   An Fb value indicates design strength for those extreme fibers. The higher the Fb the stronger the wood. Lumber grade. A higher grade of a given species has a higher strength rating (Fb) and often has a higher stiffness value (E) too. Species of wood. All species are not created equal. For example southern pine is much stronger and stiffer than ...
