The Exterior Zink Spiral Staircase is the perfect cost effective solution for an external staircase. The treads are formed with perforated steel plate with balustrade constructed with vertical steel spindles and a nylon handrail. It is a kit system, meaning the risers and rotation are adjustable at the moment of assembly, making it extremely versatile. There are three diameters to choose from and the steelwork is always supplied fully galvanised. The stair can be purchased galvanised or you could opt for a black or white powder coated finish on top of the galvanised finish to blend in better with your surroundings.

Riser bars are can be added to the order to reduce the gap between the steps.
In the UK the regulations specify a maximum gap between the treads of 100mm. This is to prevent small children falling through the gap.
These riser bars are formed with a 20mm steel bar which is fitted horizontally between the steps which keeps the riser open whilst reducing the gap.
The riser bars can be added to the order above by simply selecting YES on the riser bar drop down.
If you are unsure if you require them, please check with your building control officer.
These can be fitted retrospectively once the stair is assembled but should they are ordered separately, a further delivery charge would be due.
