Excerpt from Cambria Steel, 1901: A Handbook of Information Relating to Structural Steel Manufactured by the Cambria Steel Co Our Beams and Channels are made to conform to the American Standards, adopted January, 1896, in which the flanges have a uniform slope of one to six, and the dimensions, proportions and weights are determined by a regular schedule, as shown on the diagrams on pagel 22 and 28. The standard proportions of beams and channels are further shown on Plate 24. The principal structural angles now made are limited in number to conform to the American Standards, adopted December, 18m, and include eleven base, or a total of seventy-three, sizes for equal leg angles, and nine base, or a total of eighty-six, sizes of unequal leg angles, all varying in thickness by one-sixteenth inch, as shown on Plates 12 and 14 and tables herein. It is believed that these standard angles include a sufficient range of sizes to meet all usual structural require ments, but at the same time we will continue the manufacture of angles of special sizes and proportions for those who require them, as shown on Plates 18 and 15.
