Types of Industrial Mezzanine Floors And Raised Storage Areas

Our mezzanines floors can be constructed from conventional rack frames either with or without Sigma beams. Sigma beams are usually used to provide wider spans between columns, and are ideal for larger installations. Mezzanine offices constructed with standard box beams for narrower spans are recommended for small to medium facilities as they are cost-effective and quicker to erect.

Sigma Profile Mezzanine Floors

If you require larger spaces with greater spans between columns, the patented Sigma Beam Mezzanine Floor answers your need. This option utilises the patented Sigma profile for both the primary and secondary beams, enabling large spans between columns. In this type of installation, long span shelving and carton live shelving can be integrated into the raised storage area.

Mezzanine Level FAQs

It can be difficult to decide on whether or not a mezzanine floor is right for your property. Feel free to speak to us for advice or take a look at our frequently asked questions.

What is a mezzanine?

A mezzanine is a structure that sits above the main floor of a building but isn’t a completely separate and isolated storey. Instead, the mezzanine is open on at least one side and looks over the floor below. Mezzanine floors can also be built completely separate from the base building without using any of the base building as support. Instead, a mezzanine is supported with its own dedicated support columns.

How much does it cost to build a mezzanine?

Mezzanine floors vary by size, design, material, and how much weight they can support. Because of this, the cost to build a mezzanine level changes depending on the situation. A smaller mezzanine with a more standard design is going to be a lot less expensive than a large mezzanine with custom design features. Speak to us about what you need out of your new mezzanine and we can supply a quote.

Does it take a long time to build a mezzanine floor?

This also depends on the size, design, and other factors in building the mezzanine. Many mezzanine designs use modular components that can be pre-fabricated offsite. This means that the actual building of the mezzanine can be done quickly and easily once onsite. This limits disruption and downtime for the business getting the new mezzanine level installed. Once the size and design of the mezzanine is confirmed we can provide an estimate of how long the new mezzanine level will take to manufacture and install.

How much weight can a mezzanine floor support?

Mezzanines can be rated to support almost as much weight that the ground can support. How much weight a mezzanine can support is dependent on the overall design of the mezzanine though. There are a number of solutions that allow the mezzanine to either support more weight or be supported by pallet racking or shelving, allowing access to racking and shelving from the mezzanine without the mezzanine actually needing to support the weight.

Is it easy to remove a mezzanine floor?

Since a mezzanine level isn’t attached to the base building, it’s relatively easy to dismantle and move to another area of the building or even move to a new building if the business is moving. Although mezzanines are built to last, ultimately they can be treated as a temporary structure or semi permanent structure that can be removed when a commercial lease is done.

Does building a mezzanine level require planning permits?

Planning permits are usually required to build a new mezzanine level, but this will depend on the exact size and design of the mezzanine as well as planning requirements for the local area the mezzanine is being built in. If you’re unsure whether you need a permits to construct the mezzanine, we can help with this.

Is adding a mezzanine level the same as adding another storey?

What is defined as an additional storey and what’s defined as a mezzanine depends on the design and the size of the mezzanine; at some point, even if a mezzanine is supporting itself, a mezzanine covers so much of the floor below that it needs to be considered a new storey to the building. It’s best to speak to an expert regarding the desired size of the mezzanine and the permits required.
