Many newer apartment buildings and villas are designed with clean, grille-free facades, and homeowners are often reluctant to add visible iron grillwork that changes the building's exterior look or voids an RWA's design guidelines. Invisible grills solve this by using thin, high-tension SS304 wire ropes spaced roughly 4 inches apart, strong enough to stop a fall but visually near-transparent from a distance.
Each wire is individually tensioned using a turnbuckle system, anchored into the slab above and below the opening. This is a different technique from netting: fewer, stronger tension points rather than a woven mesh, which is why invisible grills suit larger openings like floor-to-ceiling windows or glass balustrade balconies where a net's mesh pattern would look out of place.
Invisible grills are particularly common in villa compounds, high-rise glass balconies, and staircases where the client wants a completely unobstructed view but still needs a code-compliant fall barrier, especially for resale or rental properties where buyers expect a premium finish.
Because the wires are exposed to weather, we use marine-grade stainless steel rather than galvanised iron, which would rust and streak the facade within a year or two in most Indian climates.

|---|---|---|
| Standard window (per running ft) | ₹180 – ₹280 | SS304 wire, turnbuckle tensioned |
| Balcony / balustrade opening | ₹250 – ₹400 per running ft | Depends on height and number of wire rows |

Prices are indicative; your exact quote depends on site inspection, height and access.
Frequently asked questions
Is invisible grill as strong as a normal iron grille?+
Tensioned SS304 wire at 4-inch spacing is rated for equivalent fall-safety load to a standard iron grille, though it is not designed to stop very small pets from squeezing through — netting suits that need better.
Does the wire rust or sag over time?+
Marine-grade stainless steel resists rust for years even in coastal climates, and our turnbuckle tensioning system allows periodic re-tightening if wires loosen slightly.
Can invisible grills be used on large glass balconies?+
Yes, this is one of the most common use cases, since a woven net's grid pattern is visually heavier against floor-to-ceiling glass than spaced wire.
How is pricing different from balcony netting?+
Invisible grill is priced per running foot of wire span rather than per sq.ft of mesh, and is generally a higher-cost option due to the SS304 material and turnbuckle hardware.
