yah i know the kind...my son had some guys that built sheds that size one cost for building and to shingle it the whole bit ..cheaper those sheds and my gosh its still lasting...whenever it decides to call it quits he can just burn it...
i guess thats all these two guys did was go around and do that a father son team it seemed...got done in a day too...framing doors roofing etc...all he did after was slap a coat of paint on it.
surprising too because the materials were not the most expensive that its still lasting good...after 9 yrs.
Talked to a scapper guy and he said its about 10 - 12 cents per pound for steel but steel weighs more at the scales and he likes it better than aluminum because aluminum weighs (20 cents a pound)less and you need a lot to make anything.
ya know my son found a father son team who all they did was go around and build small wooden sheds approx the size of the steel or aluminum sheds...much cheaper ..i think it only cost him two hundred and that included shingles for it...that thing is still holding up just fine as he stained it also and its been ten years now...so it has more than earned its money and when it decides to finally go to rot ...its eco friendly
