When thinking about whether if not welded steel is the way to go, think of it as an investment. Structural steel is relatively simple to pre-fabricate offsite, rather than building on site welding during the building process; this saves time and makes for a more efficient construction time. Also, metal studs have a lower R-Value. R-Value is the capacity of an insulating material to resist heat flow; the higher the R-value, the greater the insulating power. Lastly, fine thread screws will hold any material to a metal stud, but extra pressure needs to be applied because these are not self-tapping screws. Paradise Grills uses Welded steel which is 10x stronger and is easily movable.
