Mezzanine floors are used to maximise the floor space when there is enough headroom. Often this is to create additional storage areas. The mezzanine floor can use either a timber joists or cold formed steel sections to support the floor. The main supporting structure usually consists of steel beams and columns on a regular grid. These can be supported on the existing floor if the loadings on the mezzanine are relatively low and the floor is well constructed. If this is not the case then new foundations will be needed. We need the following information to design a mezzanine floor structure:

an architectural layout of the building showing the area of the mezzanine floor and the preferred column positions

the imposed loading required for the floor (we recommend a minimum imposed loading of 250kg/m2)

details of the existing floor construction (if this is not available then we can still design the structure, but the details of the floor construction will need to be confirmed prior to fabrication, if the intention is to support the columns on the floor slab)

details of the ground conditions

details of any other equipment which will be supported by the floor

Design information

All design work is carried out in accordance with BS5950 (The structural use of steelwork)
