16'8"x7'0" garage door lintel for masonry w/ 8 ft ceiling
16'8"x7'0" garage door lintel for masonry w/ 8 ft ceiling
(OP)
I have a small cmu residential structure w/ roof spanning 32' that will need to bear on a garage door lintel. No snow or seismic but high winds 129 ult. The lintel will need to span for a 16'8" garage door specified as 7'0" tall by designer. Since there is only enough room for one cmu course I don't think one prestressed/precast lintel serving as both bond beam and lintel could work?? I am interested in how others would typically detail this? precast? steel shape? concrete beam? limit garage door height? Thanks

Good find of seeing the detail that would have failed if it were made of wood. But, you've already spent more (of your time) addressing the issue than the tube steel is worth.
Your choices lay between a thicker wall (1/4, 3/16, 1/8, 11 gage, 14 gage for example) and a deeper section that may not need to be as wide: a thicker wall of course will let you use 6 or 4 inch TS deep for example, rather than 6 or 8 inch deep section.
Don't know what will be the best final choice -> much will depend on availability from your local steel shop. Getting something that short "from stock" will be cheaper than ordering a "perfect" piece from out-of-town.
Assume 6x1-1/2 tube steel, 14 g. To attach siding to the lintel, bolt a wood face to the side of the tube steel, then have your carpenters nail the siding/insulation/etc to the wood.
