I was wondering if anyone knows the commercial name of this open web hybrid floor truss. The manufacturer is Weyerhauser (see photo) (now uploaded....sorry)
I am thinking it is a TJW Series (?). The joist is 18 inch deep.
This appears to be one of the "RedBuilt" open web trusses (joists) that may have been purchased from Weyerhaeuser. I've encountered these on a project before. You would probably benefit from contacting RedBuilt. When I contacted them once, they were actually able to locate the original account and provide me with the member design info.
Agree with JD, that's actually Weyerhaeuser 4-square wood, which was a branding of dimension lumber, rather than the Weyerhaeuser acting as the manufacturer of the truss. You can tell by the font style and horizontal line. Redbuilt would be the one to contact for this.
