Yep, in the Navy that is referred to as "flame spray" and
is used to coat pipes and valves, especially steam lines,
makes them more corrosion resistant.
Also, if your boss yells at you really really bad, Navy slang is
something along the lines of "Yea, the C.O. took me out on
the starboard bridge wing and flame sprayed the hell out of me"

They'd probably spray the galvinizing on the frame ala metallizing which is
how they fix cranks in ships.
There's a place on Long Island which has the facilities to do likewise. They
build playground equipment and spray molten zinc on the completed apparatus.
They also do car frames.
