In architecture, a mezzanine floor is an intermediate floor located between the main floors of a building. It is not usually counted among the overall floors of the building's structure. The mezzanine can have a low ceiling and is projected out in the form of a balcony. The term is also used for the lowest balcony in a theatre, or for the first few rows of seats in that balcony.
In industrial applications, the term 'mezzanine floor' is usually used to refer to a floor system installed in buildings between two permanent stories. They are usually free standing and can usually be dismantled and relocated. Mezzanine floors are usually constructed from a combination of three materials; steel, fibreglass and aluminium. Examples can be usually found in retail and commercial units, such as shops to store tools or materials. The high roof of the shop is ideal and offices can be put either below or above it.
Industrial mezzanine floors are usually either roll-formed, rack-supported, structural or shelf-supported, allowing for high density storage within the mezzanine structure. Mezzanines are frequently used in warehouses, distribution centres and manufacturing plants.
Mezzanines are also frequently used in airports or any location where the structure ensures a better use of space and in turn, clients can save money and increase their profitability.
