I googled that to make sure what you were talking about (OSB I-Beam). Google gave me lots of links to builders who explained why TGI was far superior to 2x12. ;-) They forgot to mention cheap. The optional upgrade seems to be built up trusses, which I had been thinking about using for ease of use. A 28' would cost me about $70 though, making it more expensive than the roof trusses, and I'd need twice as many. > Use steel How big a floor I-Beam do you need to span 28'? And how far apart can you space them? Mitch.
