So R20\/T27 means 20.0mm round holes spaced at 27.0mm pitch on a staggered (60-degree triangular) pattern. This is the most common UK perforated sheet specification convention.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is perforated mild steel used for?\u003c\/strong\u003e\u003cbr\u003ePerforated mild steel sheet is used across construction, industrial, architectural and decorative applications - including ventilation grilles, machine guards, screens, sieves, vehicle and trailer panels, agricultural use, sign blanks, balustrade infill, balcony screens, acoustic panels, and as decorative facade panels. The choice of hole size and pitch depends on the open-area required and visual look you're after.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thicknesses are available in R20\/T27 pattern?\u003c\/strong\u003e\u003cbr\u003eThis R20\/T27 pattern is available in: 2mm, 3mm. Thicker sheets give greater rigidity and load-bearing capacity but reduce open-area visibility. Choose the thickness based on your application - lighter gauges for decorative screens, heavier for structural or guarding applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat's the delivery lead time?\u003c\/strong\u003e\u003cbr\u003eLead times are currently 3-5 working days for perforated mild steel sheets.
