We perforate a wide range of round, square, slotted, decorative and even odd shaped perforations from a numerous metal sheets. The most common percentage of open area is between 30% and 50% although more extreme open areas are available depending on the perforation. Some times the percentage open area has to be kept lower for increased strength and flatness of the perforated metal sheet especially when galvanising.

The maximum sheet thickness, which we can perforate up to, is 25mm, the most common thickness range for balustrade infill, cladding panels is between 1.5mm and 3.0mm although heavier specifications do away with having to frame the sheets with something like edging profile which we also supply.

How to Make Perforated Sheets:
The sheet is fed to the machine by means of a Roller System Mechanism. The die is preloaded on the machine. On feeding the sheet, the upper section of the machine starts stroking. The sheet is perforated as per the die and is advanced by the amount of the perforated pitch set on the machine, with the next stroke of the slide. This cycle of feeding and perforating continues automatically.
