4. To Give a Better View and Safer Leaning Space
The curved design also creates a wider gap between people inside the building and the outside world. This enforced space means that those inside have ample room to lean out and get a better view of the street below, while those attempting to reach inside from outside are pushed farther back — making unauthorized access significantly more difficult. It's a clever security detail that also improves daily comfort for the residents.
5. Water Drainage and Debris Prevention
From a maintenance standpoint, the curved design also helps with water drainage. The outward curve prevents standing water, leaves, and other debris from accumulating at the base of the grill, reducing the risk of rust and long-term wear. This keeps the bars looking good and functioning well for much longer than flat-bottomed designs might.
