Perforated metal is one of the most versatile and popular metal products on the market today. Perforated sheet can range from light to heavy gauge thickness and any type of material can be perforated, such as perforated carbon steel.

Perforated metal is versatile, in the way that it can have either small or large aesthetically appealing openings. This makes perforated sheet metal ideal for many architectural metal and decorative metal uses. Perforated metal is also an economical choice for your project. Our perforated metal filters out solids, diffuses light, air, and sound. It also has a high strength-to-weight ratio.

Possible Alternative Grades

Grade	Why it might be chosen instead of 304
301L	A higher work hardening rate grade is required for certain roll-formed or stretch formed components.
302HQ	Lower work hardening rate is needed for cold forging of screws, bolts, and rivets.
303	Higher machinability needed, and the lower corrosion resistance, formability, and weldability are acceptable.
316	Higher resistance to pitting and crevice corrosion is required, in chloride environments
321	Better resistance to temperatures of around 600-900 °C is needed…321 has higher hot strength.
3CR12	A lower cost is required, and the reduced corrosion resistance and resulting discoloration are acceptable.
430	A lower cost is required, and the reduced corrosion resistance and fabrication characteristics are acceptable.
