Re: TJ50 joists

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Coming into this late: I always thought that TJ joists were manufactured by Weyerhauser. But the old joists have wood flanges and bent tubes for webs and are called open web joists.

Check out this web site

You can probably contact this company as they apparently are the original inventor's of the system.

I downloaded their spec and there's no nomenclature for TJ150 joists - but you can probably call them Monday 1 888 859-6757 and someone there may be able to help you. I know I have the old catalog some place but haven't been able to locate it yet.

I have a 1970 (?) school that has a mezzanine framed with 22 inch deep
TJ50 joists at 24" oc. The joists span 20 feet. Does anyone have a load table for this joist? TIA.
