Product Description

The 304 stainless steel perforated sheet with staggered perforations has an unpolished (mill) surface. The 304 stainless steel grade provides good strength and weldability, and is resistant to corrosion. It is typically nonmagnetic. 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.
