Rotary draw bending is a cold bending method where the member is clamped to a rotating bend die and drawn around the bend die. The tailing tangent is held against the bend die by a pressure die, and the bend die rotates until the desired geometry is formed. A mandrel is often placed inside the member to restrain cross-sectional distortion during the bending process. Bends can also be formed with special draw-bending equipment where deformations are controlled by tensioning along the member axis. Rotary draw bending is commonly used to form small radius bends in smaller-size round, square and rectangular HSS members. Specific tooling is required for each member size, shape and bend radius; therefore, this method is best suited for projects requiring many identical bends. This bending method is primarily used in the machine and parts industry (Weisenberger, 2016) and for piping (Riviezzi,1984). The maximum degree of bend is 180°, but the minimum bend radii of round HSS is approximately 50% smaller than that of other cold-bending methods (Riviezzi, 1984).

A shout out to these awesome guys for all their hard work and dedication! The shop is super busy right now and they are churning through the work creating top quality steel bends for our customers! We are so busy that we are looking for qualified candidates that want to join us in our steel bending adventures. If you are interested in learning more about the available positions in our shop, please contact HR firstname.lastname@example.org.
We recently worked with a customer on a unique project where they required curved Unistrut. We were able to successfully roll 1 5/8″ X 1 5/8″ GALVANIZED UNISTRUT the hard way to a 168” radius. A unique material for rolling! We figured out a way to maintain the shape while rolling and were able to bend 116 lengths! We received a comment from our customer that “no one at the jobsite had ever seen Unistrut curved before!”
Check out the cover spot and three page feature article on Albina Co., Inc. in the June/July West Coast Edition of A2Z Manufacturing Magazine. Pages 24-26! Portland artist Devin Laurence Field produced the laser-cut stainless steel flame sculpture and Albina Co., Inc. bent 18″ STD A53B ERW 10 lens x 40 ft down to a 42 ft radius for the sculpture.
We had such a great time working with Linda and Kim to highlight and showcase all of the amazing curved steel projects we have done in Oregon, Washington, and California. Some projects featured in the article include:
Check out the two-page feature article on Albina Co., Inc. in the May Southwest Edition of A2Z Manufacturing Magazine. We had such a great time working with Linda and Kim putting the article together.
The article highlights several projects that we have participated in specifically in the states of Arizona, Nevada and New Mexico. Our company history, philosophy and future goals are also touched on in the piece.
We recently completed a project consisting of 400 pieces of bent tube steel 4″ X 4″ X .375″ WALL A500 GR B for a customer on the east coast. All parts were cut and trimmed by Albina to a 1/16” tolerance. These bent parts will be used on equipment for the timber industry.
We recently completed a job bending some rock guard frames out of 1″ SCH80 6063-T52 Aluminum. Albina cut and bent the aluminum to net 500 pieces. All of the pieces were bent on a 5″ center line radius. It was quite an amazing site to see them all packaged and ready for shipment in our yard!
