CONSOLIDATED STEEL CORPORATION 



In the following table this uniformity of quality is illustrated by results 

 taken at random from numerous tests of Bethlehem sections: 



Heretofore the largest beam rolled in this country has been '2 1 inches dn-p, 

 weighing 115 pounds per foot and having a section modulus of 246. \\ h<-ii 

 ever greater strength was required a riveted girder was necessary. Bethlehem 

 beams range to a maximum size of 30 inches deep, weighing 200 pounds per 

 foot and having a section modulus of 610, or nearly two and one-half times 

 the strength of the largest beam previously rolled. The opportunity for using 

 rolled beams instead of built-up riveted girders is, therefore, greatly increased. 



Bethlehem rolled beam and girder sections can be advantageously used 

 as girders for buildings, crane runways, short span bridges, track stringers, 

 and for many other purposes where the more expensive type of riveted girder 

 has heretofore been necessary, These rolled beams and rolled girders afford 

 a saving in weight of metal and also a large economy in cost of fabrication, 

 as they do not require the punching, assembling and riveting necessary for 

 building a riveted girder. Moreover, the rolled beams can be obtained promptly 

 as contrasted with the delay always experienced in procuring riveted girders. 



Wide flanges give increased lateral stiffness, which commends the use of 

 such beams in many cases, particularly as girders for bridge floors, where the 

 wide flanges afford ample bearing surface and rigidity. 



Three separate types of shapes are furnished : Bethlehem I-Beams, Girder 

 Beams, and H-Column Sections. 



BETHLEHEM I-BEAMS 



Bethlehem I-Beams from 8 inches to 24 inches in depth, inclusive, have 

 the same strength or section modulus and coefficient of strength as Standard 

 Beams of the same depth. Bethlehem Beams, due to the scientific proportions 

 of the sections, weigh generally 10 per cent less than Standard Beams of the 

 same depth and strength. For example, a Bethlehem 15-inch I-Beam, weigh- 

 ing 54 pounds per foot, has a coefficient of strength of 867,000. The correspond- 

 ing Standard Section is a 15-inch I-Beam weighing 60 pounds per foot, having 

 a coefficient of strength of 866,100. Therefore for equal strength the Bethlehem 

 Beam weighs 6 pounds per foot less than the Standard Beam, a sav ing of 

 10 per cent in weight.
