.080 Aluminum treadplate Metal Sheet Plate - 12 x 36 x .080- Flat Plain Plate Panel Fine Polished to a Bright Finish and Deburred. All of our metal is squared cut from mill sheets and then edge sanded to remove burrs from shearing. This is a beautiful piece of metal. Raised tread bright diamond pattern on the surface provides excellent traction. Common applications include truck beds, support structures, catwalks, and trench covers. This is an excellent choice if looking for a corrosion resistant material. 3003-H22 aluminum is 3003 aluminum in the H22 temper. To achieve this temper, the metal is strain hardened, and then partially annealed, to a strength that is roughly a quarter of the way between annealed (O) and full-hard (H28)
