General Characteristics

Backbone has been designed around a common basic module through which both linear and curved structures can be created. The capacity to rotate around the vertical plane, the use of rings to adjust the step tread and a wide range of accessories means this is a very flexible system. A double Backbone option is available to create linear stairways, with or without landings. This offers the potential to span greater widths, achieve higher resistance, remove the need in some cases for supporting elements and reduce the dimensions of the glass tread.
