CONSOLIDATED STEEL CORPORATION 



All Bethlehem sections are of open hearth steel exclusively, conforming to 

 Manufacturers' Standard Specifications and also to American Railway Engi- 

 neering and Maintenance of Way Association Specifications. Material comply- 

 ing with any other standard specifications may be furnished by special arrange- 

 ment. Large ingots, up to 10 tons in weight, are used, so that the work of 

 reduction in rolling the shapes is sufficient to develop proper ductility of metal. 



EXPLANATORY NOTES 



The flanges of Bethlehem 1-Beams and Girder Beams have a uniform slope 

 of 9 per cent. The flanges of the H-Column Sections have a uniform slope of 

 2 per cent. 



Bethlehem I-Beams and Girder Beams are increased, as shown in Fig. 1. 

 by spreading the main rolls, which adds an equal amount to the thickness of 

 the web and to the width of the flanges, all other dimension-; remaining un- 

 changed. 



H-Column Sections are increased, as shown in Fig. 2, by spreading both 

 sets of rolls; the thickness of the web and the width of the flanges arc in< -rva^ -d 

 equally, the thickness of the flanges being increased a proportionate amount. 



Weights tabulated for Bethlehem I-Beams provide sufficient variations 

 for ordinary purposes. Only the minimum weights are tabulated for the 

 Girder Beams. Intermediate or hea\ ier \\ eights, corresponding to the usual 

 variations of Standard Beams, may be furnished by special arrangement. 

 The H-Column sections are rolled only to the weights given in the tables. 



The sections are numbered throughout the tables for convenience in identi- 

 fication and ordering. 



Shapes will be cut to ordered length within an allowable variation either 

 way, as follows: Bethlehem I-Beams from 8 inches to '2 1 inches inclusiv e, with- 

 in % inch; all other sections, within % inch. For cutting with less \ ariation, 

 or to exact length, an extra price is charged. 



Sections are rolled to catalog weight but may have an allowable variation 

 of 2 1/2 per cent from nominal section.

 to 23 inclusive are given in pounds per lineal foot and kilograms |>T
