Central IA | I found a 10 x 5 beam in my tables that would have the tapered flanges and weighs 17 lbs/ft. You could check the weight to see if it matches. At 20 ft out on a cantilever beam you wouldn't want more than 2000 lbs. Your post and floor anchoring would have to be checked. If the beam is supported on both ends, 4000 lbs in the center should be fine. It should yield at about 8000 lbs. Remember, check the weight. I'm not certified - if you want professional advise it wouldn't cost you much. | |
