Design and Installation
A mezzanine floor is a raised platform, typically independent of a building structure and supported by columns, racking structures or other adequate foundations. They don't always require planning permission, but they always need to have approved building regulations - this is most important!
Before building a mezzanine floor or deciding which one to get installed you must always consider fire protection, emergency lighting, smoke and fire alarms, along with relevant safety signage for all appropriate areas and passageways - particularly where there is a high volume of staff occupying the area on a permanent basis.
Fire protection can include (but is not limited to)...
- Suspended ceilings
- Column casings
- Smoke detection systems
- Bulkheads / fascias
- Sprinkler systems
- Exit staircases and more...
All of these features can be incorporated at the planning stage and are an essential way of fulfilling the standard health and safety requirements relating to the building and installation of mid to large size mezzanine floors.
Along with fire safety features and building regulations, the BRE Digest 437 must also be taken into account. BRE Digest 437 strongly suggests that guards and handrails should be incorporated as part of a mezzanine floor from the get-go, not as an additional attachment! It also states that traditional chipboard decking is not as sufficient for long-term structural safety and that P5 or P7 particle board is recommended as an alternative to maximise long-term structural safety, along with appropriate edge protection to stop employees falling.
SEC Storage is a mezzanine floor supplier fully compliant with all requirements of BRE Digest 437 specified building regulations, and all elements can be incorporated at the planning stage.

What Can They Do For You?
Mezzanines can improve operational efficiency without necessarily increasing the prospect of higher rent costs. There is also less pressure to expand your overall footprint due to the floor being built on currently occupied space, which means additional savings can be potentially spent on other areas including staffing and resource. A win-win scenario!
An example to the right: Our warehouse mezzanine floor design project for Karndean Designflooring allowed for the relocation of a primary business function, and in the process, increased floor space to provide an additional 1,140 pallet positions, boosting total warehouse capacity to nearly 11,000 pallets overall. A major increase, and a solution that effectively utilises all aspects of the available warehouse space.
The ability to insert mezzanine floor structures into spaces has also been positively encouraged by the UK Government for actively promoting the maximum footprint of a current warehouse space. Mezzanine floor construction is often seen as a more sustainable solution to the current expansive needs of the warehousing industry, so not only do you get a cost-effective, space-saving solution, you get the kudos for installing a sustainable one as well.

The Benefits of Mezzanine Floors
Mezzanine floors are highly useful for any purpose that requires additional space. This could include a number of needs, for example:
- Production areas / assembly lines
- Picking and packing / bulk storage areas
- Dedicated machine operations
- The creation of new office spaces / boardroom areas
- Security areas for high-value products and more...
- A mezzanine construction project can add multiple floors to structures less than 200 sq/m without the need for additional planning permission. This then converts your mezzanine floor into a multi-tiered structure. For more information on this, consult our Guide to...Multi-Tier Racking Systems to find out more
- The added space provided by the installation of a mezzanine floor can help to optimise picking operations when combined with the right accessories to compliment - such as goods lifts and gravity chutes
- Mezzanine floor structures can be built upon long-span shelving and rack supported structures, meaning the foundational support of the structure can act as a storage unit in itself
- They are considered to be a highly cost-effective solution when compared to the price of warehouse expansion
Back to the top!
- The Government has brought in additional legislation regarding mezzanine floors that are greater than 200 sq/m. These now require planning permission (which is something our team can assist with)
- Depending on the size of the mezzanine, especially those that are rather large, lead times for assembly and construction can take multiple weeks (this is, of course, an expectation across the industry and can be dealt with effectively at the planning stage)
- Small mezzanine floors, built for storage purposes only do not always need to be fire rated, as long as the dimensions do not exceed 20m in length or width, and the floor does not exceed more than 50% of the floor area of the space that it is installed in. Anything that exceeds these recommendations will have to be fire rated, with a minimum fire rating of 60 minutes. Although this is not a specific drawback it can represent further costs, and it is something that needs to be taken into account at the planning stage

Mezzanine Floor Accessories
Components and accessories that can be incorporated into a mezzanine floor include (but are not limited to):
- Protective guards and handrails, as mentioned above in the BRE Digest 437 these are strongly recommended, along with edge of structure foot protection to maximise employee safety
- Mezzanine floor structures can be equipped with the recommended P5 to P7 particle boards for structural stability, or even provided with a galvanised steel mesh solution
- To maximise picking operations, goods lifts, gravity chutes and conveyor systems are the general go-to solutions, allowing you to optimise the distribution of product from the first to ground floor levels of the mezzanine
- Gravity chutes can help to maximise product transfer between floors
The above recommendations act as a small showcase for the possible accessories and components that can be incorporated into a mezzanine floor structure. Various configurations are available that can help to optimise both your picking operations and general warehouse safety and SEC can happily advise in greater detail at the planning stage should you chose to explore this option.

What is a mezzanine floor?
A mezzanine floor is an intermediate floor that does not extend over the entirety of a building's floor space. Mezzanines can serve a wide variety of functions, e.g. for use in industrial environments, to expand upon existing floor space and more. They may be temporary in nature or semi-permanent structures, depending on the users' requirements.
Can I put shelving on my mezzanine floor?
Yes, you can. A mezzanine floor can support numerous storage systems, including a variety of shelving systems. If you intend to put shelving, machinery or even offices on your mezzanine floor, it is important that it is designed with this use in mind at the beginning. One limitation will be the height of your warehouse.
Do I need to have my mezzanine floor inspected?
It is advised that you have mezzanines and storage systems inspected on a yearly basis by a SEMA Approved Rack Inspector, along with the addition of regular visual inspections through the course of the year. The inspection would include a check on the fire rating integrity of the structure, general checks on structural elements such as columns and the interaction of the floor structure with the warehouse floor.
How much does a mezzanine floor cost?
Mezzanine floor costs can vary considerably, depending on the size, specification and application. There are no standard mezzanines. A budget cost for a mezzanine floor used for basic storage purposes would be £100 per square metre.
How do I build a mezzanine?
Mezzanine floors are built using a number of components that are installed in order. These are columns, beams, joists, decking, staircase and handrails. Other build elements including pallet gates, column casings and suspended ceilings, or fire rating, would be installed last.
How to install a mezzanine floor?
A mezzanine floor should be installed by a reputable, certified company such as one that holds the Storage Equipment Installers Registration Scheme (SEIRS) qualification. The mezzanine floor should be installed in accordance with a drawing from the manufacturer and a detailed Method Statement for safety, using safety equipment and appropriate access equipment.
