Frequently Asked Questions

What are invisible grills made of?
Invisible grills are made of high-tensile stainless steel (SS 304 / SS 316) wires or nylon cables, fixed vertically and horizontally in a grid using anchor bolts and turnbuckles. They are rust resistant and built to bear high loads without any visible bulk like traditional iron grills.
Are invisible grills safe for children and pets?
Yes. Invisible grills are designed to bear significant weight and pressure, making them a safe fall-prevention barrier for children, pets and elderly family members on balconies, windows and open ledges.
How is an invisible grill different from a traditional iron grill?
Unlike bulky iron grills that block the view and rust over time, invisible grills use thin high-strength steel wires that are barely visible from a distance, preserving your view and the aesthetics of your home while offering equal or better safety.
How long does invisible grill installation take?
A standard balcony or window invisible grill installation is usually completed within 2 to 4 hours by our trained technicians, depending on the size and number of openings.
Do invisible grills require maintenance?
Invisible grills need virtually zero maintenance. Since they are made of rust-resistant stainless steel or coated nylon wires, an occasional wipe down is all that's needed to keep them looking new for years.
