Many Bender/Rollers not only curve metal in one plane; they also curve metal in two planes including helical coils. Applications in construction include stringers and handrails for circular stairs as well as ornamental and structural members for buildings.
On a smaller scale, Bender/Rollers make helical coils for OEM applications including for screw conveyors and augers. The ancient . . . → Read More: Helical Coils: Where’s Archimedes When You Need Him?
Curved steel companies may receive the same requests for quotations, but their actual products may not be of the same quality.
When purchasing straight steel, you largely know what to expect. There are standardized specifications and tolerances that steel mills have to meet in order to certify it. Straight steel is essentially a commodity.
Curved steel, however, is . . . → Read More: Making Circular Staircases: Quality Matters
Although on a smaller scale than the devastation caused by the recent tornadoes in Oklahoma, in Greensburg, Kansas, on May 4, 2007, a tornado destroyed the Big Well Museum and Gift Shop as well as the nearby water tower. No longer could visitors descend the stairway 109ft into the cavern of the world’s largest hand-dug well.

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
Some steel bending projects require the equipment and expertise from what might be called different disciplines within the bender/roller world.
A recent example involved a large beam stringer for a spiral staircase. It required W24x84 wide flange beams over 45′ long. Most stair stringers are made from small to medium sized channels, plates, or tubes that are . . . → Read More: Building a Stairway to Heaven – Utilizing Expertise from Two Processes to Create Stringers for Curved Stairs
Those working with steel often have requirments for custom parts that require multiple bends. Sometimes multiple machines are required to perform such a task. Using an experienced roller/bender with an extensive collection of rolling and bending machines can ensure accuracy and efficiency when bending steel.
A recent example occurred when a customer required custom brackets for pipe . . . → Read More: Performing Multiple Bends in One Steel Piece Across Multiple Machines
During this recession, we have repeatedly heard that because of the limited amount of work available, steel fabricators, whether structural or ornamental, are bidding on work they normally would not do. For one ornamental fabricator that meant fabricating a circular staircase for the first time.
Most fabricators turn to companies who specialize in curving steel to purchase . . . → Read More: A Miscellaneous and Ornamental Metal Fabricator Tackles a Circular Staircase
Bending pipe to a tight radius often requires the use of an internal mandrel to keep the round pipe from becoming oval, wrinkling or cracking during the bending process. Original equipment manufacturers (OEMs) usually do not have the expertise to do mandrel bending of pipe. Or they choose to subcontract this work because specialists can do . . . → Read More: Bending Pipe Into a Flat-Back U with an Internal Mandrel
What is the difference between a port cochere, a canopy, a portico, and a baldachino? Each one of these terms describes a structure that is usually subsidiary to the main building and that serves both an ornamental and practical function. The practical functions include protection from the weather; the ornamental functions include providing aesthetically pleasing architectural . . . → Read More: Functional Architectural Accents Using Curved (or Straight) Steel
