Stairways, Inc. will have a spiral stair model to meet any need. If economy is your need and residential codes will not have to be met, a standard spiral stair kit could be your answer. Going up to a deck, down to a basement, or in a shop, standard spiral stair kits can be purchased for less than what a straight wood stair can be built. A spiral stair will not use the space of a straight run stair and adds visual interest. Spiral kits are sturdy and inexpensive to ship. A standard spiral stair kit ships with a steel rail, smooth steel steps, 3/4” square balusters, a landing with rail on the landing…everything needed for a quick and inexpensive installation. Contact Stairways, Inc. for more information if economy and quality is needed for your project.
