Selling these structural beams that were used for a double car shelter I tore down I didn't need in my driveway. They seem to be pretty strong but I don't know what they are rated for. The roof was 22 wide and 20 foot long made out of 2x4 that was pretty heavy so I guess they can hold a lot.. One beam is 19ft 9 inches and the other is 20ft 6 inches. They are both 12 inches wide. 200$ cash for both beams.
