MSG (Machine Stress Grading) |

|
Although sawn timber can be purchased as "un-graded" or "run of mill"
or "non-structural", it is generally sold as a graded product. There
are several methods grading which predict the strength of the piece of
timber and each of those methods is set out in an Australian Standard.
Those methods include Visual stress grading, Machine proof stress grading and Mechanical stress grading. (See:
Sawn or Milled Timber)
Machine stress grading (MSG) is one system of mechanical stress grading. The MSG system provides a set of grades with specific properties. The grades are F4, F5, F7, F8, F11 and F14.
