- Two-way access traffic - Handrail-supported stairs reduce ladder congestion on busy scaffold towers.
- Quick to install - Crane-compatible design allows fast scaffold stairway deployment and repositioning.
SKU WO89991z-1
This scaffold stairway system provides safe and efficient vertical access for high-rise or multi-deck sites. The spiral stairway tower design maximises space while maintaining steady two-way foot traffic. Quick to assemble and BS-EN 12811 compliant, it’s ideal for scaffold teams working on complex builds where secure height access and flow management are essential.
Spiral Scaffold Stairway Tower is a modular height-access solution built for projects where ladders fall short. It replaces temporary ladders with a stable, compliant scaffold stairway—giving scaffolders, contractors and M&E teams safe and continuous vertical movement between levels.
Compact and spiral in form, it fits within tight scaffolding layouts and congested worksites. Ideal for phased or high-rise builds, this stairway tower streamlines foot traffic, improves safety, and reduces fatigue during shift operations.
Key Features & Benefits
- Spiral configuration - Saves space on site while providing continuous upward/downward movement.
- BS-EN 12811 compliant - Fully certified scaffold stairway meeting UK access safety standards.
- Two-person access width - Supports bi-directional foot traffic between scaffold lifts or working decks.
- Modular segments - Height scalable from 2.5m to 18.5m, depending on project scope.
- Galvanised steel frame - Durable finish protects against corrosion, ideal for long-term jobs.
The spiral scaffold stairway is critical for safe vertical access in commercial refits, infrastructure works or scaffold-intensive façade projects. By reducing reliance on ladders, it supports higher site compliance and speeds up trades' movement between levels. Suitable for internal fit-outs or external scaffold rigs where elevation is significant and ongoing access is required.
Easily repositioned by crane, the modular stairway tower can adapt to different scaffold phases. Use in conjunction with Scaffold Access Bridge for lateral foot traffic or the Straight-Line Scaffold Stairway where spiral access isn’t needed.
HERMEQ stocks a wide range of equipment for Working at Height including Edge Protection Systems, Fall Arrest Systems, and Harnesses & Lanyards conforming to all required safety specifications and regulations.

What is the maximum height the scaffold stairway can reach?
The stairway tower can reach up to 18.5 metres depending on the number of installed modules.
How many users can access the stairway at once?
It’s designed for two people per flight simultaneously, ensuring safe bi-directional use on-site.
What material is it made from?
Each stairway module is constructed from galvanised steel to withstand harsh weather and long-term use.
How long does it take to install?
Assembly can typically be completed in just a few hours depending on height and layout.
Can it be customised for different sites?
Yes, the modular design supports height customisation and fits standard scaffold frameworks.
