STEEL C CHANNEL SIZES CALCULATOR

Steel C Channel Sizes Calculator for dimensions, moment of inertia, weight, and section properties of C channel. 

The designation of the steel channel gives information about the width and weight per unit length. For example C10 X 30 means 10 inches depth and 30 pounds per foot weight per unit length.

The dimensions of the American standard steel channels are defined in the annex of ASTM A 6/A 6M standard.
