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 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.

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.

The Buddy Holly Hall of Performing Arts and Science in Lubbock, Texas is a 220,000 square foot state-of-the-art campus featuring two theaters, event space, a full-service bistro and a ballet academy under one roof. Albina bent various materials for the signature spiral staircase in the Christine DeVitt Lobby. See LINK IN OUR BIO to get a sneak peek inside!
