Heavy-duty steel telescopic tunnel structures — built to extend your workspace, protect your operations, and secure your assets. Fully bespoke, designed and fabricated in Keighley.
Our retractable tunnels are fabricated from heavy-gauge box profile steel sheet in a precision telescopic system — not tarpaulin, not PVC, not tent fabric. Every retractable telescopic tunnel structure is engineered for longevity, structural integrity under load, and practical day-to-day operation.
Designed and built by our fabrication team in West Yorkshire, each tunnel is made to order against your exact dimensions and site conditions. Whether you need a mobile unit that can be relocated as your business grows or a fixed installation on floor-mounted or sunken tracking, we'll engineer the right solution.
With over two decades of steel fabrication experience across industrial, sporting, and commercial sectors — including major clients in brewing, aerospace, and UK sports venues — Waterside Fabrications brings genuine engineering capability to every project.

Box profile steel sheet sections slide and nest for smooth, reliable operation — our retractable storage enclosures are engineered for repeated daily use over many years.
No standard sizes. Width, height, and extended length are all specified to your requirements. Internal and external installations both accommodated.
Available as freestanding mobile retractable tunnel structures or fixed installations. Dismantlable and re-erectable if your operations move or expand.
Retractable tunnel track system specified to suit your floor type, load requirements, and operational preferences — flush-to-floor options available.
Hot-dip galvanised, powder coated, or wet-painted to specification — our retractable tunnels are available in any RAL colour, including your corporate or site livery.
We handle everything from design and fabrication through to professional on-site installation of your retractable tunnel and commissioning by our own team.
Solid steel infill doors provide a complete weathertight and secure enclosure. Ideal for high-value goods storage, sensitive manufacturing environments, or locations requiring maximum protection from the elements.
Heavy-duty welded steel mesh doors combine robust access control with essential ventilation — the preferred choice for spray booths, aggregate storage, and loading bays where airflow matters as much as security.

All our retractable tunnels are designed and built by our own team at Progress Works in Keighley — no subcontracting, no compromises. You get a direct line to the engineers building your structure.

Our work spans aerospace, nuclear, Premier League stadia, international brewing, and heavy industry. We understand exacting specifications and tight programmes.

Steel telescopic tunnel construction outlasts PVC and fabric retractable tunnels by decades. Built and finished to a specification that protects your investment for the long term.
