The strength of Australian timber is described in terms of "stress grades". Stress Grading is a way of classifying timber, either visually or by mechanical means to indicate the basic properties to be used for structural design purposes. The stress grade is designated in a form such as "F17", which indicates the relative bending capacity of timber.
