Curved Structural Steel and Curved Steel Sheet Beautify Transportation Routes

What can a community or chamber of commerce do to beautify a viaduct when it runs under a railroad line?  Not much.  The crumbling faces can rarely be modified because they are owned by the railroad.  Don’t even think about anchoring nicely finished panels to the scummy inside walls…those also belong to the railroad.  The newest . . . → Read More: Curved Structural Steel and Curved Steel Sheet Beautify Transportation Routes

Fabricating Box Plate Stringers for Circular Stairs

Steel circular stairs (sometimes called “spiral stairs”) commonly incorporate “stringers,” structural members that support the treads, side walls (if any), and handrails.  These stair stringers can be made of plate, channel, beam and tube (round, square and rectangular).  These steel sections are most often curved into a helix but are sometimes formed into more complex compound . . . → Read More: Fabricating Box Plate Stringers for Circular Stairs

Saving Money While Creating Reverse Curves in Structural Steel

As architects and engineers continue to push forward with ever more challenging designs for steel structures, companies that supply the service of curving steel have responded well to the new demands.

Increasingly, designers are weighing the costs and benefits of various proposals.  In the best case, benders and rollers (companies that specialize in curving structural steel) are . . . → Read More: Saving Money While Creating Reverse Curves in Structural Steel

Helical Coils: Where’s Archimedes When You Need Him?

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?

Making Circular Staircases: Quality Matters

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

A Spiral Staircase for the Largest Hand-Dug Well

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.

Bending Steel into Compound Curves

In the bender/roller industry a compound curve is comprised of bending a steel member across both its 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

Clips to Attach Helical Strakes

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

Building a Stairway to Heaven – Utilizing Expertise from Two Processes to Create Stringers for Curved Stairs

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

Performing Multiple Bends in One Steel Piece Across Multiple Machines

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
