Hey everyone! I had some storm damage from Hurricane Helene that took out my old wooden shed, which was frankly a poorly built eyesore anyway. Now, I've got a new metal shed of the same size and I'm planning to remove the old one and put up the metal one on a concrete slab. My main question is how to securely anchor the metal shed to the slab. The shed's bottom plate is a galvanized steel beam with extensions for the wall studs. I was considering using some 2x6 pressure-treated wood between the slab and the bottom plate, but I'm wondering if there's a better way to do this.

You might want to drill and use split sleeve anchors. Since your bottom plate is galvanized, it should resist rust pretty well. If you're still worried about moisture, consider adding a half-inch thick barrier like vinyl, silicone, or some expansion joint foam beneath it.
Should I use the pressure-treated wood or just go straight to the slab?
