Exemplary embodiments include a structural system for replacing a standard beam. The standard beam has a weight per unit length, a depth in a load direction, a characteristic cross-sectional shape and a width in a cross direction substantially perpendicular to the load direction. The structural system includes a monolithic beam having the characteristic cross-sectional shape and the depth in the load direction. The monolithic beam may also have the weight per unit length. The monolithic beam includes first and second flanges connected by a transverse section. The first and second flanges extend in the cross direction and have first and second thicknesses, respectively, in the load direction. The flanges are not wider than the width in the cross direction. At least one of the flanges has the width in the cross direction. The thicknesses are different. The flanges and the transverse section are an integrated structure forming the monolithic beam.
