If you are buying perforated sheet in Noida or Delhi NCR, the quick answer is: choose MS (mild steel) for indoor, dry or paintable applications, GI (galvanised) for outdoor and semi-outdoor use at a fair price, SS (stainless steel) for premium finish, hygiene or corrosion-critical jobs, copper or brass for decorative and heritage work, and aluminium when you need light weight for facades, ceilings or HVAC. This guide from Garg Industrial Mesh, Sector 9 Noida, compares all six so you can specify correctly without overspending.
What is a perforated sheet?
A perforated sheet is a metal panel punched with precise holes - round, square, slotted or decorative. It is used for sieves, guards, facades, ventilation, acoustic panels and walkway gratings. The material choice decides cost, weight, colour and how well it resists rust.

When to choose MS perforated sheet
MS is the cheapest and strongest option, but it rusts if left unprotected. It is right for indoor, dry or paintable applications - machine guards, vibrating screens, sieves and structural panels that will be painted or powder-coated.
When to choose GI perforated sheet
GI is mild steel with a hot-dip zinc coat, giving solid rust resistance at a moderate price. It is the workhorse for outdoor and semi-outdoor use - ventilation grilles, walkway gratings, outdoor sieves, agricultural screens and noise barriers. If your sheet sees weather but you do not need the premium price of stainless, GI is the sweet spot.
When to choose SS perforated sheet
SS (grades 202 and 304) is the premium choice - corrosion-resistant, food-safe and with a clean architectural finish. Use it for facades, sun louvres, balustrade infill, food-grade screens, filtration and any application where appearance or hygiene matters. It costs the most among steel options but lasts the longest and looks the best.
When to choose copper perforated sheet
Copper perforated sheet is chosen for decorative cladding, temple and heritage architecture, and EMI/RFI shielding. It develops a natural patina and stands out from steel. Garg Industrial Mesh supplies copper perforated sheet cut to size in Noida.
When to choose brass perforated sheet
Brass perforated sheet suits ornamental screens, nameplates, furniture inlays and warm-tone architectural detailing. It resists corrosion indoors and in semi-outdoor use and is cut to your panel size.
When to choose aluminium perforated sheet
Aluminium perforated sheet is the light option for building facades, false ceilings, HVAC grilles, acoustic panels and sunscreens. It is easy to cut, powder-coat and install where weight savings matter.
