SPECIALTY STEEL BENDING: SPIRAL CIRCULAR & HELICAL BENDING


A spiral, circular or helical bend occurs in a plan view with rise in elevation.


Why Choose Albina as your Spiral Bender?


Albina doesn’t split HSS prior to bending and then weld the sections back together to meet your needs, our HSS members are bent as HSS members.


Albina doesn’t fill your HSS with other structural members. We are able to bend HSS members without adding extra material and weight and are still able to meet or exceed your quality requirements.


Albina will bend your HSS stringers out of HSS material; we don’t make "built up stringers" out of plate.

Developed Elevation View


The developed elevation view shows the component in a flattened or unwrapped view. The degree of arc in plan relates directly to the overall run in developed elevation.
