Meaning of Mezzanine Floor

A mezzanine floor lies between two main floors of a building.

A mezzanine floor, also called an entresol, is basically a raised steel or concrete platform that is supported by posts. It lies between the two main floors of a building and is usually low-ceilinged, extending in the form of a balcony. Mezzanine floors are a cost-effective way to better utilize space while improving productivity and saving money that would otherwise be spent in leasing or building new infrastructure.

Types

There are various types of mezzanine floors designed for different end-uses. The three most common types of mezzanines include freestanding, catwalk and full mat, which are used in residential, commercial and industrial applications.

Freestanding mezzanines have solid, sturdy foundations and do not require additional reinforcements. They are stable and are considered a viable way to maximize floor space at the mezzanine level.

Catwalk mezzanines are also called shelving-supported mezzanines. They are an ideal solution for businesses that require additional working space plus storage areas. Catwalk mezzanines are typically supported by existing storage uprights and may be reinforced with additional cubic columns if the framing members are considered inadequate.

Full-mat mezzanines are a hybrid between freestanding and catwalk mezzanines. They provide additional space at the floor level like catwalk mezzanines and are open like freestanding mezzanines.

Materials

Mezzanine floors are typically constructed from fiberglass, aluminum and steel.

Advantages

Mezzanine floors convert empty overhead spaces into productive storage and/or work areas. Most industrial mezzanines are easy to assemble and disassemble, allowing for transportation ease. Mezzanine floors are customizable and tailor-made to suit the load-capacity requirements of a particular space. Mezzanine floors that meet safety standards are designed to be strong, stable, durable and safe and can easily accommodate multiple users.

Disadvantages

Mezzanine floors are liable to deflect and collapse under extreme stress or overload. Large base plates can prove to be a hazard. Companies must take all necessary design and safety precautions before installing mezzanine floors. Installation adjacent to or above an area where people are working must be avoided, for it is a potential hazardous risk.

Uses

Mezzanine floors are typically installed to increase the working space within an area, usually to accommodate additional storage space within the shell. They function as work platforms, enabling employees to gain access to systems and equipment from an intermediate level. Mezzanines are also used as observation decks, vision towers and second-story offices.

Mezzanine floors are used in shops, storage areas, manufacturing and distribution units and warehouses for the storage of materials and tools. They are common in postal services, steel-support structures, airports and baggage handling systems.
