Why should elevator doors have a smooth finish?

Having a smooth finish on elevator doors is essential primarily for preventing surface wear and enhancing the aesthetic appeal. A smooth finish minimizes the accumulation of dirt and grime, making maintenance easier and prolonging the door's lifespan. Additionally, this type of finish gives the door a polished and professional appearance, which is important in settings where visual impression is significant, such as in commercial buildings or modern residences.

A rough or poorly finished surface could lead to more significant wear and tear over time, detracting from the door's functionality and visual appeal. The choice of a smooth finish is a deliberate design consideration to ensure longevity while also meeting the expectations of users regarding appearance and maintenance.
