Stair stringers are crucial components in building staircases as they provide the support and framework for the stairs. These inclined beams or supports run along the sides of the staircase, connecting the treads and risers. Stringers are responsible for bearing the weight of the people using the stairs, transferring the load to the foundation or structure below. Properly designed and installed stringers ensure the stability and safety of the staircase, preventing it from sagging or collapsing under the weight of users. Whether in residential or commercial buildings, stair stringers are indispensable for creating secure and functional staircases.
