine guards, speaker grilles, kitchen baskets, shelving, display platforms, filtration equipment, and components for chemical, pharmaceutical, and food-processing machinery.
