The size metal depends on what size was used to frame the wall initially.  The steel used by Dina was 2" so I used 1"x2" tubular steel to frame in the new windows before I covered the entire side with my sheet material.  I didn't go very heavy gauge steel because the framing is only holding the windows.

You need to know how thick your wall will be including the exterior fiberglass and the interior finish before you order the windows.  The interior flange that holds the window on is custom made to the thickness of your walls.  I know Motion (Penninsula) does this and I am pretty sure Stormtite does too.

I changed my interior material slightly and may have to put a thin rubber shim under the flange to get it pulled up tight now.
