Visual Strength Grading

Last week Tim attended a Visual Strength Grading – Hardwood course. The course was run by Exova and was a practical 3 day course to grade hardwoods.

Visual strength grading is the process of assessing timbers by reference to a grading standard which defines limiting characteristics that can be determined by visual inspection. These include knot size and position, fissures, distortion, wane, slope of grain, rot/insect damage plus a range of other abnormalities that can affect strength.

Tim passed his course so can now grade the timbers from Treelife's own sawmill for building projects.
