Identifying Open Web Steel Joist

Identifying Open Web Steel Joist

Identifying Open Web Steel Joist

(OP)
While trying to determine the size of open web steel joist supporting a roof I found a tag on the joist but it seams to be a fabrication tag. The tag states "18746J3 GUILLE". The joist measure 16" deep...most likely a 16K. Any tips on how to determine what 16 series the joist is? There are no as-builts.

THanks!

Call Guille Steel Products, Inc. at 804-497-3585.  Not sure they are still in business, but try it.  If they are in business they will probably give you more info than you need.

If not, call the Steel Joist Institute.  They might have a Guille Catalog.
 

RE: Identifying Open Web Steel Joist

If you go to the SJI website they have a online form to fill out and will tell you what size the joist appears to be. From my experience with them, they will get back to you the same day and are fairly accurate.

Put in a request at the SJI and its a 16J8. Where can I get data/load tables on this joist? THanks again.

RE: Identifying Open Web Steel Joist

dsr729...SJI sells a 50 year and older joist manual that has most of the catalogs. Good reference material for any structural engineer.  I have two different ones, but in storage so can't look it up for you.

RE: Identifying Open Web Steel Joist

Nhstrut and Ron are on point. You can ask SJI online, and my firm has the huge joist manual with like every joist of the last 100 years. Both are good resources.
