Scaffolding Towers: Durable and Safe Solutions for Construction Needs
Scaffolding staircases provide secure, code-compliant vertical access on construction sites, blending the stability of fixed stairs with the flexibility of modular scaffolding. Avanza Steel’s MS stair units feature precision-fabricated mild steel frames, non-slip treads, and adjustable connections, making them ideal for multi-level access in residential, commercial, and industrial projects.
What Is a Scaffolding Staircase?
A scaffolding staircase is a prefabricated stair unit that integrates into a scaffolding structure, offering a safe ascent and descent between deck levels. Unlike ladders, these stairs have constant rise/run dimensions, full-height handrails, and toeboards, ensuring compliance with BS EN 12811–2 and OSHA 1926.1053 standards.
Top Advantages:
-
Enhanced Safety: Continuous handrails at 1 m height, rigid guard-toeboards, and non-slip treads reduce fall risk.
-
Modular Flexibility: Units in 1 m, 1.5 m, and 2 m rise configurations stack seamlessly on standard scaffolding frames.
-
Rapid Installation: Tool-free couplers and captive nuts enable one-person assembly in under 5 minutes per flight.
Durable Finish: Hot-dip galvanization (85 µm) protects against corrosion in outdoor environments.

Applications & Use Cases
-
Multi-Story Residential Projects
Provide safe house-to-house vertical access during blockwork and plastering operations.
-
Commercial Fit-Outs
Facilitate rapid, code-compliant access across mezzanine floors, atriums, and service risers.
-
Industrial Maintenance
Enable inspection and servicing of equipment at height in factories, warehouses, and power plants.
-
Event & Temporary Structures
Deploy stair units in grandstand scaffolds and exhibition platforms for crowd access under safety regulations.
Installation & Best Practices
-
Site Preparation
-
Ensure supporting scaffolding frames are plumb and level; install MS base plates or soleboards on uneven ground.
-
-
Stair Unit Placement
-
Position the stair unit against the landing ledger; align the captive nuts with pre-drilled holes.
-
-
Securing Connections
-
Insert M12 bolts through the stair bracket into the ledger; hand-tighten and then torque to 25 Nm to prevent loosening under load.
-
Clip-on toeboards at each landing platform to contain debris.
-
-
Handrail Assembly
-
Slide the handrail tubes into the fixed sockets on the side frames; secure with spring-pins.
-
-
Landing Integration
-
Ensure adjacent deck planks or walkways butt flush against stair stringers; use transitional plates or MS jaali walkway units for seamless entry and exit.
-
Maintenance & Lifecycle
-
Before Each Use: Confirm stair treads are free from debris, inspect bolts for full engagement, and test handrail stability by applying lateral pressure.
-
Monthly Thorough Inspection: Examine welds for cracks, check galvanization integrity, and lubricate coupler threads with light machine oil to prevent galling.
-
Post-Use Care: Wipe down surfaces to remove cement splatter; stack stair units upright in a covered area to avoid moisture accumulation.
-
Lifecycle Management: Replace any stair unit showing > 5 mm tread deformation, bent stringers, or compromised handrail sockets to maintain safety compliance.
