Just a quick question for anyone who has scrapped industrial roll-up doors. How much do they generally weigh? We had some pretty strong winds up here and one of the horse stables around here had three of their doors literally rip off of the walls and I may get to pick them up. They should be either 12 or 14 foot across. Any help on this would be greatly appreciated. Oh, and I did use Google and the search bar and all I could find was length and heights, not actual weights. Thanks!
