Lianxin is a trusted manufacturer of Perforated Metal, offering precision-punched sheets made from a variety of high-quality materials including stainless steel, galvanized steel, aluminum, brass, and copper. Our Perforated Metal products are manufactured using advanced CNC equipment for tight tolerances and consistent quality, suitable for both industrial and decorative purposes.
Material Options and Thickness Range
We produce Perforated Metal using mild steel, stainless steel, galvanized sheets, copper, aluminum, and nickel alloys. Sheet thickness ranges from 0.1 mm to 10 mm, with the capability to punch holes as small as the sheet thickness (e.g., 0.5 mm thick sheet can be punched with 0.5 mm diameter holes).
Common Hole Shapes and Patterns
Our perforation options include round, square, slotted, hexagonal, diamond, rectangular, oval, triangle, cross, plum blossom, star-shaped, and custom irregular holes. Hole sizes typically range from 0.3 mm to 100 mm, with standard practice recommending that hole diameter not exceed sheet thickness.
