LLNOS STEEL COMPANY NTRODUCTORY During the past few years there has been a demand, from Engineers, Architects, and other users of structural material, for lighter "" Beam Sections than the present American Standard Minimum Sections. This demand 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 was not required by the specified loading. n order to take care of this demand, we have developed a series of Special Light Structural Beams which we are now prepared to roll for the trade. n developing these sections we have slightly departed from the range in depth of the American Standard "" Beam Sections, in that we have introduced a Beam 2 inches in depth. This was done to make the range in the depth of the beams in the Light Beam Series more uniform than in the American Standard Beam Series. The dimensions and the properties of these beams are shown on the following pages. For convenience in designing, we have also added tables showing the properties and carrying capacities of the American Standard "" Beams rolled by us.
