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

What Are Window Grills?

Window grills (or grilles) are the metal or wooden bars installed over windows. They provide:

• Security against break-ins
• Protection from accidental falls
• Aesthetic charm, adding character to windows

The Purpose of the Curved Bottom

1. Safety First: Preventing Injury

One of the primary reasons for the curve at the bottom of window grills is to reduce the risk of injury.

• Straight bars ending abruptly can be sharp or pose a hazard if someone accidentally bumps into them.
• The curve softens the edge, making it less likely to cause cuts or bruises.
• In households with children, this curved design helps prevent accidents.

2. Better Drainage

Curved bottoms also help divert rainwater away from the window sill and frame.

• Water tends to run off the curved surface rather than pooling at the base.
• This reduces the chances of rust, water damage, and mold buildup, prolonging the grill’s life.

3. Enhanced Strength and Flexibility

The curved shape provides structural benefits:

• Curves naturally absorb and distribute stress better than straight lines.
• This means the grill is less prone to bending or breaking under pressure.
• It adds resilience against impacts, making your home safer and more secure.
