Arké SKY030 Spiral Staircase Kit 63" Dia. 99-5/8" to 120-1/2" Height Range 1000lbs. Cap. Black

The Sky030 63" diameter black spiral staircase is manufactured in steel with a particular treatment (Sendzimir process) that consists in galvanizing steel by using a small amount of aluminum in the zinc bath and producing a coating with essentially no iron-zinc alloy. This process guarantees high resistance and durability. In addition the metal is polyester powder coated. The final result is a staircase that is specifically made for outdoor installations because of its resistance to atmospheric elements. The landing platform for the spiral staircase is a triangular/universal design for a more versatile and easier overall installation. The triangular landing is illustrated in the installation instructions and the product data sheets listed for review. The staircase can be turned in either a clockwise or counterclockwise rotational turn if your entry and exit points need to be different. These can vary based on the overall height of your installation when measured from "finished floor" to "finished floor".

  • The height can be adjusted to a minimum of 83-1/16" and to a maximum of 148-7/16" by adding up to three additional risers (purchased separately, model K00000, K24117)
