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 “F14”, which indicates that the timber’s working stress in bending is approximately 14 MPA (Megapascals). The timber stress …

Timber Grading – Strength Do you know how strong your timber is? A timber’s strength in a construction context refers to the ability of a piece of timber to maintain stress (force) without ‘failure’. ‘Failure’ in this sense doesn’t necessarily mean breaking, but is more about bending strength, ie: how much downward force can be applied without the member deflecting …
