This Is Why Some Window Grills Have a Curve at the Bottom – It’s Not Just for Looks
When metal bars are curved:
They distribute weight and pressure more evenly
They resist bending and warping
They withstand force from multiple directions
A straight horizontal bar can sag over time — especially if it’s long or made of thinner metal.
But a curved bar?
It acts like a spring, absorbing stress and bouncing back.
Think of it like a bow — flexible, but strong under tension.
And when it comes to security, strength isn’t just about thickness.
It’s about design.
🛡️ Why Curved Grills Are Better for Security
Resists prying
The curve makes it harder for tools to get a grip
Harder to cut
Curved bars create awkward angles for bolt cutters
