Purchasing material from a single rolling at a steel mill allows your bender/roller to provide a more consistent and uniform product. Different mills produce steel that, while the same size and shape, may be produced in a different fashion. Even within the same mill, different batches will bend differently due to variations in material composition.

In many cases, steel bending can minimize welding and reduce material waste on a component part for an OEM (original equipment manufacturer).
For example, an OEM was designing a gear cover for pumps. The component part was a 1 x 1 ½ flat bar curved the easy way (against the weak or y-y axis) to form what . . . → Read More: Using Steel Bending to Minimize Welding and Reduce Material Waste.
Steel bending is often subcontracted to companies that specialize in providing curved steel sections sometimes called “rolling houses.” The question arises, which party should supply the steel—the customer or the rolling house? There are several factors to consider.
Where can the steel most easily be procured? Even if the rolling house adds a markup to the cost . . . → Read More: When Steel Bending Is Subcontracted, Who Should Supply the Raw Material?
I have frequently lectured and written about structural steel bending for architects, engineers and structural steel fabricators as well as for undergraduate and graduate school engineering students. In the dialogue that followed the presentations, I have been asked a number of questions.
Some of these questions are best answered by the rolling houses (companies that specialize in . . . → Read More: Structural Steel Bending Questions From Architects and Engineers Answered Here.
Structural beam bending is often done for the purpose of cambering. (Camber is the amount of deflection provided in the opposite direction of loadings.) An excellent article in Modern Steel Construction, $ave More Money (March 2008), states that “the minimum length of a beam to be cambered is about 25 ft. Why? Because the fabrication jig . . . → Read More: Structural Beam Bending: $aving More Money When Cambering Beams
Whenever I talk to architects and engineers about bending beams, bending pipes, or any other steel section bending, three questions usually come up:
Is it structurally sound?
Is it too expensive? And
Is it readily available to meet a demanding construction schedule.
Is it structurally sound?
Writing specifically about steel beam bending, Reidar Bjorhovde addressed this question in the Engineering Journal/Fourth . . . → Read More: Curved Steel in Construction? No worries!
