The main reason for using a mezzanine floor is for extra storage. This usually means using a combination of long and short span shelving above and below the floor. A lot of businesses will use one of the levels for storage and the other for an office.
Mezzanines that are meant for offices can be built in either a factory or warehouse environment and by using the correct materials, a great work-space can be created. All facilities like toilets and canteens can be included in these self-contained offices.
Retail companies often use mezzanines to increase their selling space and storage at the back of the shop. When retail businesses use mezzanine floors, there are very strict rules that need to be followed like; the stairs and handrail have to be suitable for the public and the floor needs to have been fire rated.
