The following search interface gives you access to AISC's database of available structural steel shapes in the U.S. from major steel producers as well as which mills are producing the shapes.This availability is useful in the design process as a reference to determine the general availability of specific shapes. Generally, where many producers are listed, it is an indication that the particular shape is commonly available.
However, except for the larger shapes, when only one or two producers are listed, it is prudent to consider contacting a steel fabricator to determine availability.
