Stainless Steel Slotted Perforated Sheet

Product Overview

As a leading stainless steel slotted perforated sheet manufacturer in China, we specialize in precision-engineered metal mesh solutions. Our products are crafted using CNC punching machines with custom molds, featuring elongated slot holes (also known as "oblong holes" or "oval holes") that balance functionality and aesthetics. These perforated panels are widely used in architectural cladding, safety guards, ventilation systems, and industrial filtration.
