          Works as great magnet board for kids. It’s cost effective, easy to hang and magnets stick to it perfectly. Edges are sharp (as expected) so we built a boarder and put caulking all on the edges. We also framed in and hung other items on the wall (3D dinosaur frames and a felt board) but the galvanized steel is located on the bottom of the wall to the right side in the attached photo.

          Easy to use, cuts and bend with little effort. Worked well to add some extra cold air return ducting in my older home.

          I bought this Galv-Steel Flat Sheet to make a roof for our golf cart. It fit perfectly by miracle! I only had to trim a few centimeters on one corner due to my "square" fabrication skills and welding. After I was done mounting it with self tapping screws into the roll cage I reinforced it with rubber-in-a can on the top and plastic poster board underneath. I then covered all the edges with foam pipe insulation. It looks awesome, has withstood 40 mph wind gusts, and I've received many compliments. Master Flow rocks!

          Works great outside
          I used this for the top of my package box that is outside. Was easy to form around the frame and keeps the rain out of the inside.

            Used this flat sheet stock to create a door pan for an exterior door. It worked wonderfully. Easy to work with a hand seamer and folding tool. I've used in other applications to fix duct work and works great for that as well. Be careful of the edges as they can be sharp.
