<p class="MsoNormal">We are looking at a roof mounted PV system on a building with light gauge steel roof frame. Only attachment that looks to be compatible out of the box is the EcoFastenSolar Quickfoot because it uses OMG XHD screws which are intended for
such an application. We have used this before and are comfortable with it, but anyone have any other products they have used successfully? I know no one here wants to give professional engineering advice (and I would not take it as such) but does anyone
have any success stories or things to look out for? Thanks,<u></u><u></u></p>
