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.
Of course a picture is worth a thousand words, but what happens when you don’t have a picture? Customers call from the field to describe how they want their steel curved. We love everyday references to help us describe the section bending:
–The “belt around your waist” (easyway flat bar) versus the “flat washer” (hardway flat . . . → Read More: When There Are No Pictures to Communicate Specifications for Bending Steel Sections, Use Everyday References
One of the most commons mistakes individuals make when ordering structural steel rings or steel sections is caused by the confusion of radius and diameter. When an individual is ordering the service of curving steel and has successfully communicated the orientation of the part (e.g. hard way or easy way), it is always wise to ask again, Is . . . → Read More: Bending Steel Sections: The “D” Word
A material take-off supplied by a Steel Fabricator to a subcontractor who specializes in curving steel yields quick and accurate curved steel quotes. What is a curved-steel, material take-off? The Steel Fabricator sends in a list of what they need curved and how. The information needed is basic: the piece mark; the quantity; the . . . → Read More: Curved Steel Sections? Material Take-Offs Yield Quick and Accurate Quotes
Some companies that specialize in rolling and bending metal for construction and/or for component parts for equipment strive for continual improvement in the curving process to yield improved curved metal products. These cutting-edge companies build on decades of experience that makes them a valuable resource for their customers.
Their customers, however, sometimes do not know exactly what . . . → Read More: Specifying Curved Steel Sections
My older son, Tyler, is a sophomore taking Geometry and just failed his trigonometry pop quiz on sine, cosine, and tangent. Panicked for his test the next day, we had a great teaching opportunity. He knew the rule soh-cah-toa (sine is opposite over hypotenuse…etc), but did not know how to apply the rule.

The most important thing to establish prior to any work being done on a multi radius bending of steel sections is to work hand in hand with your customer and even more importantly the detailer who has drawn up the prints. Multi radius pieces are very possible to fabricate and shouldn’t be immediately thought of as a . . . → Read More: Working with Detailers to Achieve Multi Radius Bending
