Grade Stamp Not Recognized by National Building Code
The grade stamp shown below was recently observed in Quebec.
This grade stamp is from a CLSAB Accredited Agency; however, the grade stamp is not valid for structural use in Canada as:
- the National Building Code of Canada has no recognized design values for SPF-S lumber, and
- it does not contain a grading rule approved by the CLSAB such as the NLGA.
Questions about this matter can be directed to Chuck Dentelbeck, President & CEO, Canadian Building Associations and Officials: firstname.lastname@example.org.
