Canada, North America as a whole in fact, has the most involved systems for grading softwood of anywhere in the world – as well as the relatively ‘straightforward’ strength grading of commodity softwood lumber, done both visually and by machine, there are different grade requirements for a host of end uses, from laths to railroad ties, masts to muntins, and if a larger section with unacceptable knots can be cut up into smaller, knot-free, component size pieces, there is a grade for it!
