For my ICF build Im using an engineered floor system and am looking for input on wood vs stamped steel webbs. Price seems to be very close so is there an advantage one way or the other? Many thanks P

When you're looking at wood, is it open web or I-joists? All systems have their +/-. If open webs are not a critical item, solid I-joists often have the best performance, all other things equal. But look at 2 major things. Not just load-carrying capacity, but deflection. When comparing two otherwise "equal" systems, look for the least deflection. Then if that's close, look at the joist weights. A heavier system will have the better vibration characteristics. (In general, and for residential.)
And for any span over 15 ft, code minimum is too much. Get the least you can afford.

Thanks Jerry Sound advice P

Jerry,
Please clarify. I assume you are referring to the deflection?

stamped webs are much lighter, more room for mechanicals and are trimable

Im trying to choose between the Posi Strut system and the OJ Triforce system. I wonder about the longevity of the wooden webs, I would assume they would dry out over time , suffer some dimensional shrinkage and be more prone to squeaks ? I haven't seen to many of the OSB I beam joists but i do recall that the knock outs for mechanical were seemed much more restrictive than the open web designs

Squeaks are more than often caused by a lack of glue or screw and not the type of floor system type.

You can get trimable wood web as well. If depth/span ratings were the same I would go with wood.

I would go with wood.

Why?

I ended up choosing wood ,Not based on strong feelings one way or the other but due to the fact that the wood was trimable and the steel was not .

peterswet;

The post was intended for greentree, but in any event you are mistaken. If you look at the photo of the steel web      'spacejoist "   floor truss they are trimable. Furthermore the all steel Dietrich Trade ready floor system and the Marinoware joistrite systems are also trimable.                        

Actually I'm not mistaken In the quote from the supplier it stipulated that the posi strut floor truss was fixed length and I would need to sign off on the measurement The posted photo was of a different brand

You better check again - Per Posistrut's website .......... "Posi-Strut is also available with an optional trimmable end, for even greater jobsite flexibility. And it's available when you need it!."

Ah , Available but not what I was quoted!

It is not unusual for suppliers to lack in product knowlege ................ just take a trip to the Home Depot

Chris,
Better spans with better deflection rating, less squash blocks, better strongback placement options.
One manu. you can verify this with is TrimJoist; basically same trimable design except wood webs.

Ok , Ive received preliminay drawings of the floor system and have been advised that "Rimboard" has been spec'd for the 4 end joists as it will be directly attached to the ICF
The Rimboard, (same stuff as timberstrand Im told) is only 1 1/8 thick,
My Simpson ICFCW hangers are obviously too wide as would be the ICFW
Would one shim this to fit or would a different hanger/ fastener be in order?

I'm late getting back in. I'm sure you'll be happy with wood. You'll find that there should be no inherent noise problem with wood, or their use of OSB.

Wes, Yes, poor phrasing of mine. code minim (deflection)is too much, and get the least (deflection) you can afford.
