In conventional steel buildings mill-produced hot rolled sections (beams and columns) are used. The size of each member is selected on the basis of the maximum internal stress in the members. Since a hot rolled section has a constant depth, many parts of the member (represented by the hatched area), in areas of low internal stresses are in excess of design requirements.

Frames of pre-engineered buildings are made from an extensive inventory of standard steel plates stocked by the PEB manufacturer, PEB frames are normally tapered and often have flanges and webs of variable thicknesses & depth along the indidual members. The frame geomentry matches the shape of the internal stress (bending moment) diagram thus optimizing material usage and reducing the total weight of the structure.
