BETHLEHEM STEEL COMPANY. 



Bethlehem I Beams. No changes have been made in 

 Bethlehem I Beam sections, and the list of sizes is the same 

 as previously, except that the three new I beam sections, 

 recently added, viz.: B18 a, B22 and B24 b, are included. 

 These three new beam sections are increased by the same 

 method as explained for Bethlehem Girder Beams, and their 

 flanges have the same bevel of 8f per cent, or a slope of 

 1 in 12. 



All other Bethlehem I 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 dimensions remaining unchanged. The 

 bevel of the flanges is 9 per cent. 



Bethlehem Columns. Four new weights have been 

 added to the series of 12" H Columns, and two new weights 

 to the series of 10" H Columns. Tables are given of prop- 

 erties of 14" H Columns reinforced with cover plates, when 

 columns are required of greater sectional area than the 

 largest 14" H Column rolled. 



All Supplementary Column Sections, which were recently 

 added, are given in this catalogue. 



Bethlehem 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 are increased equally, the 

 thickness of the flanges being ? increased a proportionate 

 amount. 



Flanges of all column sections have a slope of 2 per cent.
