Sierra Stair Works, Inc.

Custom Wood Staircases & Spiral Stairs  

 Sierra Spiral Stair

Why you should choose a Sierra Spiral Stair Kit~

Our custom designed spiral stair kits provide easy installation with our unique locking tread system. Each tread is 1-3/4" thick which makes the spiral stair more stable with less sway. In many spirals the load is supported by the center pole. In our spiral stair the treads support the load in the same way a traditional stair system does. The layout for our spiral stair is flexible in that it can be rotated to accept traffic from any point you desire. The stair can be built with a clockwise or counter-clockwise rotation.

Sierra wood spiral stairs can be built in 4' diameter, 5' diameter, 6' diameter or 7' diameter sizes. If you need help in determining which spiral will work in your application, please contact our office at 916-652-2800.
