Technical specifications
| Specification | Value |
|---|---|
| Working load | 250 to 500 kg/m² in typical use, up to 1,000 kg/m² on study |
| Required ceiling height | at least 4.5 m to clear about 2.1 m below and above the mezzanine |
| Ground bearing | permissible slab load to check under the columns: up to several tonnes per column |
| Access and safety | stairs, guardrails, pallet safety gates, hatches |
| Upper-floor uses | storage, workshop or offices |
| Variant | rack-supported storage platform, over 2 or 3 tiers |
How to calculate a mezzanine floor load?
The working load is calculated from the actual use of the floor:
- Archives and light boxes: 250 kg/m² is usually enough
- Storage on picking shelving: 350 to 500 kg/m² depending on density
- Pallets or machinery: 500 to 1,000 kg/m², with a specific study of bearing points
- Always check the permissible load of the building slab under the columns: up to several tonnes per column
- Plan the accesses: stairs, pallet safety gates for loading, conveyor openings
Free-standing mezzanine or rack-supported platform?
| Criterion | Free-standing mezzanine | Rack-supported platform |
|---|---|---|
| Load-bearing structure | Free-standing floor on columns | The racking itself carries the floor |
| Upper-floor use | Storage, offices or workshop | Densified picking and reserve |
| Levels | 1 to 2 extra levels | 2 or 3 tiers |
