Manufacturing a helical staircase
The precise curves of a helical staircases means the design and manufacturing process requires a level of skill, expertise and precision beyond that needed for a straight staircase. A comprehensive digital site survey is taken using state of the art measuring technology that is accurate to within 80 microns to capture the precise details of any underlying construction.
This is used to create a detailed 3-dimensional digital CAD model by a highly skilled design team to allow for the meticulous manufacture of curved components or a complete bespoke helical staircase. This is achieved by dividing the more complex curves and features into parts and running them through a computer simulation to makesure that each component is correct and accurate. These accurate models allow skilled craftsmen to build a forma (see photo) which duplicates the exact curvature required around which the curved components are built.
