Quality Control in Truss manufacturing
Timber Truss Housing Systems, Inc. maintains a rigorous quality control program. We have our own in-house TTHS Quality Assurance Program. Lumber is stored in covered lumber sheds and monitored for moisture content to assure no trusses are manufactured with wet lumber. A quality control checklist is followed for every setup. All truss types are inspected to assure they are properly jigged within allowable manufacturing tolerances. Proper lumber sizes and grades are checked. Plate size and placement is checked for every setup. Finally, the trusses are checked to assure the plates are properly pressed.
In addition to the checklist followed by the assembly crew, we have an in-house quality control inspector. He inspects trusses in progress and inspects finished trusses waiting to be shipped. His job is to perform a more stringent inspection. He double checks the geometry of the truss to assure accuracy. He overlays the connector plates with a template to assure they are properly placed. Each joint is visually inspected to verify tight fitting members and fully imbedded plates.
The final step of our QC program is participation in the WTCA (Wood Truss Council of America) in plant QC program. We are third party inspected by WTCA approved inspectors. These inspectors are employed by TPI (the Truss Plate Institute). They verify our lumber is properly stored and grade marked. They verify the lumber comes from an accredited mill. They inspect our connector plate supplies to assure they are the correct gauge and are properly marked. The third party inspector inspects jobs both in progress and finished. He also verifies proper truss geometry, lumber size and grade, and correct usage of connector plates. Finally, he verifies the trusses are properly banded and stored prior to shipping.
