   Walls and roofs, no.

   Floor platforms, yes...with TJIs.

   Around here, probably 90%+ of the wood webbed floor trusses are set 19.2" O.C.

   I-joists are almost always done on 16" centers. Probably 99.9% of roof trusses are set on 2' centers.

   .

   I did a hip roof job a few years back that was 19.2" O.C. He couldn't bring himself to set the truses 2" O.C. and use 7/16 OSB ply on the roof. And he was too cheap to pay for trusses 16" O.C. or use thicker ply on the roof. He was a real moron.

   But I think that's the only roof job I've ever done at 19.2" O.C.

   Infamouse? Is that some poor relative of Mickey Mouse?

   I've seen pictures of webbed floor trusses, but they don't use 'em in these parts to my knowledge. Always looked like a good product to me.

   Almost anything I design new has the open web floor trusses.

   The subs love me.

   My own house has TJIs @ 19.2 for the first floor and 4x9s @ 19.2 for the upper floor, and full rough 2x8s @ 19.2 for the roof framing

   I've built a number of things with 19.2 centers, but always floor systems and never roofs or walls.  I find them to be handy.  More room between when doing plumbing and wiring later, but without having to go to 24" centers.  House I'm building now has 19.2 centers with 16" high IPI joists.

   The open 2x webbed floor trusses are even easier to run pipes and wires through, but they cost more than the OSB type floor joists.Something is what it does.

   Been framing floors and roofs with TJIs here in Western Washington for years that way.  A guy who used to build houses here and has since moved to Vegas to build was the first one to show me walls on 19.2 - that was 10, maybe 12 years ago. 

   It's probably more common than you think.  Just not something a lot of folks talk a lot about except with other open minded pros.  I can see how other folks would scoff and say derisive things about it - and that's never good for the reputation.

   Did some steel studs in NC on 19.2..that's all. I just never think of it as an option..old habits die hard.

   Yeah, I've seen it done for floors, using wood I-beam joists.

   Funny you should mention it. I had framed a 14x32 deck at that layout the dayu before that thread came up. The surface will be Ipe` which they claim spans 24" just fine, but the most effiecient I could do with the 2x10s for the load was at 19.2"OC
