I constructed a header for a 16' overhead door opening on the garage I
built. The sidewall containing the open was load-bearing for a truss
roof. I laminated a ¼" ~17'x9" steel flitch plate between the 2x10's
and bolted the whole thing together with carriage bolts as he proposes
(staggered). The garage is now 20 years old and there is absolutely NO
sag in that header - none. It'll take a fire to make that puppy sag.
Overbuilt? I dunno. That's what the plans called for in the header.

IIRC correctly the ¼" steel flitch plate w/bolts may have been an
alternative to either ½" or 3/4" ply nailed.

BX1's best bet is to check with Building/Zoning or Community Development
in his town and see what they say. To overbuild is never a crimeg

I'm working on a garage design. For a span greater than 9 feet, our local
code requires two 2x12s sandwiched around a 1/8" steel flitch plate. I'm
curious where one would obtain a 17-18' long steel plate 11.25" wide.
