Arkè Staircase Kits

Sky 030

The SKY030 spiral staircase, available in 3 diameters – 47, 55 and 63 inches – 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 standard SKY030 staircase kit is adjustable in height from a range of 99 5/8” to 120 ½” and with additional components, can be extended to a maximum height of 148 7/16” or to a minimum of 83 1/16”. The standard kit with 13 treads, including a universal landing, installs with a 360° turn. By adding or subtracting treads the rotation will change by approx. 30° per tread.

Additional riser kits can be purchased separately.

The SKY030 stair treads are made of solid steel, ventilated to provide a slip-resistant surface even when wet. The handrail is black PVC for all staircases.

The stair can be used in square or mezzanine applications. To allow for proper installation and full clearance, the finished opening MUST be at least 2 INCHES GREATER than the diameter of the staircase kit.

To complete your project a Balcony Rail Kit available.  The Balcony Rail Kit comes complete with 10 balusters (length 39.37”), handrail, and all the necessary hardware to complete a 47” (width) installation.  The Balcony Rail Kit is available in the same colors as the SKY030 staircase kit. 

Safety Bars are available in a set of 12 to close off the back of the treads (this way a 4” sphere will not pass through).

The 63” spiral stair has been designed to meet IRC requirements.

Each SKY030 staircase kit is shipped complete with detailed assembly instructions to assist in your installation. The stair has a 1-year warranty for manufacturing defects.
