We perforate a wide range of round, square, slotted, decorative and even odd shaped perforations on special request. Percentage open area, the most common percentage 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 sheet especially when galvanising.
Our maximum material thickness, which we can perforate up to, is 25mm, the most common thickness range for balustrade infill, cladding panels etc. 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
The maximum width we can perforate up to is 2mt, the preferred maximum is 1.5mt.
The maximum length we can perforate up to is 6mt, the preferred maximum is 4mt.
The most common material types are mild steel, Pre-galvanised mild steel, stainless steel, aluminium, brass and some types of plastics.
Due to recent investment, small quantity uncommonly asked for specifications can now be economically catered for.
Perforated metal is used in many applications such balustrade infill, acoustics, security screens, air-condition units, radiator covers, screening, and display units.
