- Stringer type is a Spiral beambeam that follows the form of a helix and is defined by a start point, center point and the rotation axis
Spiral beams can be concrete spiral beams or steel spiral beams. They can be used to create spiral staircases, complex architectural structures, and concrete parking ramps, for example.
Spiral beam can rise from the work plane or be flat. If the spiral beam rises, the total rise is defined between the start and the end point.
