Albina and Cundiff Steel Fabricating & Erecting provided 36,000# of TS 16" x 8" x .375" wall, TS 16" x 8" x .500" wall, TS 10" x 8" x .250" wall, and TS 16" x 16" x .375" wall all AESS for a canopy at St. Jude's Hospital. Cundiff Steel had the following comments about working with Albina: " I want to thank you guys for sticking with us on this project. It drug on for a long time and Aaron rebid it several times as we went through headache after headache with the engineers. I feel he went above and beyond to help us get this project on track. It took a lot of correspondence back & forth to get everything dialed in & Aaron was very helpful through all of it. The lead time from finally getting you approved drawings to us receiving the material was much less than we expected. Also, I appreciate the time Aaron took when I visited to show me the material and provide a tour of the facility to see how it all works. Thanks again for the great service." CHARLIE PISCOPO, V.P.

Without some sort of internal support HSS material rolled / curved will result in a certain level of distortion. The faces of the material will try to concave, wrinkle and crush during the bending process. HSS reacts to the bending process by collapsing inward as a result of compression across the horizontal faces and the inside face of the material. Severity of deformation is increased when using thinner wall material and/or bending to tighter radii. Deformation of tube faces is also dependant on material sizes and direction of rolling (i.e. the Hard-way or the Easy-way) when bending rectangular tube steel. The inside face will deform more significantly when bending rectangular material the Easy-way versus the Hard-way. The outside face of the material will always deform the least regardless of bend direction. In extreme cases, certain faces may not only collapse inward, but can result in alternating inward and outward collapsing as larger wrinkles throughout the bend section. Albina Pipe Bending Co., Inc. has implemented an internal support system that reduces concavity, minimizes distortion, allows for tighter radii and reduced deformation and twist. By filling the void in tube steel’s interior, internal support restricts the amount that material can collapse, resulting in greatly reduced deformation using thinner walls to tighter radii when compared to materials bent without internal support. Internal Support is designed to provide higher quality bends to the end user by meeting your Architecturally Exposed needs. Albina Pipe Bending Co., Inc. feels strongly that bending options must be supplied to an end user. It is critical for end users to understand that increasing the wall thickness is a solution BUT NOT the only solution if you demand high quality HSS bends. It is important to Albina to provide customers with cost effective solutions by providing a number of bending options (i.e. roll bending with or without internal support, cold increment bending and hot increment bending) resulting in various end products.
