Buyer's guide
Static vs mobile shelving — what's the difference?
Mobile shelving (also called roller racking, compactus or high-density storage) mounts shelving bays on wheeled carriages that glide along floor-fixed rails. Instead of a permanent aisle for every bay, the entire run compacts together — and a single shared aisle is opened only where you need access.
The result: up to twice the storage capacity in the same footprint, or the same capacity in half the floor space. It's used in archives, NHS records, libraries, museums, evidence stores, legal firms, councils, universities and commercial offices across the UK.
Mobile vs static — at a glance
- Floor-space efficiency: Mobile uses one shared aisle; static needs an aisle for every bay.
- Storage density: Mobile typically doubles capacity in the same room.
- Future-proofing: Mobile grows with you — add bays without expanding the building.
- Security & GDPR: Bays close together and lock as one solid block.
- Cost over time: Lower property cost per item stored — payback often 2–4 years.
