This Is Why Some Window Grills Have a Curve at the Bottom – It’s Not Just for Looks

Long bars stay rigid without needing thicker metal

In high-crime areas or ground-floor apartments, this subtle curve can be the difference between a secure window and a vulnerable one.

🌧️ Bonus: Helps With Water Drainage

Here’s another clever reason:

The curve helps shed rainwater.

A straight horizontal bar can trap water, leading to:

Puddles on the sill

Rust and corrosion over time

Mold or mildew buildup

But a curved bar?

It encourages water to run off the ends — keeping the window drier and the metal in better condition.

It’s a small detail that extends the life of the grill — and protects the window frame.

🎨 A Touch of Beauty, Too

Let’s not ignore the visual appeal.

The curve adds grace to what could otherwise be a harsh, industrial look.
