Header joist

A joist that runs perpendicular to other joists and supports the ends of joists that are cut off, often used around openings like stairwells.

A header joist is a horizontal structural member that supports cut-off joists around openings such as stairwells or chimneys, providing stability and load distribution. It is crucial for optimizing structural performance, enhancing durability, and supporting construction efficiency. By providing a reliable and effective support solution, header joists support efficient construction, improve structural integrity, and contribute to successful project delivery by ensuring that floor structures are robust, aligned with design specifications, and capable of withstanding applied loads and environmental conditions.
