Q:You specs say this product is 1/4 inch thick. You state is as .25 inches. There is no way it is .25 inches thick. Not if it is 30 gage. Lol

great for duct repair
Just installed a replacement split heating and cooling system and needed to repair a section of the ducting, the Master Flow galvanized steel flat sheet worked great for this. The sheet was easy to work with and being galvanized will help prevent rust.

Exactly what I ordered & worked for my project perfectly.
This is mounted to the wall & I made a frame around it & this is across from the refrigerator. No more cluttered refrigerator.
A relative wanted one so I bought another 24X36 sheet medal & put it in a picture frame & hung it on the wall near refrigerator.

As our family expanded, so did our need for large surfaces where we could display the grandchildren's artwork and swap out the family photos as they grow. We chose the hallway, priced memo boards, but then opted to construct our own 9' panel using three of the 24x36 galvanized steel sheets after we bound the edges with silver duct tape. We then screwed them directly into the wall and painted a simple border. We considered covering the panels in a lightweight fabric with spray adhesive but decided we preferred the rustic metal instead. (For those who don't care for the shine, there are web tutorials for "aging" the surface).The magnets hold easily but the refrigerator magnets are less obvious and have a stronger pull for items such as greeting cards. Our formerly plain hall has become our own personal mini art gallery!

The product is very easy to work with. Cuts and Drills without a problem. The reason I bought this item was to stop a Red Squirrel from making a home in my 10' x 10' shed. The flooring is Marine Grade Plywood and over many years has lost its hardness. Mr Red Squirrel had found a way into the shed by chewing a hole in the wood a foot or so from the edge perimeter last year. He brought in hundreds of Nuts to have for the Winter. Upon opening the shed this Spring what I found was not pretty. Now What. The solution was to install a Steel Floor. The Master Flow Steel Sheet was the answer. Installed the steel floor in May and have no issues with Mr Red Squirrel returning to the shed. Great Product.

I bought 3 of these to use as magnetic chalkboards in my kids' playroom. I primed and did two coats of chalkboard paint. I lightly sanded the metal before priming, but didn't bother to sand between coats. They've got a few rough spots in them, but they're for the kids and they really don't notice those sort of things.
We've been able to stick a bunch of learning magnets to them (letters/shapes/numbers) and the kids have had a lot of fun using them. It dusts well with a microfiber towel and I wipe them down at night with a damp towel with no issues.
They do have a sharp edge to them, but we framed them out to prevent that from being an issue.

easy to fabricate
Very manageable. I used to fabricate a spacer between new furnace filter and existing ductwork. Did not have a bender, but it is easy to work with it - it's not too thick.
