Access & Safety / Scaffolding
Haki Stair Tower System
A certified modular temporary access stair tower engineered for rapid, high-safety multi-level access on construction, infrastructure, public event, and industrial sites. Manufactured with captive pocket connections, integrated stair flights, robust guardrails, and self-closing safety gates conforming to BS EN 12810 / 12811.
Key Highlights
- Pre-fabricated stair flights in 2.0 m (42.1 kg), 1.5 m (35.3 kg), and 1.0 m (32.0 kg)
- Fully integrated perimeter guardrail frames in both ledger and transom directions
- Self-closing safety gates and clip-on handrail posts for zero fall risk
- High live load rating suited for two-way site traffic and emergency evacuation
- Manufactured to British & European Standards (BS EN 12810 / 12811)
- Hot Dip Galvanized finish for maximum rust prevention and decades of service
The Industry Standard in Temporary Access & Egress
Malmo's Haki Stair Tower System sets the benchmark for safe vertical movement of personnel and light materials on multi-story construction and civil engineering projects. Unlike cumbersome ladders, Haki provides wide, non-slip stair treads and comfortable rise angles that significantly reduce worker fatigue and site transit times.
Built with heavy-gauge 48.3 mm high-yield steel tube standards and drop-in stair flights, the tower can be configured as a standalone 4-leg access tower, integrated directly into existing scaffold facades, or set up as a public access footbridge stair conforming to local building and safety regulations.
Why Engineers Specify Malmo Haki Towers
- Safe Two-Way Traffic — Generous staircase width allows workers to pass comfortably without pausing or bottlenecking.
- Rapid Modular Assembly — Captive hook-in ledger beams and stair flights lock swiftly into standard pockets.
- Complete Edge Protection — Pre-formed guardrail frames protect both ledger and transom directions at every landing.
- All-Weather Galvanized Finish — Deep hot-dip galvanizing protects all components from offshore, marine, and abrasive industrial environments.
