Straight and Curved Unistrut channel (also called ”Flexstrut”, “Kindorf”, “Strut channel”, “SuperStrut”, “Strut”, and “Metstrut”), along with a wide variety of connectors, can supply light structural support for electrical, mechanical, heating, ventilating and air conditioning systems. Although typically P1000 is Read more…


The term “non-commodity” is used to describe steel shapes when the size and alloy in demand is not produced for distribution to the masses. The demand for these specialty steel members does not occur with enough frequency for rolling mills Read more…


Representative of the Elks USA located in Chicago via e-mail:  “Can you supply two 40in diameter rings of 3in channel in stainless steel rolled with the flanges out for the reconstruction of our flagpole base?” Estimator of the Bender Roller Read more…


Of all the structural steel sections that are curved in a variety of ways, one of the most difficult to curve is the steel channel rolled against the strong axis. When bending a channel the “hard way” in a three-roll Read more…


Of all the structural shapes – angles, bars, beams, channels, tees, pipe and tube – everything else being equal, the most difficult shape to bend is channel the “hard way,” i.e. against the strong axis.  As you can imagine, pressing Read more…


A rotary channel splitter is a device that cuts with revolving steel wheels.  A blade that is stationary rotates to push the channel against another blade that causes the material to experience highly localized shear stresses between the two blades.  Read more…


Bending aluminum channel can be difficult.  Under extreme conditions, it tends to crack.  Bending aluminum channel into a helix is even more of a challenge.  With the right tooling, machine, machine operator and process, however, some impressive bends can be Read more…


Steel beams and channels rolled into a circle and installed horizontally are often used to reinforce soil in trenches.  These rings are called walers.  Typically, steel sheet piling is driven into the ground behind the walers.  This creates a ring template Read more…


When one considers ways to bend a large channel flanges-out to a minimum bending radius, doing a mandrel bend is one alternative.  A recent requirement was for more than 200 rolled channel, bump protectors to cover cement columns in an Read more…


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 Read more…
