Perforated metals are mostly manufactured in steel carbon, but also can be manufactured on a custom aluminum, stainless steel, galvanized steel, and so on.
We perforate a wide range of round, square, slotted, decorative and even odd shaped perforations from a numerous metal sheets. The most common percentage of open area is between 30% and 50% although more extreme open areas are available depending on the perforation. Some times the percentage open area has to be kept lower for increased strength and flatness of the perforated metal sheet especially when galvanising
