Architects, engineers and fabricators have asked whether tubing can be formed with both camber and sweep. The answer is yes.
An example of tube bending that induces both camber and sweep can be seen in the sinuous pedestrian bridge in Longview, Florida, shown below. 66 tons of 14in square tube with a wall thickness of 5/8in was curved . . . → Read More: Both Camber and Sweep in Tube Bending?
One of the most commons mistakes individuals make when ordering structural steel rings or steel sections is caused by the confusion of radius and diameter. When an individual is ordering the service of curving steel and has successfully communicated the orientation of the part (e.g. hard way or easy way), it is always wise to ask again, Is . . . → Read More: Bending Steel Sections: The “D” Word
A lintel can be a load-bearing building component, a decorative architectural element, or a combined ornamental structural item often found over portals, doors and windows. Often steel sections either straight or curved fulfill these functions. In fact, certain building codes, like Chicago’s, require that the lintels be steel sections.
An example where steel lintels are at once . . . → Read More: Steel Tube Bending for Lintels
Bending aluminum and steel sections to a given radius or diameter can contribute to “green” projects in many ways. For example, in Chicago a project for housing the homeless was going for LEED Certification. The design by internationally recognized architect, Helmut Jahn, called for wind turbines and solar panels that would generate 15% of the building’s . . . → Read More: Bending Aluminum and Steel Sections for Sustainability
A material take-off supplied by a Steel Fabricator to a subcontractor who specializes in curving steel yields quick and accurate curved steel quotes. What is a curved-steel, material take-off? The Steel Fabricator sends in a list of what they need curved and how. The information needed is basic: the piece mark; the quantity; the . . . → Read More: Curved Steel Sections? Material Take-Offs Yield Quick and Accurate Quotes
Recently a lady called Chicago Metal Rolled Products and asked if Bender worked here.
Here is a sketch of Bender creating a complex bend which includes (starting at the bottom of the beam and moving up) a compound bend which blends into a helical bend which blends into an easy way bend at the top with a . . . → Read More: Compound Bends by Futurama’s Bender
Some companies that specialize in rolling and bending metal for construction and/or for component parts for equipment strive for continual improvement in the curving process to yield improved curved metal products. These cutting-edge companies build on decades of experience that makes them a valuable resource for their customers.
Their customers, however, sometimes do not know exactly what . . . → Read More: Specifying Curved Steel Sections
In many ways, round metal duct work is more economical than rectangular metal duct work as a means of conveying air.
1) Size: For a given pressure loss, the surface area of rectangular duct can be double the comparable round duct surface area. Round duct, therefore, requires less metal than rectangular equivalents. Rectangular duct work often requires heavier gauges, . . . → Read More: Metal Duct Work: Round vs. Rectangular
We often receive orders for bending bars the hard way helically. While entering orders for such helical bending of stainless flat bar, I noticed that very often they have the same pitch—57.9 degrees. Helical bending of steel sections can be used for mixer blades, handrails on staircases, and auger conveyors.
But it turns out that this 57.9 . . . → Read More: Helical Bending of Bars for Strakes
