I may have an opportunity to salvage a large amount of corrugated roofing from chicken houses. It's corrugated steel, and I suppose galvanized. I'm guessing it's about 26ga. Has anyone scrapped galvanized sheet metal? Do the yard pay less for it? More? And can anyone tell me what is the most common metal gauge used for this application? I'm guessing at the 26ga, but it might be heavier.
Thanks.
