Modern steel processing equipment can cut out intricate patterns in steel plate with extraordinary precision. At times, rolled beams, for example, have patterns cut in the web. Care has to be taken in the rolling process so as not to damage the cutouts.   Heavy rolled wide flange steel beams provide a strong yet simple mounting surface for circular rails of a Whirley Crane. Whirley Cranes are, by definition, free to rotate 360 dgrees while loading and unloading. Two large rings were rolled the “easy way” (y-y axis) and installed using W24 x 192 beams: a 32ft diameter outer ring and . . . → Read More: Rolling Steel Beams for a Whirley Crane 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 used to protect workers and to allow construction equipment access to an excavated area. Excavating and pile-driving . . . → Read More: Curved Steel Beams and Channels Used as Walers 100 tons of steel beams were rolled into compound bends (with both sweep and camber) and also formed into an S curve for the Animus Trail Bridge in Durango, Colorado. Several truckloads of W36 x 160# and W36 x 190# were rolled in lengths of 50-, 55-, 60- and 70-ft lengths and fit up within 1/16in. The . . . → Read More: Complex Steel Beam Bending for a Colorado Bridge A steel beam can be cambered by rolling it in a three roll bender, by ramming it with a hydraulic cylinder, or by applying heat with a torch. Cambering a steel beam, by any method, will increase its yield and tensile strength but decease its ductility and toughness. Data from research, however, indicates that the effects will . . . → Read More: How Cambering Steel Beams Affects Their Physical Properties Rolling beams and steel plate are processes most often used to curve metal. With the right machines, machine operators, and methods, however, the processes can also be used to straighten steel sections. In our plant today we are straightening three different shapes on three different machines for three different customers and for three different applications. In a plate . . . → Read More: Straightening Sections by Rolling Beams and Steel Plate
A convergence of events including the increasing acceptance of beam bending by cold cambering,
standardized design of steel bridges, and
increased availability of domestically produced jumbo beams
all contribute to making steel the solution for bridges. AASHTO (American Association of State Highway and Transportation Officials) has recently been revised its specifications to allow cold cambering of rolled beams. Article 11.4.12.2.6 has been . . . → Read More: Beam Bending by Cold Cambering Contributes to Making Steel the Choice for Bridges Bending of beams is often done to create curved steel monorails for material transport in factories and warehouses. Most commonly, the beams are curved the “easy way,” i.e. against the weak or y-y axis. Typically a trolley with a hoist hangs below the beam. Such transit systems are installed in new and existing plants. The person . . . → Read More: Bending of Beams for Steel Monorails 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 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 |
