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
