What is a stringer on stairs?

A stringer on stairs refers to the structural support element that runs along the sides of a staircase. Stringers are typically made of wood, metal, or concrete and provide support for the treads and risers of the staircase.

In traditional staircase construction, there are usually two stringers – one on each side of the stairs, with the treads and risers attached to them. The stringers are responsible for carrying the weight of the treads, risers, and anyone walking on the stairs.

Stringers can be either open or closed. Open stringers have their structural elements exposed, while closed stringers are enclosed and often have a decorative facing. The type of stringer used will depend on the staircase design and aesthetic preferences.

In some cases, especially for longer or wider staircases, additional stringers or support may be necessary to ensure the structural integrity of the stairs. Proper installation and reinforcement of stringers are crucial to prevent sagging or instability in the staircase.

Overall, stringers play a critical role in the safety and stability of a staircase and should be carefully designed and constructed to ensure a durable and secure stairway.
