We are going to answer a number of your frequently asked questions to do with mezzanine floors.
What is the maximum loading for a mezzanine floor?
A mezzanine floors loading is worked out from the British Standard load tables which are referenced against what your floor is being used for. The loading for a floor is broken down into bands, light use 4.8Kn/m2 (480kg per square metre) medium use 7.32Kn/m2 (732Kg per square metre) or for heavy usage 9.6Kn/m2 (960Kg per square metre). Should you have any questions you should speak to your floor designer.
Does a mezzanine floor need to be approved by building regulations?
Your mezzanine flooring will need building regulations to approve it. The mezzanine floor designer you are using will normally take care of this for you but you may need to still submit some plans of the building showing things like fire escapes. Once the submission is made it typically takes about 48 hours for you to obtain approval.
Do mezzanine floor s need planning permission?
You may need it but only if your car park is shared with other buildings or it belongs to the council.
Does my mezzanine floor need a fire rating?
Should your proposed floor exceed one of the following then you will need to give it a 1 hour fire rating on the underside of the floor.
1. The size of the floor area is larger than 400m2.
2. The size of mezzanine floor exceeds 50% of the room it’s going to be installed within.
3. The number of people working on the floor is going to exceed 3 at any one time.
4.The floor is going to be used for things other than storage, automated storage and maintenance.
Please note that you may not need any fire rating if you propose to have a sprinkler system to be extended to the underside of the mezzanine floor, but this can also be extremely costly to do.
Any additional items I need to know?

Should inform my landlord?

What type of decking do I need?

If liquids would be permanently accumulating on the mezzanine floor then a steel chequer plate would be used. An external mezzanine floor would use a open galvanised steel mesh or a galvanised steel chequer plate to stop rusting or rotting in the weather.
What needs to be done before installation?
Try to get the area in which the area your mezzanine floor is going to be installed is clear and that lighting and power is accessible, after that ensure your stocks of tea, coffee and biscuits are high for your installation team!
