Guess The Gauge

[jar546]

OK. Almost all of the metal framing for these non-loadbearing partition studs is 25 gauge the door frames, however, are thicker. Can you guess what gauge is being used around the door frames RO?

No clues via paint markings.

My guess, and it is purely a guess, is 18 ga (43 mil).

Why would you have a built up header for a 36" wide door opening? this is interior non load bearing correct?

Because the architect had a “typ” detail on the drawings.

I do not believe the code uses "gauge" to define thickness of metal products they use decimal or MM equivalents.

The IRC only refers to structural or load bearing walls.

R603.1.1 Applicability limits.
The provisions of this section shall control the construction of exterior cold-formed steel wall framing and interior load-bearing cold-formed steel wall framing for buildings........

No, but AISI does...

FWIW, ...I would also say 18 gauge !

Anybody can guess… Wendy guesses 50… because that’s two times 25. When told that she was supposed to guess correctly she correctly said that’s not what he said. She also wants to know if there is a prize. What should I tell her?
