Warehouse racking

Mezzanines

The industrial mezzanine is a free-standing steel floor on columns that creates an extra level in a warehouse or premises: storage, workshop or offices, without structural work. Typical working load runs from 250 to 500 kg/m², up to 1,000 kg/m² on study. Kollirama sizes the structure, supplies compliant stairs, guardrails and pallet safety gates, and installs throughout France.
