Mezzanines are structures that provide an intermediate story between the two main stories of a building. They are used to increase a building’s floor space. There are many different types of mezzanine products and mezzanine systems. Examples include floor mezzanines, warehouse mezzanines, industrial mezzanines, steel mezzanines, and racking mezzanines. A floor mezzanine is a system of raised platforms that are designed to provide more working floor space in a building or factory. These mezzanine systems consist of modular mezzanines that can be assembled without drilling or welding. They are used mainly in retail stores and factory offices. A warehouse mezzanine consists of platforms, stairways, gates and railings that are designed to maximize existing storage space. Industrial mezzanines are warehouse mezzanine systems are configured in modules by height and type of material. Steel mezzanines are made of solid or perforated steel, and may include anti-skid flooring or bar grating for durability.

Mezzanines can be designed for either stacking or storing, and can be integrated with systems of drawers or cabinets. Racking mezzanines, mezzanine racking or mezzanine storage systems are constructed of platforms and railings to accommodate the storage load or factory production flow. Custom mezzanines can be designed to take advantage of unused space, or to integrate office space into a manufacturing cell or system. A custom mezzanine may be used to accommodate and integrate in-plant offices with storage and shelving units, and conveyor and vertical lifts. Since the production flow of each facility may be different, a custom mezzanine requires specific measurements and on-site consultation. In some cases, organizations can purchase used mezzanines or mezzanine materials, such as flooring, planking, rails, and stairways.
