| Pole barn....
I was not sure if this was the right place to post.Please move if necessary.
I am building a pole/pipe; barn/shed.
Fixing to build trusts' out of 2 3/8 oil field pipe.
If width (outside wall to outside wall) is 30 feet and I want a 5/12 pitch on roof; how much rise in center ( at crown) should I have?
thanks |
