Looking for suggestions

I will soon be siding this house and I am not sure what to do with the awning supports. I built this awning over the doorway last year and just put up these angle supports made out of treated wood. I really don't want to cover all of that wood in aluminum the way it is now. I was thinking of reworking it so that only the diagonal piece is showing. I can use a joist hanger on the wood siding to support the bottom of the diagonal and that will be covered by the vinyl siding and J-channel. And, I could cut the horizontal piece into the trusses above and that would be covered by the soffit.
That would only leave the diagonal piece to be covered with aluminum.

What do you all think?

Thanks in advance!

Just a warning, the new PT will eat the aluminum.

I agree, any PT need to be weathered for a good month or so, thickly primed with something like Kilz exterior, then top coated with latex. Just to be safe you might want to prime the aluminum where it contacts the PT also with a metal primer.

Hehehehe...I sat here for a good 5 minutes trying to figure out what PT was!! OK, pressure treated...got it...duh, OK, I'm a little slow.
Anyway, there will be vinyl J-channel around it on the sidewall. The aluminum J and aluminum soffit of the eave is already there so I'll probably just leave it.
At this point I am thinking of just using a hanger on the wall for the diagonal and take out the 2x4 on the wall. There isn't much point in trying to notch the upper piece into the trusses since there wouldn't be much support left.
Also, I probably won't get around to trimming this until next year so the PT should be weathered by then and I'll prime it before covering it with aluminum.
I know they used to use chromated copper arsenate CCA but that was voluntarily phased out by the manufacturers. Not sure what they are using now. Will the new stuff harm the vinyl?

Thanks all!

PT of any sort is pretty nasty and corrosive. I don't know exactly what's used these days but I know that fasteners still carry warnings regarding "not for use in PT"; Stainless, hot dip galvanized and a few specialty coated deck screws are good for PT, rest aren't.

Don't THINK it would hurt vinyl but conceivably could stain it. Maybe buy it, leave it outside for a few weeks and throw a coat of Kilz on just the part that contacts the vinyl. That way the moisture isn't sealed in before its well weathered but the contact surface is protected.

It shouldn't bother plastics at all, its metal that its bad about. You need to check every hanger, nail and screw to see if its approved for use with the new PT lumber. Stainless and hot dipped galv are ok.

SS - Stainless Steel
PT - Pressure treat

Anyone who builds stuff and does drawings or specs learns to abreviate a lot.

Certainly won't damage plastics but could stain.

Have you thought of using Trex or one of the other composites.

The only experience I've had with the composites is when I used 2 spindles as part of my router table. I found that you must drill a proper size pilot hole for screws or the material will mushroom up and prevent a tight fit.
It is easy to work with and stays very straight.
I went through about a dozen pieces at the box store and did not find one that was what I considered croked. Can't say that for PT.
I'm not sure I'd use it on a deck floor but would probably use it to make the railings.
