The Assurance of Quality
Quality is no small matter. When it comes to the manufacturing of wood trusses quality means more than just ensuring that the design of the trusses meet the building code requirements. In order to belong to the Western Wood Truss Association of Alberta member Truss Fabricators must meet the requirements of the WWTA including:
Management commitment to quality
Agreement to abide by the WWTA Code of Practices
Design drawing requirements
Lumber handling and storing requirements
Continuous inspections of metal plate placements
Continuous inspections of truss dimensions
A process of continuously improving quality
Pass the WWTA quality assurance audit
Only Truss Fabricators that meet the Western Wood Truss Association of Alberta Quality Assurance Criteria are issued a stamp like the one above.
So to ensure that the trusses you are purchasing or inspecting are coming from a fabricator that has a commitment to quality look for the stamp.
For a list of Truss Fabricators that are currently members of the Western Wood Truss Association in good standing refer to the members list on the home page.
All members of the WWTA are issued a stamp with their plant number on it so if you have any questions about your new or old trusses please call the WWTA at (403) 279-3385
DO NOT attempt to alter or repair trusses without first consulting an engineer.
