Albina Provides Rolled Steel Canopy and Exceptional Customer Service for St. Jude's Hospital
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. Operations Mngr, Cundiff Steel Fabricating & Erecting stjude 002.
Another Customer Quote of Appreciation
"The quality of your work and the extra efforts taken to expedite this project make it hard for any other forming company to get in the door. You’ve earned our business and my thanks."                                                  -Progressive Steel Industries, Ltd., British Columbia
Museum of Flight in Seattle, Washington
Albina Pipe Bending rolled 128,894 pounds of 5" Sch120 and 5" Sch40 pipe (tilted at 45 degrees)to help create a striking 340-ft steel pedestrian bridge linking the current Museum of Flight (Seattle, WA.) to a remote exhibit space and future development site across a busy traffic arterial. The radiused bend of the hoops varied from 22 ft at the center of the span to 19 ft at the tapered ends. All of the material is Architecturally Exposed and this bridge is a perfect example of why steel is the sustainable, available, fast and econmical choice. Precast structural shapes and cast-in-place concrete solutions were studied, but the narrow apeture through which the structure needs to pass, above the roadway clearance and below the power lines, limited the amount of structural depth that could be accomdated below the bridge deck. Using a steetl truss allowed the structural depth to surround the partially enclosed interior space and also maintained consistancy with the existing museum's architecture. The bridge deck was also originally specified as cast concrete over metal deck, but the weight of the material remained a problem, so once an extruded aluminum deck plank was identified, the steel could be reduced in weight, resulting in a savings to the project and a more appealing and eye catching design.

How HSS reacts to the bending process
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.
