Planning to attach pressure treated wood sleepers to a concrete patio and put deck boards over them.
I'm trying to decide on what fastener material is best to attach the sleepers to the concrete.
This is a wet exterior location. The concrete is bound to hold moisture pretty much all the time. (Using treated lumber means I have to use at least galvanized fasteners anyway.)
But I'm concerned that galvanized steel will rust out before the treated wood fails which would seem like a real waste. (Won't driving fasteners into concrete scratch off some of the coating?)
Is this concern unfounded? Will galvanized be OK or should I just go for stainless?
Stainless is more expensive. If its worth it, that's OK. But I don't want to waste $$$ either.
Note - I've not yet decided on what type of fastener - e.g., tapcons vs. wedge anchors vs. nail-set hammer drive anchors... etc.
