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…


Some years ago, the Steel Quiz of Modern Steel Construction asked “Which of the following camber ordinates for a 30ft W16x26 beam are not recommended? a. ¼ in., b. ½ in., c. 1-1/2 in, d. 2 in, e. 5 in.” 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…


As far as the bending of pipes is concerned, both grades of steel can be curved equally well. The differences derive from the applications for each grade. A53 is pressure tested for liquid and gas flow so is best suited Read more…


OEMs often face the decision of whether to make component parts in house or to subcontract them to outside vendors. An analysis of a company’s core competencies often dictates what items to outsource and what to retain. Furthermore, a company’s 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…


When considering how information is communicated between different firms/companies, CAD or Computer Aided Design is probably one of the biggest milestones in the history of Industry. In the bending/rolling industry, the most important dimensions to convey of any part or Read more…
