We rebuilt a deck last summer and we would like to put up a sun sail to provide shade so the deck is usable during the day. Two corners will be mounted to the house, but at the outside corners of the deck I need 2, 3 1/2 or 4 inch heavy wall pipes in concrete to mount the sun sail. I plan on sinking them in the ground 4 feet and having 10 feet exposed. Anyone know where I can score two 14 foot sticks of heavy wall pipe for a good price?
