Concealed or through-fastened

If I were to flip this panel over, this has a quarter inch reveal. Okay, this is stainless as well. But this panel with this offset joint is typically used for a fastening back to a steel frame. I would not use this panel typically for a partition inside a plant or a plant ceiling,

because I like the 45 series stackable joint. You could flip either side of the panel over and it could be a finish. Whereas this, you're married to that offset joint if you're going into a steel frame, obviously. And they also call this a concealed fastened joint. The KS45 is what they call a through fastened joint. So you'd have to secure that panel if you were tying into a building, say, in excess of, for an interior partition wall, it's in excess of 30 foot. You'd have to have an intermediate girt, so you'd have to fasten through the face of a 45 series panel. Whereas then you might decide you don't want that screw shown. You're going to go with the 42 series panel. That's a concealed fastened panel.
