Exterior Zink Spiral Staircase

The Exterior Zink spiral is a kit system supplied for external use.  It is an adjustable stair supplied in three diameters.  It has pressed steel treads with a non slip perforated detail for water drainage and it arrives as standard fully galvanised for protection from the elements.

The kit is delivered with 13 risers which includes a top platform plate which sits level with the upper level.  The 13 riser kit will span floor heights upto 2990mm.  Should your height be higher than this then you can simply add treads and risers to the flight.

The finish is always galvanised but there is an option to have a white or black powder coated finish to make it appear less industrial.
