US Patent:

58230424, Oct 20, 1998

Filed:

Mar 14, 1997

Appl. No.:

8/818476

Inventors:

Carl A. Snyder - McMurray PA
Michael A. Karczewski - Beaver Falls PA
Karl W. Shurskis - Hookstown PA
Sunil Saigal - Fairfax VA

Assignee:

J&L Structural, Inc. - Aliquippa PA

International Classification:

B21B 2300

US Classification:

723662

Abstract:

A method of forming and using a metal I-beam includes hot rolling an elongated metal workpiece to establish a web and a pair of flanges on the edges thereof. The web is formed with elongated reinforcement of solid cross-section having a generally straight longitudinal axis oriented generally parallel to the flanges. The hot rolled I-beam is cooled without forming substantial waves in the web and the I-beam is subsequently secured in a building construction or other structural product. The method involves the longitudinally oriented reinforcing means which preferably are one or more elongated laterally projecting ribs having such mass that the average temperature of the web prior to cooling will be sufficiently close to the average temperature of the flanges prior to cooling that the formation of waves within the web during cooling will be resisted. The reinforcement if preferably coextensive with the I-beam. The web is preferably substantially continuous.
