Mezzanine Floor Definition

A mezzanine floor is a mid-level built between the floors and ceilings of two main floors or buildings. It extends over a specific area, rather than extending across the entire floor space.

The mezzanine should allow sufficient clear height for pedestrian traffic above and below the deck. In industrial environments, mezzanine systems are typically used to store inventory or other materials. Yet, mezzanine floor systems have been used in a wide variety of environments, including commercial office spaces, warehouses, manufacturing facilities, auto dealerships, and even breweries.

Mezzanine floors can be designed to many different specifications, including different load ratings, layouts, decks, railing types, etc.

What is Mezzanine Flooring made of?

Mezzanine floors are typically manufactured from a combination of steel, concrete, wood, stainless steel or even fiberglass. The construction of a mezzanine floor can be determined by the type of mezzanine and its purpose. Steel and concrete are the most common types of mezzanine construction. Some applications may require corrosion resistant materials such as stainless steel.

The majority of industrial mezzanines consist of modular, prefabricated steel systems designed to be quickly and easily installed at the factory. Steel mezzanines have the capability to be designed to provide support for heavy loads.

Mezzanine floors are commonly made of steel, wood, composite materials or concrete. Steel grating is used to provide slip resistance and drainage for the food manufacturing and waste management industries. Composite resin decking systems are low-weight and long-lasting for storage mezzanines. Concrete decking is considered the most sustainable for heavier industrial applications.

Safety Gates: These additions offer controlled access points on a mezzanine, further enhancing safety by preventing accidental falls.
Stair Systems: Mezzanine staircases are vital for providing access and must adhere to the International Building Code (IBC) for safe evacuation routes. Different options include standard IBC-compliant stairs and alternating tread stairs, the latter being suitable for smaller mezzanines or areas with limited space.

Special Considerations

Alternating Tread Stairs: These can be used if your mezzanine is less than 250 square feet and accommodates no more than five people. They also serve as secondary egress in larger spaces.

Each component is tailored to suit specific mezzanine applications, with flexibility in materials like aluminum or different finishes ensuring that your structure not only complies with safety standards but also fits the desired aesthetic and functional needs.

OSHA Requirements for Mezzanine Fall Protection

Mezzanines are very versatile areas, but they also present a danger of falling easily.

It is for this reason that OSHA regulations are timely to make provisions for mezzanine safety. Let's take a look at some of them.

● Facility managers are responsible for inspecting and maintaining fall protection systems, including mezzanine guardrails, gates, safety nets, self-retracting lifelines, etc.

● The top edge of the guardrail safety system must be 42 (±) 3 inches above walk level. Guardrails must withstand a force of up to 200 pounds in any outward or downward direction to comply with OSHA standards.

● Fall protection must be installed. Toe boards with a minimum vertical height of 3.5 inches are typically used for this purpose.

● All openings/holes in the work/walking area must be surrounded by guardrails or covered with a solid fastening solution capable of withstanding forces twice as great as those predicted.

● OSHA-regulated training programs must be provided for your employees.

● Facility managers need to ensure adequate lighting, frequent cleaning, regular inspections, and non-slip floors.

Benefits of Mezzanine Flooring

In a warehouse or manufacturing facility, a mezzanine flooring system offers several advantages.

First, a mezzanine floor takes advantage of unused space above a facility's floor and uses it in any way the facility sees fit. Whenever a facility needs a quick and economical solution to its space needs, a mezzanine floor is the best solution because it effectively doubles the available space it covers.

Other than the ability to create additional space, mezzanine flooring can be installed into a facility quickly and with minimal disruption to the site. In contrast to stick-built, prefabricated mezzanine floors can be manufactured off-site, allowing the structure to be quickly erected on site.

Contrary to stick-built, prefabricated steel mezzanine floors ensure that there is no wasted material on the project site, making clean-up as easy as possible. All of this means that the facility will have minimal downtime and increase its usable area quickly and efficiently.
