So R2\/T3.5 means 2.0mm round holes spaced at 3.5mm pitch on a staggered (60-degree triangular) pattern. This is the most common UK perforated sheet specification convention.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy choose galvanised over mild steel perforated sheet?\u003c\/strong\u003e\u003cbr\u003eGalvanised perforated sheet has a zinc coating applied before or after perforation, giving long-term corrosion resistance for outdoor and damp applications. Mild steel will rust in outdoor or unheated environments unless painted; galvanised steel will not. Choose galvanised for: outdoor screens, agricultural buildings, livestock pens, outdoor ventilation, marine-adjacent applications, animal enclosures, exterior architectural panels, and any application where the sheet will see moisture, weather or unheated conditions. Mild steel is fine for dry, indoor or paint-finished applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is galvanised perforated sheet used for?\u003c\/strong\u003e\u003cbr\u003eCommon applications include outdoor ventilation grilles, agricultural screens, livestock and animal enclosure panels, drying racks, sieves and filters for wet processes, exterior cladding panels, garden screens, fencing infill panels, water-strainer mesh, balcony screens, machine guards in damp workshops, and any outdoor or unheated location where rust resistance matters. The zinc coating provides 10-25+ years of outdoor service depending on environment.\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 galvanised perforated sheets.
