The request was for 15ea. 8in outside diameter aluminum pipe rolled to an 83ft 7in center-line radius 15ft long and for 9 more rolled aluminum pipes to a 47ft 11in centerline radius 15 ft. long. And the customer wanted the aluminum segments to be shipped to Chicago’s McCormick Place. We asked what all this was . . . → Read More: Rolling Aluminum Pipe for the NATO Summit in Chicago        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 Everyone recognizes the good that is done when someone does volunteer work, contributes to a charity, helps his neighbor. Some years ago, Ted Turner, the founder of CNN, gave a billion dollars to the U.N. In a television interview, a reporter asked him if he could have done more good by reinvesting that money in one of . . . → Read More: What Good Are You Anyway? The price of energy including gas is a hot topic these days. Not only does it cost almost $100 to fill up your SUV, but the price of everything processed, manufactured and/or transported (which is about everything) will cost more because of an increase in energy costs. Furthermore, economists have calculated that a 25 cents increase in . . . → Read More: How Does the Price of Energy Affect Those of Us Working with Steel? If you have a curved segment that is less than 180 degrees, you need geometry to verify the radius because you can’t directly measure the diameter. Begin by selecting an appropriate straight edge to use as the chord—the longer the chord, the more accurate the measurement. Push the straight edge up to the inside of the curve. At the . . . → Read More: How to Check the Radius on a Curved Segment. Chicago Metal Rolled Products proudly provided 133 tons of curved steel pipe for the 2012 IDEAS2 Merit Award winning project: Great American Tower at Queen City Square Roof-Top Tiara, Cincinnati, Ohio. The 13-story Tiara brings the height of the building to 665 feet, making it Cincinnati’s tallest building. If you ever watch the TV series, Harry’s . . . → Read More: A Crowning Achievement for Chicago Metal Rolled Products 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 Recently, a miscellaneous steel fabricator came to me with a very challenging project for circular stairs. They were looking to make a curved monumental staircase using 20 x 8 x 5/8 rectangular tubes. The stair was elliptical, had a reverse “S”shape curve at the bottom, and, of course, required helical spiral bending.
The curvature at . . . → Read More: Built Up Box Stair Stringers for Circular Stairs Roller/benders in the steel industry (those who specialize in curving steel) often work with miscellaneous and ornamental fabricators providing them with helical stair stringers to create circular stairs. Most often these circular staircases are rather large, suitable for a ballroom or spacious, multi-story atrium. Indeed they are called “monumental stairs.” The most common circular stairs, however, are much . . . → Read More: Circular Staircases Large and Small Steel section bending, whether it is curving angles, bars, beams, channels, tees, or other sections, most always requires extra material at the ends of the rolled material. This extra material goes by several names: “trim,” “waste,” “pick-up,” “tangent,” “grip,” “run-off,” and “lead in” and “lead out.” If the steel section is being curved on a three-roll bender . . . → Read More: Steel Section Bending: How Much Extra Material Is Required? |
