What is typically characterized by steel joists spanning between beams or bearing walls with depths ranging from 8 to 72 inches?

The open-web steel joist system is characterized by its use of steel joists that are arranged to span between beams or bearing walls. These joists are designed to support loads while allowing for a lightweight construction method, which contributes to the overall efficiency of the structural system. The depth of these joists typically ranges from 8 to 72 inches, providing flexibility in design to accommodate different load requirements and spanning distances. The open-web design allows for easy passage of mechanical systems, such as HVAC, through the joists without extensive modifications, further enhancing its practical application in commercial and industrial buildings.

The choice of an open-web steel joist system is often favored for its ability to provide large, unobstructed spaces underneath, which is essential for modern architectural designs.
