What is the main purpose of a balustrade?

The main purpose of a balustrade is to provide safety by preventing falls from elevated structures such as staircases, balconies, or decks. While the option chosen highlights a concern that may arise with users slipping, the balustrade primarily serves as a protective barrier along the open sides of stairways or elevated areas. This physical barrier helps to keep individuals safely within the area and prevents them from inadvertently falling off the edge.

A balustrade typically comprises a series of balusters (vertical posts) topped by a handrail, working together to ensure both safety and stability. The design of a balustrade can also influence the overall aesthetic of a space, contributing to the decor and style of the stairs or area it surrounds.

In contrast, supporting stair treads and securing stair structures are functional components of the overall stairway that do not specifically pertain to the role of a balustrade. While a balustrade may enhance appearance, that is not its primary function. Its critical role is in ensuring safety and providing a firm edge that individuals can hold onto while navigating stairs or elevated areas.
