Architects, engineers and fabricators have asked whether tubing can be formed with both camber and sweep. The answer is yes. An example of tube bending that induces both camber and sweep can be seen in the sinuous pedestrian bridge in Longview, Read more…


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 Read more…


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 Read more…


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 Read more…


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 Read more…


Mock-ups involving structural steel bending and steel plate rolling can ensure that the resulting structure will meet everyone’s expectations. Particularly because curved steel is so often incorporated in exquisite architecture, the demands placed on companies that specialize in bending and Read more…


At the North American Steel Construction Conference held on May 11 to May 14, 2011, we learned from Bill McEleny, Director of the National Steel Bridge Alliance, that the AASHTO construction specification has recently been revised to allow cold cambering Read more…


The American Institute for Steel Construction (AISC) specifies the standards for steel construction in its Code of Standard Practice for Steel Buildings and Bridges (COSP).  The COSP defines the “the trade practices that shall govern the fabrication and erection of Read more…


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 Read more…


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 Read more…
