Structural Engineering Details, Fleet Compatibility & Field Performance
Choosing Between 58 kg Galvanized Steel & 17 kg Aluminium Z-Staircases
For multi-year metro shafts, dam excavations, and heavy civil bridge piers erected by tower crane, the 58.0 kg hot-dip galvanized SM-A281 steel Z-staircase offers rugged impact durability. Where scaffolders erect and relocate stair towers manually without crane time, the 17.0 kg SM-A471 extruded aluminium Z-staircase cuts lifting weight by 70%.
Alternating Z-Configuration & Parallel Twin-Flight Access Towers
Inside a 150×250 cm (or 150×300 cm) Ringlock bay, two 60 cm stair flights sit side by side in alternating Z-directions with intermediate steel-plank landings. For 1.0 m ground-level transitions, dedicated 60×150 cm starter flights (SM-A282 / SM-A472) complete the entry cleanly.
Complete Handrail System: Inner, Outer & Top Exit Guardrails
Paired with dedicated inner stairwell handrails (SM-A286 / SM-A476), outer flight guardrails (SM-A287 / SM-A477), and top-landing exit guardrails (SM-A288 / SM-A478), every stair tower passes strict international HSE egress audits.
