Warehouse racking

Structures & Platforms

Free-standing structures include column-supported industrial mezzanines, rack-supported platforms, access walkways and industrial canopies. They create storage, picking, workshop, office or sheltered outdoor space around the existing building. Loads, bearing points, access, fire strategy and planning requirements must be calculated and approved for each project.

  • Mezzanine storage platforms
  • Storage walkways
  • Industrial carports

Technical specifications

Specification Value
Solutions Free-standing mezzanine, rack-supported platform, access walkway and industrial canopy
Uses Storage, multi-tier picking, circulation, workshop, offices or outdoor shelter subject to design
Imposed load Calculate from distributed and point loads, the storage layout and actual operation
Structure and bearings Column grid, spans, bracing, anchors and slab capacity must be checked
Floor and roof Build-up, fire performance, finish, weatherproofing and rainwater drainage to confirm by solution
Access and safety Stairs, guardrails, kick plates, gates or pallet transfer gates according to flow and risk assessment
Compliance Planning, fire safety, accessibility and workplace requirements to check with the competent parties
Installation and care Installation conditions, periodic inspections and maintenance plan to define in the technical file

Solution families and project photographs come from Kollirama content and archives. No standard load, span, floor build-up, certification or blanket planning exemption is published for the full range: these details must be confirmed in the structural calculation and project file.

Available products

Industrial mezzanine Independent floor on columns for storage, workshop or office use. Load, clear height, column grid, slab, stairs and edge protection are engineered for the project.
Rack-supported storage platform A platform in which the racking contributes to the load-bearing structure for multi-tier picking and reserve stock. Racking compatibility and all loads must be approved.
Walkways Elevated routes linking platforms or multi-tier picking areas. Width, access, guardrails, kick plates and escape provisions are defined for the use and applicable rules.
Industrial canopies and carports Shelters for vehicles or outdoor storage. Structure, finish, roof, wind, snow, rainwater drainage and permissions must be confirmed for the site.

How is an industrial mezzanine or storage platform sized?

The design office must start from the site and intended operation rather than applying a generic floor load:

Frequently asked questions

What is the difference between a free-standing mezzanine and a rack-supported platform?

A free-standing mezzanine has its own column grid and can be designed for storage, workshop or office use. A rack-supported platform uses the shelving as part of the load-bearing structure and mainly serves multi-tier picking and reserve stock. Loads, flows and the building determine the right solution.

How is the load capacity of a storage platform determined?

Capacity cannot be selected from the product type alone. The study records distributed and point loads from goods, shelving, machinery, people and handling equipment, then checks the structure, bearings, anchors and slab. The approved capacity must be stated in the final technical file.

What information is needed for an industrial mezzanine study?

Provide building plans and dimensions, clear height, obstructions and services, intended use, products and maximum weights, shelving or machinery, flows, access and the load-transfer method. A site survey can complete this information.

Is planning permission required for a mezzanine or industrial canopy?

Requirements depend on location, area, use, whether the structure is indoors or outdoors and local rules. A demountable structure must not be assumed to be exempt. Planning, fire safety, accessibility and workplace requirements should be checked by the competent parties before work.

Which access and edge-protection equipment is needed?

The project may require stairs, guardrails, kick plates, gates, pallet transfer gates or openings. Their number, size and location depend on flows, handled loads, escape routes and the risk assessment and must be approved on the drawings.

How is a free-standing structure installed?

Once the survey, calculations and drawings are approved, installation is planned around site access, unloading, exclusion zones, anchors and building interfaces. Phasing, lifting equipment, the estimated schedule and handover checks are specified for the project.

What maintenance is required after installation?

The technical file should define inspections and maintenance for the structure, floor or roof, anchors, stairs, guardrails and transfer equipment. Any impact, corrosion, deformation, change of use or suspected overload should trigger a check before continued operation.

How much does an industrial mezzanine or canopy cost?

Cost depends on area, loads, spans, slab, floor or roof build-up, access, protection, regulatory constraints, transport and installation. Plans, intended use and expected loads are needed for a project study and quotation rather than a generic price that may not apply.
