Heavy-duty mezzanine floors
A heavy-duty mezzanine is designed for high floor loads, such as palletised stock placed by forklift, machinery or dense materials. It uses heavier hot-rolled steel beams and columns, a closer column grid or larger base plates, and a robust deck, all checked against what your existing floor slab can carry.
How we approach heavy-duty mezzanine floors
Heavy loads change the design in three places: the deck, the frame and the foundations. Decks move from chipboard towards steel plate or composite options, primary beams become heavier universal beams, and column loads rise, which puts more weight on each base plate.
That is why the floor slab matters most on a heavy-duty job. We review the slab thickness and condition, and where needed arrange cores or plate load tests, then size base plates or design new pad foundations so the point loads are spread safely.
Heavy-duty mezzanines are often designed around a specific use, such as a machine, a production cell or a pallet store, so the load notice on the finished floor states exactly what it can take.
What the job includes
- Design for high uniformly distributed and point loads
- Hot-rolled universal beams and columns
- Steel plate, grating or heavy chipboard decks
- Slab checks, cores or plate load tests where needed
- Enlarged base plates or new pad foundations
- Load notices fixed on completion
Best for: Pallet stores, engineering works, metal stockholders, plant and machinery floors.

Questions people ask
How much weight can a mezzanine floor hold?
As much as it is designed for. Light storage floors are commonly designed around 3.5 kN/m², medium storage around 5 kN/m², and heavy-duty floors 7.5 kN/m² or more. The rating is stated on a load notice.
Will my floor slab take a heavy mezzanine?
It depends on its thickness, reinforcement and condition. We check it, arrange cores or load tests if needed, and design base plates or new foundations to suit.
Can a forklift drive on a mezzanine?
Only on a floor specifically designed for it, which is unusual and costly. Most heavy-duty mezzanines take pallets placed by forklift from below through a pallet gate, with pallet trucks used on the deck where designed for.
