Safe access & egress to Plant Rooms & other services is always required. The bigger the equipment, the better the access should be.
Maintenance Stairs are smaller / more compact than the usual stairs we build:
- minimum 600mm wide
- landing minimum 600mm too
- landing 600mm must remain unobstructed by door swings
- 100mm toe board if no structure within 10mm of landing
- balustrade is called ‘guardrail’.
Most of the basic Rules about Stairs remain generally the same:
- minimum 2m head height about pitch line
- 18 riser max
- consistent riser heights
- non slip
- continuous handrail and centre rail
However, landing balustrade height can be 900mm. Do yourself a favour & ALWAYS require minimum 1m.
Please remember that these stairs will need maintenance too. So:
- select durable / UV resistant products – aluminium preferred
- prime site welding carefully
- 40mm OD rails are more gradable.
