Depends on what it is protecting.
What is it protecting exactly.
I don't know.
I've never seen it. Could be:
- drip edge metal over the edge of the slab with the sill plate on it, with the siding covering the drip edge, with the drip edge acting as a flashing (except that drip edge face looks to be full face and not covered much, if any)
- drip edge metal over the sill plate with the studs nailed through it to the sill plate, trying to serve as a flashing over the sill plate
- flat brake metal with the turned out edge installed vertically behind the siding and hanging down to act as a flashing over the sill plate/slab joint
Regardless, if any of the above, or for any purpose like the above, any flashing which is rusted out needs to be replaced. I can't imagine someone going to that effort without it having been a requirement.
That said, many areas do not allow galvanized flashings near the ocean, only copper or stainless steel, in which case, this flashing should have been one of those???
