Framing & Track Mounting
Heavy-duty powder-coated aluminum tracks are bolted into the ceiling and floors using corrosion-resistant expansion fasteners.
Cable Threading & Tensioning
SS316 cables are threaded through nylon-insulated studs, manually tensioned to 400kg, and double-locked to prevent sagging.

Frequently Asked Questions
Everything you need to know about our safety solutions.
Are invisible grills safe for children and pets?
Yes, absolutely. The cables are set with a tight 2 to 3-inch gap, preventing children, toddlers, cats, and dogs from squeezing through. Because they are tensioned to over 400kg, they cannot be pried apart by hand.
Will invisible grills block my view or airflow?
No. The cables are only 2mm thin. From a distance of just 5–10 feet, they become practically invisible, preserving your natural skyline and balcony views while allowing 100% air ventilation.
How do invisible grills compare to traditional iron grills for fire safety?
Traditional MS iron grills are fixed, blocking exit points during emergencies. Vasantha Invisible Grills feature a quick-release fire safety lock option, allowing you to cut or release the cables in seconds using wire cutters during emergencies.
How long do these grills last in Chennai's high-humidity areas?
Our marine-grade SS316 invisible grills are engineered for high-salinity coastal areas like Pallikaranai, OMR, Velachery, and Adyar. They easily last 10+ years without rust, sag, or discoloration.
