Why choose perforated mild steel sheet
Perforated mild steel combines strength with open area for airflow, light, drainage and visual effect. It is widely used for ventilation grilles, machine and plant guards, screens and sieves, balustrade and balcony infill panels, acoustic screening, vehicle and trailer panels, agricultural screens, sign blanks and decorative facade cladding. Smaller holes (such as R0.8/T1.5) give a finer, more solid appearance with higher strength; larger holes (such as R20/T27) give a greater open area for maximum airflow and through-vision.
Hole patterns available
All patterns are round-hole on a staggered 60° triangular layout, the UK industry standard. The pattern code reads as R (hole diameter) / T (pitch, centre-to-centre spacing).
