Exterior steel spiral stairs extension
This fire escape staircase complied with building regulations for a Category E spiral staircase, it was designed as a public stair that could be used by large numbers of people at one time.
The steel spiral staircase was galvanised to EN ISO 1461 for durability and designed to take weather protection into account. Protection panels were fixed to the new and existing staircase balustrade and a large circular canopy was installed at the top. Yellow contrasting nosing tape was added to the treads for visibility and compliance.
