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 …

Formwork is the overarching term that’s used to describe the forming process. Shuttering is defined as the temporary moulds that are used to hold the wet concrete in place until the concrete has set and cured. Projects of different sizes will often …
