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.
Your guys who help us are always on the spot and take care of all our requests very quickly. Great group! They have never been late or wrong... they do a great job for Albina. Please thank them for me.
I have to say; communication with Albina, is as good as it gets. Clarity was key to success, and I like that your shop reviewed our drawings as well, prior to bending. Our expectations were met, and we were given notification in advance about any concerns.
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.
