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.

I was talking to a potential customer yesterday about fabrication of some complicated work, most of which included rolling. When asked about maintaining tolerances, I could say without hesitation that Albina would provide a product that exceeded expectations. It's good to know you have a partner that can carry their weight when bidding tough projects.

We got the first shipment of the curved tubes. We pulled 3 at random; they dropped into the fixture or were very close (so close as to be a non-issue) and were perfectly flat. Also, none of the ones I saw on the top of the pile appeared to be scratched up requiring us to spend extensive amounts of time grinding them to meet our customer's cosmetic needs. My supervisor was actually giddy. He said they were going to be a joy to work with. You made his day (and therefore mine).
