Mezzanines

An industrial mezzanine is a free-standing floor on columns that creates an extra level for storage, a workshop or offices. The catalogue documents columns, beams and joists, metal, timber or grating floors and access accessories. It publishes no universal design load or minimum height; structure, access and loads are engineered for the project.

  • Extra usable area at height
  • High load capacity
  • Integrated stairs and railings

Frequently asked questions

What is an industrial mezzanine?

An industrial mezzanine is a free-standing steel floor creating an extra level in a warehouse or premises: storage, workshop or offices. It uses available height; feasibility, loads and access are checked through a project study.

How much floor space can an industrial mezzanine add?

It adds usable area above the existing floor, but no automatic doubling or standard area can be promised without a layout. The result depends on clear height, walkways, access, columns and the slab’s permissible load.

What working load can a mezzanine floor carry?

The catalogue reviewed publishes no design load per square metre. It must be calculated from goods, racking, machinery, people, concentrated loads, structure, supports and slab capacity.

What clear height is needed for a mezzanine?

No universal minimum height is published. Clear height, services, access, clearances and applicable requirements must be surveyed and checked in the building study.

Which access and fall-protection equipment should be planned?

Depending on the flows, the project may include stairs, guardrails, kick plates, a pallet safety gate and hatches. References, layouts and applicable requirements are set out in the study; no general certification is published for this page.

How are the slab and anchors checked?

The load at each column, slab capacity, anchors and any floor services must be checked before installation. Kollirama includes them in the survey and sizing file; no slab capacity should be assumed.

Which regulations apply to an industrial mezzanine?

The project must be checked against its use and building: worker safety, escape routes, fire safety, access, loads and any public-building or planning rules. This page does not claim automatic compliance or certification without project-specific evidence.

What maintenance is needed after installation?

Plan visual checks of columns, connections, floor, stairs, guardrails, kick plates and gates, especially after an impact or load change. Frequency, procedures and any statutory inspections must be defined in the installation file and instructions.
