Building a patio cover with exposed beam framing, need some advice
I'm in the process of building a gable roof over my patio. My plan is a 5/12 pitch with exposed 4x6 rafters placed about 22 oc because it lays out best that way. Rafter length is about 14 feet.
I need LVL's for the load bearing sides and I want that exposed. The load bearing sides are about 15' long with one side having a center support and the other being an unsupported span of 15'. My thought was a double 1-3/4 x 11.75" LVL on the unsupported side with a spacer and a 2x12 to make 5.5" which is my post size. On the side with a center support I'd go single 1-3/4 x 11.75 and build a spacer wall to fill the full 5.5". Across the front gable end, the span is 23' with a center support. My plan is a single LVL 1-3/4 x 11.75".
My problem is, as I said above, I want the beams to be exposed and I can't seem to find anyone that carries a treated LVL. I'm also debating if I want my 4x6's to be treated even though they'll have 1" stained tongue and groove carsiding on top of the exposed rafters and then on top of that 2x4's to attach metal roofing. the Space between the metal roofing and the carsiding will also act as my wire chase for lights and a fan.
Okay builders, LMK what to do! I'll post a pic of the project later.
