where can i get a thick sheet of steel ? and is steel bullet proff for example if you shoot a bullet on steel will that bullet bounce right off the steel ?
Try a local Fastenal store, they can order it for you by the sheet. If that doesnt help, then try a welding or fabricating store.
Try the business-to-business yellow pages in your area. A local hardware store can also tell you who to contact. Or search steel plate or sheet metal on the internet to find a local supplier. No, sheet steel is not bullet proof, unless you get heavy plate. Depending on how thick it is, the plate will deform if hit by a high velocity bullet, but usually not enough to matter. Bullets have velocities from about 500 ft/sec up to roughly 3000 ft/sec, depending on the type of weapon used. I wouldn't try to use anything thinner than 3/4 inch. You'll have to experiment and see what it will actually stop. I can't guarantee it'll stop a high-velocity rifle slug. Try it and see.
