Most perforated metal is produced as round holes. Why? Round hole punches are easier to make and maintain resulting in greater efficiency and less expense than other hole shapes. The dies and blocks are easier to manufacturer, last longer, and produce stronger patterns than other hole shapes.
Standard perforation patterns include 60, 90 and 45 degree orientation.
Technical capabilities of perforated metal:
Perforation size: 0.5mm - 150mm. (additional Perforation sizes are available on request)
Sheet Thickness: Popular thickness: 0.4mm - 12mm. QingFa can perforate up to 25mm thick on special request/order
Sheet sizes: Standard sizes include 2mx1m, 2.44mx1.22m, 2.5mx1.25m and3mx1.5m. Sheets 4mx2m are perforated on our larger machines. Longer lengths up to 6m perforated by specific request.
Percentage open area: All open areas are possible however the standard tooling tends to be between 20% and 60% open area
materials including of :stainless steel sheets, aluminium sheets, steel sheets, galvanized steel and brass etc.
