How to calculate how much weight a Mezzanine Floor can safely hold?

Our customers often ask us for advice on the weight loading of their mezzanine floor.  The weight loading is worked out on a kilonewton per square metre basis (kN/m2) and depends upon what the customer wants to use the mezzanine floor for. 

As a general rule of thumb, dependent upon the usage, the following weight loadings are recommended:

  • 3.5kN/m2 – Office
  • 4.8kN/m2 – Light Storage
  • 7.2kN/m2 – Medium Storage
  • 9.6kN/m2 – Heavy Storage

What does Kilonewton per square metre actually mean?

Let’s take light storage as an example:

The load bearing recommendation for Light Storage is 4.8kN/m2, this basically means that the floor can hold a fully dispersed load of 480kg per square metre. If the customer wanted to store a piece of equipment on their mezzanine floor that weighed 2500kg and was 2 metres square, they would need to increase their load bearing weight to 7.5Kn/m2.

Thinking about your future needs

At Cubex we normally advise customers looking to install a mezzanine floor for office purposes to go for a 4.8kN/m2 floor (light storage) as it provides them with greater flexibility on what to use the floor for in the future.  This is especially relevant in a growing business as the cost difference is only small, and it is far more complex and expensive to try and retrospectively strengthen a floor later down the line.

If you are unsure about the correct load bearing for your floor, please contact one of our experienced designers here at Cubex Contracts on 01933 460422 – we’re always happy to offer advice and guidance.
