Raising a threshold
Is there any reason I shouldn't put a PT 1x6 under the threshold of a new swing door in a concrete-floored garage? Other than the obvious trip-hazard? The idea is to raise the lightly-primed wood frame of the new steel door above water that tends to end up there after storms.

You "can" do it, just make sure there is support under the lip edge of the threshold. Silicone it to the concrete and silicone the threshold to it for a good leak stoppage. You may want to consider 5/4 x 6 since it has a radiused edge and may look better if it were left proud of the end of the metal threshold. It may take two, one split, depending on the overall width of the threshold.

I was thinking of a cellular PVC trim board but I was wondering if it would compress or collapse. I've seen some in the stores with dents. Composite deck planks are too thick.
I like the look of the 5/4 decking planks because of the radius, and that's what I was considering. Treated with a CPES product like Rot Doctor, then painted.

Well, if 5/4 is ok height wise..why not something like Veranda. I know the Veranda that HD sells is the same size as regular 5/4 decking. I've used it just like you plan, as well as for the trim under the door and in areas that will get a ton of weather and be a PITA to paint or access after install.
No rot, no compression, no maintenance.

As far as I'm concerned, everything touching bottom should ideally be either plastic, aluminum, or concrete! So I would prefer a rot-free alternative.
I'll look for Veranda. The stuff I saw had 3 deep molded ridges running lengthwise along the bottom (presumably for stiffness) and was much thicker than 1 inch - more like 1-1/2 - if you include the ridges.
Does everyone agree that vinyl/pvc trim board would not fare well if I had to drag something heavy over the threshold?
What the heck does 5/4 mean anyway?

The vinyl trim that I've seen and used will mar up pretty bad. Its not really designed for use in areas that will see a lot of abuse or contact. Dents, dings, scuffs etc would be a problem in this application I would think.
As to the 5/4 thing...I believe its the size of the wood before final milling, so 1 1/4" after milling becomes 1". Sorta like how a 2x4...isn't really.
And I may be wrong about the Veranda name...its the composite decking with a woodgrain on one side and a smoother non-slip pattern on the other. It may be called TREX...but I swear what I bought here in AZ was labeled Veranda. I guess it may depend on the region.

No you were right - Veranda. I was looking at Lowe's - it's the same thickness as wood 5/4 and thinner than the Lowes brand of the same kind of thing.
It will work perfectly. Less $$ than PVC too. Thanks for the suggestion!
