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!
need to do a general internet search, someone has probably made a calculator for it or has a table of sizes/weights posted
I found a site that states 5lb/sq foot. That includes rails, brackets, spring assembly, door. ect.
So if the doors are 12' x 12' then the whole package would weigh 720 lbs. That sounds pretty accurate if they are steel doors.
HTH
I already have looked and all I find is sizes, but no weights. I have even checked ebayQuote:

That kind of what I was going to guess. I was thinking around 800 lbs.Quote:

I'm not too sure on the height though, but they are probably between 12-20 feet tall. I'm not too sure though, but I'm sure they weigh a heck of a lot. Thank goodness they have a tractor available!Quote:

They were fully extended when they were destroyed. What happened was they were fully extended to the ground when the winds blew on the outside side. They started rattling and shaking and broke some kind of rail or lock or something and then they blew up like a curtain would and started flapping. After flapping around for a little bit, they ripped off and flew across the horse arena. Thankfully there were no horses inside the arena. Anyway, I think they should be not under tension or there are no springs at all but only a gear box for the chain hoist system. It should be all steel (I'm crossing my fingers they may be aluminum but I'm not setting my expectations too high) so I can just toss it on my trailer and put them in the steel pile. That is is a perfect world, but with my luck they will be under pressure and be a pain in the a** to deal with. (Knock on wood!!!)Quote:

That would suck, but I have seen them before in person before they broke and they are diffidently metal. I just never thought I would be scrapping them!Quote:

They are approx 10' (had some 8' wood posts nearby and walked it out basically) wide and about 12' tall. They are made of tin for the most part, and some of the rail sections are made of extruded aluminum. Anyway, I emailed the maintenance manager and he wants to strip it for parts or potentially use the doors somewhere else. I honestly have no idea what is usable on them, but at least I have my foot in the door. I'm actually kind of glad they are 10' wide because that means that I can toss them on my trailer and strap down and go, rather than cutting them up and having to deal with the springs. Anyway, I here are some pics:

As you can see, the spring cover has been removed so they could remove the rest of the sheet metal that surrounded the spring. The main axle is bent and warped. All three are basically the same.

Pile of sheet metal from the doors. It's all galvanized tin so it will go as shred if I do end up getting the doors.
That top pic in your last post is what I was referring to earlier...the spring on that axle needs the tension released before it's unbolted from the wall or it will chase you off the ladder and around the bay till it slaps you around.
