Designers, architects, owners, engineers, structural steel fabricators – anyone who is interested in using curved steel shapes in their buildings, equipment or other structures can benefit from entering into a dialogue with companies that specialize in curving steel.
While there are copius manuals and guides for what pipe can be bent successfully on rotary draw benders, there is . . . → Read More: Curving Steel Shapes: The Importance of Record Keeping
When performing steel plate rolling and bending of higher strength steels, you will have two main considerations:
1. The tonnage/capacity of the machine
2. The spring back of the material after pressure is released
The tonnage is fairly linear in proportion with the yield strength. So if the yield strength doubles, so does the tonnage required to bend it. Most bending . . . → Read More: Steel Plate Rolling and Bending of Higher Strength Steels
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.
There is not a mathematical formula for determining the minimum bending radius of steel sections. To better explain this, lets look at bar bending. Steel is curved using a cold-roll bending process. Steel sections are put into a section bender (also called an “angle roll”) with a three or four roll configuration. Rollers put force against . . . → Read More: Minimum Bending Radius When Bending Bars of Steel
Probably the most common question we get from new customers is, What is your capacity for bending, particularly for the bending of beams. We have a quick and easy answer: W44x290# beams the “hard way” (x-x axis) and the “easy way” (y-y axis) as well as W36 x 848# the “easy way”—all on the world’s largest . . . → Read More: What is the meaning of “Yes, we have the capacity to bend that beam”?
