6 LLNOS STEEL COMPANY n trod uctory n response to a demand from Engineers, Architects and others interested in Structural Material, llinois Steel Company developed and has furnished for several years a series of "" Beam Sections lighter than the present American Standard Minimum Sections. The demand for these Light Beams was caused by a desire to bring about better economy in the designing of buildings and other structural work where the depth and rigidity of the American Standard Beams were desired, but where their full strength wr..s not required by the specified loading. n developing these sections, we departed slightly from the range in depth of the American Standard "" Beam Sections and included a beam 2 inches in depth. This was done to make the range in depth in the Light Beam Series more uniform than in the American Standard Beam Series. The dimensions and properties of the Light Beam Series are shown on the following pages, and for convenience, we have also included tables showing the properties and carrying capacities of the American Standard "" Beams rolled by us.
