Rolling (aka "Pyramid Rolling") is the typical method of curving steel for construction related projects and is usually the most economical bending method for curving members to larger radii. A steel member is placed in a machine and curved as it moves through the three rolls. All three rolls are independently rolling / spinning and two of the rolls can move adjacent to the material creating more or less pressure on the material, resulting in tighter or larger radii. Roll bending is also commonly called "pyramid rolling" because of the three rolls' pyramid arrangement. Different radii are formed when the distance between the three rolls in relation to the material is manipulated before each successive pass. To successfully roll bend to required radii the material often makes multiple passes through the rolls.
Just wanted to say a quick Thank You to you guys for your work on my project. It is a pleasure to deal with Albina. This was a small project with a quick turn around and you kept me informed the entire time. I cannot tell you what that does for my scheduling. Thanks again!
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).
Curved steel members don't just "come that way" from the mill. Curved steel members are produced from straight lengths of material and are bent per your specifications.
Albina Co., Inc. produces the highest quality curved steel products in the steel industry and provides the most reliable and professional customer service experience.
