Description
A Window Invisible Grill is a modern safety solution installed on windows using high-tensile stainless-steel cables that appear almost invisible from a distance. These cables are fixed vertically or horizontally between aluminium frames, creating a strong protective barrier while maintaining clear outside visibility and airflow.
Invisible grills are commonly used in apartments, high-rise buildings, and modern homes to improve safety without blocking natural light or the exterior view.
What is a Window Invisible Grill?
A window invisible grill consists of thin stainless-steel wires tensioned between top and bottom frames. The wires are very slim (usually 2–3 mm thick) and spaced evenly, making them almost invisible from afar while still providing strong protection.
The system is designed to:
-
Prevent children or pets from falling out of windows
-
Protect against birds or pigeons entering the room
-
Maintain ventilation and natural light
This makes invisible grills an ideal replacement for traditional iron window grills.
Main Components
1. Stainless Steel Cable
-
Made from SS304 or SS316 stainless steel
-
Diameter typically 1.5 mm – 3 mm
-
High tensile strength for safety
2. Protective Coating
-
Nylon or PVC coating on steel cables
-
Prevents corrosion and rust
-
Improves durability
3. Aluminium Frame
-
Installed at the top and bottom of the window
-
Holds the cables under tension
4. Tension Lock System
-
Maintains cable tightness
-
Ensures structural stability
