Truss Plant Qualification

To accomplish its purpose, the WWTABC provides a comprehensive
Truss Plant Qualification Program for its members. The Program is the
product of years of accumulated knowledge of many individuals within the industry.

There are two major components of this program:

• internal in-plant quality inspections and,
• external quality audits

One of the conditions of qualification is that plants subscribe to regular unannounced
quality audits to verify the ongoing quality of lumber, plating, and overall manufacturing
details of trusses. It serves as a means for plants to demonstrate compliance with the
following Minimum Quality Manufacturing Criteria:

• Truss Design Procedures and Specifications for Light Metal Plate Connected Wood Trusses, Appendix G, Minimum Quality Manufacturing Criteria.
• The above Standard is referenced in the BC Building Code, Article 9.23.13.11 Roof Trusses.
