{"product_id":"perforated-galvanised-steel-sheet","title":"Perforated Galvanised Steel Sheet","description":"\u003cp\u003ePerforated galvanised steel sheet from Rackerman, available in \u003cstrong\u003e9 hole patterns\u003c\/strong\u003e from R2\/T3.5 to R20\/T27, in thicknesses of 0.7mm, 0.8mm, 1mm, 1.5mm, 2mm and sheet sizes of 2 x 1m and 2.5 x 1.25m. Pre-galvanised (zinc-coated) steel gives strong corrosion resistance, making it the right choice for outdoor, damp and exterior applications where uncoated mild steel would rust. Select your exact hole pattern, sheet size and thickness from the options above – every combination is a stocked specification supplied across the UK.\u003c\/p\u003e\n\u003ch2\u003eWhy choose perforated galvanised steel sheet\u003c\/h2\u003e\n\u003cp\u003ePerforated galvanised 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 R2\/T3.5) 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.\u003c\/p\u003e\n\u003ch2\u003eHole patterns available\u003c\/h2\u003e\n\u003cp\u003eAll patterns are round-hole on a staggered 60° triangular layout, the UK industry standard.
