Stairway Tower - Spiral
The Stairway Tower - Spiral is a purpose-built access solution for the scaffolding sector, offering a modular, quick-assembly system ideal for high-traffic construction environments. Engineered in compliance with BS-EN 12811 standards, it provides a safer and more efficient alternative to traditional ladder access, and HAKI-type staircases-significantly reducing trip hazards and improving on-site mobility for scaffolders and other trades.
Stairway Tower - Spiral is a high-performance modular staircase system engineered for scaffolded sites where traditional ladder access is no longer sufficient. Ideal for multi-storey access and phased site setups, it delivers a compliant, low-risk route between levels that enhances speed and mobility for scaffolders, site managers and specialist contractors.
Designed for rapid installation alongside scaffold structures, it integrates seamlessly with system scaffolding and can be customised to suit varying lift heights. Easily repositioned via crane, it enhances site logistics and keeps pace with the evolving demands of scaffold erection and dismantling.
Key Features & Benefits
- BS-EN 12811 compliant for temporary works and scaffold integration.
- Modular, spiral construction maximises vertical access efficiency in limited spaces.
- Quick to assemble and disassemble-ideal for dynamic scaffold environments.
- Provides handrail-supported access for safe two-way foot traffic on busy sites.
- Minimises scaffold congestion and improves movement speed compared to vertical ladders.
Product Information
The Spiral Stairway Tower is frequently deployed on commercial high-rises, façade access projects, and infrastructure jobs where site teams need stable, non-ladder access between scaffold decks. Its compact spiral layout reduces trip hazards and eliminates the bottlenecks caused by one-person ladders.
Constructed from galvanised components and designed for modular re-use, it offers long-term performance across multiple projects.

Popular Uses & Applications
Used extensively in scaffold-heavy commercial and infrastructure builds where height access must be both safe and fast. Also ideal for M&E trades working across levels or for phased install teams needing quick vertical circulation between floors.
Perfect for scaffold contractors prioritising safety, productivity, and compliance under CDM regulations. Can be repositioned or expanded as the scaffold structure evolves.
Alternative Products
If straight-line access is preferred, consider the Scaffold Access Stairway. For lower height access, the Scaffold Access Bridge offers efficient cross-site walkways.
