Perumal Safety Nets installs slim stainless-steel cable grill systems for apartment balconies, windows and suitable open spaces across Chennai. Each layout is measured for the opening and planned around the frame, cable spacing, tension and intended safety requirement.
Traditional bars can feel visually heavy in apartments with open views. Invisible grills use closely spaced, coated stainless-steel cables secured to a suitable frame or channel, creating a slim protective boundary with less obstruction.
Our site assessment checks opening dimensions, frame condition, anchoring locations, cable direction, spacing, access and exposure. Material grade and warranty must be confirmed in the written quotation for your selected system.

Confirm inspection availability for your apartment or property.
Invisible grills generally use coated stainless-steel cables secured to a frame or channel. Confirm the exact steel grade, cable construction, coating and diameter in your quotation.
They can be considered for suitable balconies, windows, staircase voids and other openings after checking dimensions, fixing surfaces and safe installation access.
The slim cables are intended to reduce visual obstruction. Visibility depends on cable thickness, spacing, direction, lighting and viewing distance.
Spacing should be selected for the intended safety use, opening and applicable site requirements. It must be agreed before fabrication and installation.
They can add a protective boundary when correctly specified and installed, but they do not replace responsible adult supervision or other appropriate safety measures.

If regular access is required, discuss it before quotation so an appropriate access arrangement can be assessed for that opening.
