Mezzanine Floor Design
|Mezzanine Floor Design
Ideally buildings with eaves heights at around 6m or more provide the ideal opportunity to double your floor area by installing a mezzanine floor.
Mezzanine Floor Design Assumptions
Our quotation calculator assumes Standard Design Loading of;
4.8 kN/m² (100lbs/sq.ft) UDL- Imposed Load
|Minimum Characteristic Imposed Loads|
Workroom (without storage)
Canteens (but not kitchens)
Proprietary lightweight partition
|Light storage||Uniformly distributed
|Medium storage||Uniformly distributed
Hand Pallett truck
|Heavy storage||Uniformly distributed
Powered pallet trucks
|Note: The application of the concentrated load shall be in accordance with cl. 5.1.3 of BS6399: Part 1The assumed area of the concentrated load shall be recorded in the Management Document
Careful consideration must be given to mezzanine staircase design. Please view the following section for full details: Mezzanine Staircases
Exposed Perimeter Protection
To every edge of mezzanine which is not going to abut the building perimeter walls – Edge protection is required. This is provided by an 1100mm high hand & knee guardrail (50mm dia. Galvanised tube rail) supported between RHS or CHS upright columns with welded footplates at 1100mm centres. We offer an option to provide a 150mm high 5mm thick steel kicker to front edge of handrail posts to preclude falling objects rolling over the exposed edge of mezzanine. All guard-railing is designed & compliant with Building Regulations Approved Document K.
Generally all mezzanines used for either Light Assembly or Office use (ie anything other than storage & where personnel are using) require the provision of Fire Protection to the entire underside of structure in the form of fire rated Suspended Ceiling, Column cladding to all upright columns & fascia/bulkhead to exposed perimeter edges. Our 600x1200mm ceiling grid & tiles are installed generally 75mm below underside of lowest steelwork. Tiles are white fissured pattern (non-clipped). Column cladding is assumed in our calculator as galvanised face. White PVC faced options available (suitable when offices below mezzanine). Fascia bulkhead similarly is allowed standard as galvanised but also available in white PVC facing.
