Use our Online Tools to Calculate Bending Dimensions

For all our customers that need assistance in calculating bending dimensions or material take-offs for bending.  Look no further than Albina’s bending calculators / Curve Calculators.  Albina’s bending calculators allow end users to calculate the following critical bending data:

  1. How to calculate the arc of a bend or curve with our Arc Calculator.
  2. How to calculate the degree of a bend or curve with our Degree Calculator.
  3. How to calculate the Mid-Ordinate (MO) / Rise of a curve or Arc with our Mid-Ordinate Calculator.
  4. How to calculate the radius of a curve with our Radius Calculator.
  5. How to calculate the ovality of a round section after bending with our Ovality Calculator.
  6. How to calculate the critical dimensions of a stair stringer with our Stair Stringer Calculator / Spiral Math Calculator.
  7. How to calculate the degree turn in plan view for a spiral staircase (spiral stringer).
  8. How to calculate the degree of pitch for a spiral staircase (spiral stringer).
  9. How to calculate the arc length for a spiral staircase (spiral stringer).
  10. How to quickly determine the amount of straight or tangent material needed to successfully bend a length of material or part.

Albina’s calculators can be found here:  https://www.albinaco.com/calculators

Albina also specializes in plate bending, not just HSS, Pipe, Tube, and Structural Steel bending.  Countless customers come to Albina for our plate rolling expertise, including bending plate into a cone configuration.  Many customers require a cone calculator.  There are many cone calculators available, but we typically use a calculator located here:  https://i-logic.com/conecalc/.  Not only will this calculator provide the end user with the critical cone dimensions, but also the cone flat pattern.

"Daunting Curves Ahead"- Article in O & M Metal Fabricator
"Daunting Curves Ahead"- Article in O & M Metal Fabricator

A recent issue of O & M Metal Fabricator Magazine, produced by NOMMA, features a case study written by Jeff Fogel with input from key members of the Albina Team, on the great spiraling feat it took to create the spectacular spiral staircase at the American Airlines Headquarters in Fort Worth, Texas.

We spiral bent Tube Steel 16″ X 16″ X .625″ WALL A500 GR B bent down to a an 18 foot radius, using our induction heating process to create the spiral stringers for the staircase. In addition to the 16″ square, we produced another set of spiral stringers consisting of Tube Steel 14″ x 6″ x .625″ wall REALLY tight, exposed and bent to a 5′-6″ radius on a 45° pitch. These are the type of bends that ONLY Albina can do! The 1.7 million-square-foot complex, dubbed the “Trinity complex,” consists of four seven-story buildings. It cost nearly $300 million to build and houses over 6,500 employees. There were 10 tower cranes on the project and more than 1,000 construction workers on-site during the peak of the project.

NEW- Ovality Calculator Now Available on Our Website
Ovality is simply how “out of round” a round material is. The new ovality calculator determines the % of ovality (i.e. the % the material is out of round). All round material has a certain amount of ovality (even as straight material) nothing is PERFECTLY round, mills will produce material to an ovality tolerance. When bending round material, the material will slightly oval. The material theoretic OD, the wall thickness, the radius the material is bent to and the bending method (i.e. how is the material bent) will all impact the final ovality of bent round material. Customers that are using pipe for pressure retaining systems, heat exchangers, industrial applications, boiler tubes, etc. are all concerned about the ovality of round material after bending. The ovality calculator is a great addition to our already vast offering of general bending calculators and spiral math calculators available online.

Albina Co., Inc. Provides End Users With Tools to Successfully Quote and Understand Their Curved Steel Project
Albina Co., Inc. provides a plethora of tools on their website to allow end users the ability to not only make important steel bending calculations with the bending and spiral bending calculators, but we also provide a number of conversion charts, weight and dimension grids and reference guides. We want the end user to understand what we are quoting, why we need the information that we do, how we quote and ultimately we want the end user to understand the nuances of using curved steel on a project. We also provide calculators to aid in determining tangent materials and bend tolerances for different material types, sizes and bending processes. Visit our "Calculators" page to gain easy access to these tools. Bookmark the page for future reference!
Spiral Staircase for "The Hopservatory" at Worthy Brewing in Bend, Oregon
Albina Co., Inc. recently completed 14,000 lbs. of bent steel to create a beautiful spiral staircase at Worthy Brewing in Bend, OR. Bent steel materials for the project included: MC18 X 42.7# A36 spiral bent lengths with flanges in and lengths with flanges out were bent down to a 9 ft plan view radius! Landing pieces were also spiral bent down to a 9’ 8” radius. C15 X 33.9# A36 for the inside landings were spiral bent down to a 8’ 9” outside radius (plan view). Bend, Oregon is located on the eastern edge of the Cascade Mountain Range along the Deschutes River and is a popular tourist town known best for the many outdoor activities offered and world famous micro-brews. Worthy Brewing Co. broke ground on Feb. 24, 2012 off U.S. Highway 20 on Bend’s east side — it’s Bend’s 1st east side brewery – and with a beer garden, hop garden, and Hopservatory. The spiral staircase winds up to The Dome at the top of the rotating Hopservatory where visitors can view the cosmic skies through an OGS 16” RC Reflector telescope.

Spiral Coils for Industrial Heat Exchanger
Albina spiral coiled ½" OD X .065" WALL stainless steel tube heat exchanger for an industrial application. We were supplied with only the existing coil to reproduce from. The coils were bent in one continuous piece that spirals down on the inside and then steps out and spirals back over itself. The sheet between was not needed to complete the bends but was left in place to match the existing design.

Mobile Friendly Website Now Available!
In recent news, we released a “mobile-friendly” website (www.albinaco.com) that provides fabricators, architects, engineers and many more with vast interactive calculators, reference materials, and capacity charts to assist with all of their bending calculations and provide answers to their technical questions. The “mobile-friendly” site is completely responsive and is easy to use and navigate on your mobile devices as well as your desktop. Web Albina Co., Inc. offers custom bending calculators designed to assist customers with required bending calculations, and to provide bending tolerances and tangent material requirements needed to accurately bid a job. In addition to the general bending calculators, Albina also offers a Spiral Math Calculator to allow customers to enter known data for spiral stringers, automatically calculate Degree of Pitch and Arc Length, and save the calculated information in their files for future reference or submit a report directly to Albina Co., Inc. for a quote! It is that simple. Additional highlights include a virtual tour of the company, material capacity charts and bending profiles, brochures, technical articles, industry links and numerous work examples including professional photographs of installed projects and videos of actual bending processes. Albina has several easy to use forms for requesting information or for obtaining a quote. Online ordering is also available through Albina’s site for Duct Systems and Component Parts and a secure login can be obtained to view pricing and place orders from your smart phone or desktop. “The driving force behind releasing a new “mobile-friendly” website was to create a seamless user experience for our customers no matter what device they use to access information. We wanted to provide an informational tool rich with easy to read capacity charts and stunning visual images to give the user a quick view into our capabilities. We also wanted to provide accessible tools to assist users in their daily job functions.” –Brian Smith, President Albina Co., Inc.
