Architecturally designed pedestrian bridges and walk-ways are often erected at transportation stations, universities, museums, business centers, and state parks. Most often, these curved steel bridges are constructed of bent or rolled structural steel including, pipe, square or rectangular tube steel, channel and wide flange. It depends on the application, the load requirements the AESS (Architecturally Exposed Structural Steel) requirements, and fabrication specifications of the project to determine which type of structural steel will best fit the needs of the project.
Here is an update on the bent structural materials used to create a custom treehouse.
Albina bent and fabricated various structural materials to create the floor supports and decking for a custom tree house in Sammamish, Washington. Materials used included:
a) 3-1/2″ Sch80 and 5″ Sch80 Bare Pipe fabricated complete per drawings with brackets cap welded to ends
b) 1/2″, 3/4″ and 3/8″ Rolled Plate
c) Tube Steel 8″ x 4″ x .250″ Wall A500 GR B
d) W6 x 15# A992 and W8 x 15# A992 Wide Flange
Engineering News Record: California awarded the Happy Hallow Pedestrian Bridge in San Jose, CA. an Award of Merit in the small projects category. Completed in March 2012, the bridge is the first of its kind in Northern California and consists of twin 270-ft identical spans. These were constructed using only two rolled sections for the arch ribs and for the tie girders and cross bracing. Albina Co., Inc. rolled 140,000# of W14 x 109# A709 50W the Easy Way to a 225 ft. radius and 90,000# of WT9 x 38# A709 50W split from W18 x 76# and then bent to various radii. A single cable size (3/4 in. dia) was used for both spans.
The National Steel Bridge Alliance (NSBA) is a division of the American Institute of Steel Construction (AISC). The NSBA’s mission is to promote steel as the preferred material for bridge design and construction and to increase steel’s share of the bridge market. Albina Co., Inc. is one of the leading structural steel fabricators for steel bridges that contain bent or curved structural members for architectural, structural or ornamental applications.
The NSBA brings together the structural steel fabricators and producers with agencies and groups who have a stake in the success of steel bridge construction, including representatives from AASHTO, FHWA, state DOTs, bridge consultants, erectors, and representatives of the coatings, fastener, and welding industries. The NSBA assist with bridge design specifications and provides technical assistance and reviews throughout the drawing/specification process.
The World Bridge Symposium is taking place March 26-28th in conjunction with the North American Steel Construction Show, The Annual Stability Conference, and the Technology in Steel Construction Conference at the Metro Toronto Convention Center.
The 2014 NASCC (North American Steel Construction Conference) will be held at the Metro Toronto Convention Center in Toronto, Canada March 26-28th. The Steel Conference is the place for engineers, fabricators, detailers and erectors to learn about structural steel design and construction, to interact with their peers and to see the latest products for steel buildings and bridges. This year, in addition to the NASCC exhibit hall, three additional conferences will be incorporated into the show: The Annual Stability Conference, The Technology in Steel Construction Conference, and the World Steel Bridge Symposium. There will be various technical seminars, networking opportunities and product showcases tailored towards structural engineers, detailers, erectors and fabricators alike. Albina Co., Inc. will have an ad featuring bent steel projects in the show’s premier industry publication “Modern Steel.”Modern Steel NASCC Show
Albina Co., Inc. had the opportunity to feature several of their high-profile bent steel projects in many of the national trade publications during the month of February. NOMMA’s (National Ornamental of Misc. Metals Association) Annual Buyers Guide features several spiral, circular and helical staircases using materials such as plate, pipe, tube and structural members. It also highlights some of the decorative gates, fences and signage that we specialize in. One new product that Albina is offering includes complete handrail kits. The handrails are bent and trimmed per the customer’s drawing, the mid-rails trimmed and coped, and the assemblies are supplied as individual parts or fabricated complete!

Albina Pipe Bending Co., Inc. prides itself on top quality customer service and providing top quality bent steel for all jobs no matter how big or small. We recently completed a small bridge and art project for a customer out of California. We received the following feedback: “Just wanted to say a quick “Thank You” to you guys for your work on the project. It is a pleasure to deal with Aaron Hughes. This was a small project with a quick turn around and he kept me informed the entire time. I cannot tell you what that does for my scheduling.”
