Re: Lumber mill stamp; aka how to find out what I joist is installed

[Subject Prev][Subject Next][Thread Prev][Thread Next]
That stamp is just the lumber grade stamp Ior LVL info if it's LVL.  Not enough to tell)  It it's TrusJoist/ Weyerhaeuser, it'll say so on the web.  Probably Boise, too.  Are there any web marks at all?  Does it have perforations for knock-outs?  Web stiffeners?  Any other info like LVL flanges, plywood or OSB webs?

It looks like TrusJoist.

I've come across a job which has I joists on it which may be failing, but I'd like to know what I'm actually dealing with before I start crying wolf. Does anyone know if this stamp is from an I-joist mfr, and if so if it has any relevance in determining the joist grade.  If I can get a mfr, I can go from there if necessary (the contractor is cheap beyond all reason, so it's safe to assume the weakest grade made in this case).

Here's the stamp - it's the only marking I could find, and I could only find it on one of the 20+ joists. A little bird told me that this GC may have used Boise Cascade, but I can't find a matching stamp reference on their site.
