Re: [RE-wrenches] PV On Corrugated Metal Roof on Steel Building

[Allan Sindelar]

Jason, We have installed to similar buildings using #14 tek screws. If you look into their rated pullout strength, you'll find that the large gauges have surprising pullout resistance in purlins. And no interior scaffolding is required.

The corrugated metal is not a problem – we have solutions for that. I am wondering about how to best attach to the structural members.   For an idea of what we are up against, see: http://www.fafcosolar.com/download/349/IMG_0828.JPG   Any suggestions for attachment methods?   Jason Szumlanski Fafco Solar   _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
