M-D Building Products 57042 2 3-Feet .020-Inch Thick Cloverleaf Aluminum Sheet, Silver

I'm a theatrical lighting technician and bought this item to make a tiled floor pattern for an Indian palace. Worked perfectly for that show. Not sure how many uses I'll get out of it but it saved me (and my client) a ton of money for this show.

I used that to swap out my ugly air vents and it looks awesome.

Used this to replace the wooden panel with a decorative look.

Bubble wrapped very nicely, then put in a box nearly twice its size, so it bounced around inside, giving it warped corners and edges. Luckily, I wasn't needing it for a "delicate" project and made it work.

Worked well for the screen door to keep the dogs from going through it. I used # 8 1/2 metal screws and they were short enough not to go through to the other side.
