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 Read more…


When determining whether a given steel section can be curved without heat, it is useful to determine its section modulus and relate that value to the strength of the steel bending equipment. Section modulus measures the flexural strength of a Read more…


Structural steel bending, whether it involves angle bending, bar bending, beam bending, channel bending, tube bending or pipe bending, contributes to sustainability simply because it uses the most recycled material:  steel.  93% of the steel used in construction is recycled; Read more…


Aluminum tube bending has helped the military put out the oil refinery fires during the Iraq war.  45 degree elbows formed by mandrel tube bending connect straight tube sections across the desert to transport water. Each aluminum section, either straight Read more…


The bending of beams can contribute to sustainability as is evident in the mile-long walkway at Dos Lagos. The walkway is made of 213 pieces of curved beams weighing a total of 45 tons of steel formed by multi-radius bending:  Read more…


Steel plate rolling can be done either on plate rolls—machines that incorporate three or four rollers to form curved shapes—or “bumped” with a radius die on a press brake.  Both methods have their strengths and weaknesses.  Everything else being equal Read more…


Steel bending is a discipline, and a wise teacher once said that any given discipline has three aspects to it:  the subject matter itself, an aesthetic, and a spirit. For example, mathematics is a discipline about numbers, computation, formulas, etc.  Read more…


Questions about surface finish often arise when there is a requirement for bending stainless tubes for circular stair handrails.  Will the helical tube bending process damage the finish?  And what if the project requires bending polished stainless tubing?  What if Read more…
