Custom spiral staircases are something gives a unique “twist” to any structure. Spiral staircases are not only used to give an aesthetically pleasing look for decorative staircases but also for practical space conserving designs. Although there are turnkey bought off the shelf staircases, most of the time those are not going to work for large scale or one of a kind projects. Top notch bending and rolling companies have developed techniques along with technology to take spiral staircases to new heights.
Custom spiral staircases can be created out of a number of materials. For the structural curved stair stringers, materials that can be used include square and rectangular tubing and round pipe, as well as channels and curved plate. Unlike a level bending process which can usually be done on a single machine, the helical bending process for spiral staircases sometimes uses multiple machines to get the desired radius and pitch. Depending on the material to be used, a helically curved structure may require special care and preparation to improve accuracy and minimize deformation that might affect installation and fabrication on site.
It is not only the material of stair stringers that can be customized. There are many other aspects that can be made to fit the customer’s needs. Some spiral staircases call for varying tread sizes, landings, or to have an elliptical shape. These specialized design features can cause a complex change to the geometry of the helix, requiring skilled engineers and operators to take special care of the rolled pieces.
When designing a custom spiral staircase, it is smart to call a knowledgeable bending company and speak with an engineer or estimator to see what is plausible for construction. Working together with a bender/roller company can allow you to create a one of a kind spiral staircase for your next project that is sure to draw attention and praise.
