Spiral stairs built to last.

Model 64 HDSK

This stair is a 64" diameter “heavy duty" bolt together kit stair. This stair is ideal for a customer wanting the fully assembled look with insufficient space to bring in a one piece fully assembled stair.

The hand rail is a # 200 - 1 1/2" round 16 gauge tubing. The main and center balusters are a # 369 - 1/4" round solid bar treaded at the bottom (spaced less than 4" apart). The treads are made out of a 3/16" checker plate material and welded to a 3 1/2" I.D. schedule 40 sleeve which installs over a 3" I.D. schedule 40 round center column. The stair is fabricated in the shop, disassembled, and painted a red oxide primer. This stair does not require cutting; modification or special tools to re-assemble. The final finish is applied by the customer after the installation.
