A mezzanine is an intermediate floor in a building. Mezzanine structures are built to efficiently use the available space in factories and warehouses where there is sufficient height for additional floors. They are estimated to be a sturdy and cost-effective solution to build extra floors and create additional space within industrial buildings.

Shelving mezzanine uses existing shelving to support a second floor or mezzanine. This system is commonly used to increase space in a warehouse. The second floor can be used as external storage space for a warehouse or as an office.
