316 Grade Invisible Grill — Duvvada
Safety, aesthetics, and long-term value — these three pillars define every GCM invisible grill installation in Duvvada.
As Vizag Suburbs's most trusted manufacturer of anti-rust 316 Grade Stainless Steel invisible grills,
GCM Invisible Grills serves families, apartment complexes, villas, and commercial buildings across Duvvada
with a product engineered to last a lifetime.
Unlike traditional iron grills that obstruct views and create a "prison-like" aesthetic, GCM's invisible grill system
uses high-tensile 0.8mm to 2mm SS 316 wire tensioned at precise intervals to create an
invisible barrier with 200kg+ load capacity per panel. Children and pets remain safe while your
balcony retains its full unobstructed view — a critical feature for high-rise apartments in Duvvada.
GCM is a direct manufacturer — meaning you buy at factory price with no distributor markup.
Our pricing in Duvvada starts from ₹120 per sq ft for 304 Grade and ₹160–200 per sq ft
for 316 Marine Grade. Free survey, no-pressure quote. Call 9912399224 today.
