While window bars don’t hold up buildings, they still need to withstand pressure — whether from attempted tampering or environmental stress.
How the Curve Makes a Difference:
A straight horizontal bar can flex or sag under force, especially if the metal is thinner.
A downward curve (forming a shallow “U” or “V” shape) increases rigidity.
The bend strengthens the metal through tension, making it more resistant to bending or prying.
Think of it like a potato chip:
Flat, it snaps easily. Add a curve, and suddenly it becomes much harder to break.
✅ The result? A stronger security system — without adding bulk or expensive materials.
🌧️ Better Drainage, Less Rust
Outdoor window guards are constantly exposed to rain and moisture.
A flat horizontal bar can collect water in the center, which may lead to:
Rust and corrosion
Gradual weakening of the metal
Staining on walls or window sills
When the bar curves downward:
Water naturally runs off to the sides
