How much money would i get if i sold aluminum scrap metal for recycling?

Depends on what they're paying per ton and how much the doors weigh, since they're screen doors, probably weighing about 4 lbs a piece, I'm going to say like a dollar and a half.

To quote an old saying "if it sounds too good to be true, it probably is." Clean aluminum is bringing a pretty good price from the scrap metal dealers but painted aluminum like your siding is only worth about 1/3 as much as clean. If you want to improve the appearance of your house your most inexpensive option is to paint your aluminum siding.

How many pounds is a standard aluminum screen storm door without the glass?

currently that type of aluminum scrap is around .41 cents per lb which varies across the globe depending on your locations.

you will make as much as the cost of the gas to get you to the scrap yard.

About 5 bucks. It really about the weight.

It depends on the recycle center. go to www.earth911.org to find a local center and call for their rates.
