Space Joists
(OP)
I am interested in this product known as a space joist....wood flanges, metal webs for some development work (one project is commericial, the other multi family duplex)
Like these: www.spacejoist.com
Has anyone used these? The first question my clients are asking is how much more it costs than conventional wood I joists.
Field modifications seem impractical. The manufacturer says they come with trimmable ends.
Any experience with this type of product would be appreciated.

RE: Space Joists
Looks to be a well thought out product integrating the best of both products. I would be interested in seeing a cost comparison with the other joist types for the same spans, and if these are available on the West coast.

I like that concept very much, but their website is so sleazy, that now I have suspicions about the product and the company backing it.
The bottom line is cost, and chances are, they are the most expensive option short of going to all-steel.
The definition of a structural engineer: overdesign by a factor of 1.999, instead of the usual 2.

They only seem to work well in open floor plans.

Open web has obvious pass through benefits compared to solid web,
The iJoist style end makes it field trimmable which captures a significant advantage of an iJoist and eliminates the too-particular fitting issues of some of the open web joists.
I personally like the web to chord connection as I prefer the many nails of the press-plate to the single bolt or pin of so,eyeing like the trus joist products, although the pin is elegant, I kinda like not removing wood material for bolt holes especially on tension chords.
I know nothing about costs, manufactured quality, engineering values etcetera, code acceptance.

They need to list the ICC reports, and most of all, give design info - load tables, the usual stuff.
Otherwise I never take any product seriously, and this website is horribly designed.
