American standard beam (S Beam or Shape) dimensions, sizes and section properties.
American standard beam is generally known as S beam or S shape. S shape is a rolled section with two parallel flanges connected by a web. S shapes have relatively narrow flanges. The designation of the
S beam gives information about the width and weight per unit length. For example S12 X 50 means 12 inches depth and 50 pounds per foot weight per unit length.
The dimensions of the standard S beams are defined in the annex of ASTM A 6/A 6M standard.
