About 3003 Aluminum Perforated Sheet, Unpolished
The 3003 aluminum perforated sheet with staggered perforations has an H14 temper and an unpolished (mill) surface. The 3003 aluminum alloy provides good strength and corrosion resistance, and is lighter weight than steel, copper, and brass. The sheet has an H14 temper, meaning it has been strain hardened to a 1/2 hard temper. The perforations are staggered in parallel diagonal rows. Perforated metal sheets are created by punching a series of holes in a solid material. The holes are typically round, square, or slotted, but other patterns include hexagonal, Grecian, and cane. Holes are staggered (in parallel diagonal rows) or straight (in parallel vertical and horizontal rows). A sheet’s perforation size, center spacing, and percent open area (ratio of open space to total space in a given area of expanded metal) will all affect the particle size and the amount of light, sound, air, and liquid that can pass through.
