What is a "joist"?
A joist is a horizontal structural element that supports a floor or ceiling in a building. Joists run parallel to each other and are typically made of wood, steel, or engineered wood. They help distribute the weight of the floor or ceiling to the walls or beams, ensuring the stability and strength of the structure.
