What is a "stringer"?

A stringer is a long, horizontal support beam in a staircase that runs along the sides, holding the treads and risers in place. It provides structural stability and helps distribute weight, ensuring the staircase is strong and safe to use. Stringers can be made from various materials, including wood, metal, or concrete, and can be visible or hidden, depending on the staircase design.
