Curved tubing is becoming increasingly popular in building design, and the introduction of a new grade of tubing may increase its usefulness.
As you know, HSS refers to hollow structural sections – round, square and rectangular. A new HSS specification, ASTM A1085, was announced at the North American Steel Construction Conference (NASCC) in St. Louis on April . . . → Read More: Curving a New Grade of Tubing: A1085
By definition, a job shop produces specialized products in relatively small batches, and this is true of companies who specialize in rolling steel sections. Such companies often develop a variety of customers who turn to these bender/rollers for their expertise in bending structural steel, steel plate and steel sheet.
One type of customer orders a “one-off,” that . . . → Read More: Rolling Steel Sections as a Job Shop and as a Contract Manufacturer
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. In a rotary shear process, materials are cut in the pinch between two overlapping hardened metal . . . → Read More: Rotary Channel Splitter
In the bender/roller industry a compound curve is comprised of bending a steel member across both it strong and weak axes, or as some may describe it, as being curved in both plan and elevation. This type of bend can be seen in some architectual entrance canopies on rather larger buildings or in this application as . . . → Read More: Bending Steel into Compound Curves
We have rolled and twisted the hard-way, helical flat bars known as strakes for use in preventing wind vortex shedding on towers, stacks and other tall round structures. The wind vortex shedding can cause damaging vibration in structures which the helical strakes dampen or eliminate.
Strakes can be attached to towers in multiple ways. Sometimes they are . . . → Read More: Clips to Attach Helical Strakes
In many cases, a company that specializes in bending structural steel to a specified radius is able to roll steel channels to create an “S” curve. The “S” shape can be formed either by curving two pieces of steel and then welding them together or by rolling one piece with reverse curves.
Rolling two pieces of steel to . . . → Read More: Rolling Channels into an “S” Curve with Straight Tangents
If one were to place bets on where you could easily observe curved steel sheet in its end use, the clothing section of a department store such as Macy’s or Dillards would probably be your last wager. If this were the case, you could end up in the hole some, as all you would have to . . . → Read More: Steel Sheet Curved into Cones for Attractive Clothing Displays
We recently had a unique job with unique packaging requirements. A customer was in need of helical strakes to wrap around a tower. Strakes are helical flat bars that are curved the “hard way,” i.e. against the strong axis. This is the same type of bending process that is used for ribbon mixers or ribbon flights.

Steel tees, especially larger tees, are produced by splitting a steel beam and then straightening or curving the two resultant tees to the required specifications. At times these specifications can require close tolerance work.
For example, WT12 x 27.5 steel tees were required to be rolled stem-out to an inside radius of 53ft 0.187in with 44ft 4in . . . → Read More: Creating Close Tolerance Curved Steel Tees
The requirement: Helically bending 5″ Schedule40 pipe with both variable pitch and variable radius.
The application: a sculpture commissioned for the FireKeepers Casino.
When FireKeepers Casino announced that they would add an onsite hotel, making their already luxurious gambling facility into a casino/hotel resort, they turned to Hotel|Casino|Resort design specialists, Thalden, Boyd & Emery Architects.
