Structural beam bending, more specifically camber, was required to help support the 24 floors added to the original 33-story tower. The structural steel fabricator came to Chicago Metal Rolled Products for help on this vertical integration, a rather unusual form of building.
The project called for a variety of beam sizes to be bent the . . . → Read More: Structural Beam Bending for the Addition to the Blue Cross/Blue Shield Building in Chicago
Mitsubishi Heavy Industries needed 750 tons of curved steel rail to support the retractable roof at Miller Park, home to the Milwaukee Brewers, 2011 National League Central Champions.
The required profile bending called for 2100ft of heavy rail to be rolled to a 600 ft. radius with a tolerance of +/-1/4in. The steel sections are . . . → Read More: Profile Bending for the Retractable Roof of Miller Park
With the St. Louis Cardinals hosting Game 1 of the World Series tonight, those in steel might be interested to learn that the bending of pipes for Busch Stadium was designed to pay tribute to nearby Eads Bridge, the first major bridge utilizing true steel.
Completed in 1874, the Eads Bridge was the longest arch . . . → Read More: Bending Pipe for the St. Louis Cardinals Busch Stadium
The beautiful staircase below was made more attractive by incorporating profile bending to create helical handrails.
The profiles are comprised of ½ x 2-1/2in flat bar (top rail) and traditional handrail moulding (bottom rail) both rolled the hard way to a 5ft 2-1/2in and 5ft 6in inside radii respectively into a helical shape with a . . . → Read More: Profile Bending for Helical Handrails
Most rolled angle rings (also called angle flanges, companion angle rings, standard angle rings or blow pipe rings) are rolled leg out (i.e. they look like an old-timey, straw hat without the top) and are made from equal-leg angles (e.g. 1/2 x 1/2 x 3/8in).
Leg-out angle ring (left). Leg-in angle ring (right).

An interesting request involving rolled angle rings came our way recently. Occasionally for OEM and other customers, parts are needed where it makes sense to have additional work completed outside of bending and rolling before it is received by the customer. Some advantages could include freight savings, reduction in lead time, and reducing paperwork/workload.
Recently an OEM . . . → Read More: Powder Coating Carbon Steel Rolled Angle Rings
The bending of pipes and tubes can contribute to the aesthetic value of a project. For example, currently under construction, the Skokie Oakton Station is already exhibiting its “beautiful canopy of architectural steel arches” according to the Swift Updates Newsletter. “The Village of Skokie and project partners are pleased with the progress thus far . . . → Read More: Multi-Radius Bending of Pipes for the CTA Yellow Line, Oakton Station, Skokie
Steel plate rolling is often required in the nuclear industry, for example, to enclose a spent nuclear reactor.
In one instance, 2in thick steel A36 plate 58-1/2in long was rolled into full cylinders with a 128in outside diameter. The plates were plasma trimmed with a single longitudinal V-groove bevel of 30 degrees and a 1/8in landing. Some . . . → Read More: Steel Plate Rolling to Enclose a Spent Nuclear Reactor
