Deepest Beams Yet
Posted by Geoff Weisenberger on May 2, 2008 at 12:42 PM.

Nucor Corporation announced today that Nucor-Yamato Steel Company is introducing 44-in.-deep wide-flange structural shapes, becoming the first mill in the Western Hemisphere to produce sections to this depth.


Nucor-Yamato Steel Company, a joint venture between Nucor Corporation and Japan’s Yamato Kogyo Company, is introducing four 44-in.-deep sections: W44×335, W44×290, W44×262, and W44×230. The maximum length for these sections is 120 ft. The first production rolling of the W44 sections is scheduled for the week of May 25, 2008 and will be included in future rolling schedules.


These beams are of particular interest to the highway bridge market for use as “stringers” (primary bridge beams), horizontal load-carrying members that carry the bridge deck and roadway surface.


Until now, the deepest sections available from U.S. mills had been Nucor- Yamato’s W40×431 sections. The W40 sections and other deeper rolled beams have been seeing increased use in bridges, particularly in the Midwest.
