Rated 4.3 out of 5 by 10 reviewers.
Rated 4.0 out of 5.0 by Purchase The sheet of galvanized steel worked perfectly as a magnetic whiteboard. Fairly easy to cut and looks great. August 13, 2014
Rated 5.0 out of 5.0 by Exactly what I needed I purchased this to make a magnetic board for my granddaughter. I painted it with chalkboard paint then framed it out with some brightly painted 1x2 poplar to cover the sharp edges. It is much larger and much less expensive than readymade magnetic it looks better! May 20, 2014
Rated 5.0 out of 5.0 by Great Product Using this to protect a table from stray coals when I BBQ with my small BBQ. Works perfct August 19, 2015
Rated 5.0 out of 5.0 by Just what I needed The drip pan under my gas grill had rusted out. I needed a sheet of galvanized steel to rebuild it. This product cuts easily, bends easily when scored with a utility knife, and was easy to hold in place with pop rivets. It's been out in the weather for over a month with no sign of rust.

Rated 5.0 out of 5.0 by Strong with application The size of the metal was prefect for patching a hole around an exhaust pipe September 16, 2014
Rated 4.0 out of 5.0 by Used to build model aircraft Material was flat and wrinkle or dent free. No ugly labels to remove. I bond this material to a used hollow core door and use magnets to hold balsa parts in position while building model aircraft. Works great and more details of the method can be found on the web.

Rated 5.0 out of 5.0 by good sheet stock for price Works o.k. for my application, (fabricating covers after air duct access) Could be slightly heavier gage, but seems to work well. January 14, 2014
Rated 4.0 out of 5.0 by Used to repair gas grill The grease pan on my gas grill was rusted out. Used this to make new grease pan. Wish I could have found in a heavier gauge, but so far product is doing the job. I cut out the pan with sheet metal snips, folded edges with 1/2in lip. drilled holes for drip cup. Works great.
