Steel spiral staircase
This external spiral staircase served the dual purpose of being both fire escape stairs and access stairs. It was fabricated in mild steel galvanised to ISO EN1461 and compliant with British Standard BS5395 Part II (Code of Practice for the design of helical and spiral stairs 1984).
Galvanising is a cost-effective way of increasing durability and preventing corrosion on exterior spiral staircases.
The staircase balustrade handrail was flat bar with a black PVC capping and the landing balustrade consisted of toughened glass infill panels.
