A practical two-day course to grade hardwood to the visual strength grades set out in BS 5756: 2007+A2:2017 'Visual strength grading of temperate hardwood. Specification'.

• An introduction to the natural growth characteristics of wood using handheld samples
• Practical exercises grading lengths of hardwood timber.

The course also includes:
