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; 98% of the steel recovered from the demolition of steel structures is recycled. Some buildings today . . . → Read More: Structural Steel Bending Contributes to Sustainability        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 or bent, has grooves machined into the ends of the tube. In the case of the bent . . . → Read More: Aluminum Tube Bending for the Military 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: W6 x 24, W8 x 13, W8 x 35, W6x16, and W8 x 31. Some of the . . . → Read More: Bending of Beams: Curved and Green 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 (same plate thickness, same plate radius, same grade of steel), press brakes can usually “nose” the . . . → Read More: Steel Plate Rolling: on a Plate Roll or a Press Brake? 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. But some mathematical solutions are said to be more “elegant” than others, the beauty of which might . . . → Read More: The Knowledge Of, the Beauty of, and the Spirit of Steel Bending 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 the tubing was polished before it was rolled helically? What will it look like? A recent requirement . . . → Read More: Bending Stainless Steel Tubes for Circular Stair Handrails Mandrel tube bending of steel is a method for bending square, rectangular, and round tubing as well as pipe. As with any method of bending steel, mandrel bending, which is typically done on a rotary draw bender, has its strengths and limitations. The benefits of rotary draw bending with an internal mandrel (to keep the steel section . . . → Read More: Mandrel Tube Bending It is not hard to over-engineer steel section bending, but when the costs exceed the benefits, it’s time to go back to the drawing board. For example, when designing a simple, industrial push cart, a customer requested 2in schedule 40 pipe bending which was much heavier than was needed. The material alone would drive the costs . . . → Read More: Over-Engineering Steel Section Bending One aspect to consider regarding structural beam bending is how large loads will be shipped. Various states set criteria for the maximum height, width and weight that can be shipped by truck. In Illinois, for example, typical restrictions for a flat bed truck are a maximum of 13 ft. 2in. high, 102 inches wide and weighing . . . → Read More: Structural Beam Bending: Shipping Large Loads Specialty subcontractors who curve steel often enter into a dialogue with their customers about beam bending, channel bending and tube bending. The results of these discussions can determine which steel sections to use in a project and what the costs might be. And the earlier that these conversations take place between the specialty subcontractor, the structural . . . → Read More: Dialogues About Beam Bending, Channel Bending and Tube Bending |
