Our rates

We charge by the square foot of the opening, not by the metre of cable. The rate covers the anchors, the cable, tensioning and the fitting, and the visit to measure it.

Invisible grill	₹220 / sq ft	Commercial and industrial openings
Invisible grill for windows	₹230 / sq ft	Windows and French doors

Pin-to-pin invisible grill	₹160 / sq ft	Budget builds, ledged openings, temporary sites

What is pin-to-pin fixing?

Pin-to-pin is the simplest way an invisible grill is held: stainless pins are anchored into the wall top and bottom, and the cable is run and tensioned directly between them. There is no aluminium track to buy or fit, which keeps the rate down. The cables carry the same load and use the same steel grades as our track-mounted grills, so it is a genuine fall-prevention barrier — just fixed by pins instead of channels. Ask for it when the budget leads or the opening already has a ledge to anchor into; the free site visit will confirm your wall takes the pins.

What moves the price

Grade: 316 costs more than 304 because of the molybdenum that stops rust
Cable thickness and spacing — closer spacing means more cable per foot
The opening: a tall French door or a curved bay takes more work than a standard window
The surface: hollow block and thin plaster need chemical anchors instead of plug anchors
Extras: emergency release panels, intermediate posts on long runs, and bird netting on the same ledge

How to compare two quotes honestly

Ask three things: the grade stamped on the cable, the spacing between runs, and whether the rate includes the anchors and the release hardware. A cheaper quote is usually a thinner cable, wider spacing, or 304 sold as marine grade. We give you the cable sample and the stamp so you can check ours the same way.

The average going rate in Chennai runs from about ₹130 to ₹350 a square foot. Anything well below that is worth a hard look at the specification before it is anything to do with the price.
