SS 316 Invisible Grill in Chennai

All three look identical on the day of fitting, which is exactly why cheaper quotes are so tempting. The difference is chemistry: SS 316 contains molybdenum, which is what resists chloride — the salt in coastal air and rain.

SS 304 performs well inland but tends to develop tea-staining and pitting within a few years near the coast. SS 202 is the lowest grade commonly offered and can show rust marks on a Chennai balcony within a single monsoon.

Homes in Besant Nagar, Thiruvanmiyur, ECR, Neelankarai and the harbour side get constant salt exposure, but even inland areas like Anna Nagar and Ambattur see high humidity for most of the year.

Corrosion rarely starts in the middle of a cable — it starts at the crimp and where the cable enters the track. That is also the point that carries the load, so a rusting grill loses strength before it looks bad.

Every quote we issue names the steel grade, cable thickness and spacing, so you can compare like with like against other dealers. We do not swap grades between quote and fitting.

Cleaning is simply a wipe with a damp cloth. No painting, no annual anti-rust coating, and no re-welding, which is where iron grills quietly cost you more over ten years.
