This popular spiral stair kit is available in 6 different diameters; 3 ½’, 4’, 4 ½’, 5’, 5 ½’ and 6’. All standard kits are in stock and can be shipped out immediately.
Our base kit includes one platform and 10 steps (11 risers) but additional treads can be added to accommodate any height.
Flat Metal Tread – Our base kit has a flat metal tread.
Checkerplate Tread – We recommend the checkerplate tread for outdoor or commercial/industrial applications as it provides needed traction. Some of our customers also like this modern looking tread on interior stairs.
Wood Tread Covers – Wood tread covers can easily be added to our base kits. Oak and Pine Tread Covers are available for interior use. We also have Cedar Tread Covers for exterior application.
Intermediate Spindles – Intermediate spindles are extra in between spindles added to the base kit. The base kit is “open-concept” which means there is only one spindle per step. We can add up to 3 extra spindles per step to minimize the space in between spindles in order to meet building code criteria.
Decorative Spindles – Some decorative spindle options available are collars, decorative, X design, safety spindles and also custom spindles.
End Caps – A strip of metal welded to the outside part of the step to give a more finished look. Also recommended for the larger staircases (5’ diameter and up) as it adds more structure to the step.
Custom Landings – Round, triangular and customized landings are also available in plain or checkerplate metal.
Parallel or L-shaped Railing – May be required if square landing is not secured on two sides i.e. corner application.
Additional Railing – Additional railing that may be required to enclose stair opening.
Base Plate Cover – Used at the base of the spiral to cover the base plate and bolts.
Wood/Metal Handrails – Our standard kits come with a durable vinyl handrail in black, brown or white. If you choose you can upgrade to a metal or wood handrail.
Larger Center Posts – Our standard kits have a 3 ½” center post which can be upgraded to a 5” center post to accommodate treads which are wider at the post (6”).
