As a leading manufacturer from Anping Xinye Metal Wire Mesh Products Co., Ltd, located in Hengshui, Hebei, China, we specialize in producing high-quality 304 Stainless Steel Perforated Metal Sheets with a precise 3mm hole diameter and 60% open area. Our sheets are engineered for demanding industrial filtration applications, delivering consistent performance, corrosion resistance, and long service life. With years of expertise in metal fabrication, we ensure every sheet meets strict dimensional tolerances and surface quality standards.
This perforated metal sheet is designed to provide an optimal balance between flow rate and mechanical strength. The 60% open area ensures efficient fluid or gas passage while maintaining structural integrity. The 3mm round holes are uniformly distributed in a staggered pattern to maximize open area and minimize pressure drop. Whether you need for liquid filtration, air intake screens, or powder sifting, our sheet offers reliable performance.
Below are the key features and technical specifications of our 304 stainless steel perforated sheet:

Our perforated sheets are manufactured using advanced CNC punching machines, ensuring consistent hole size and spacing. The deburring process guarantees safe handling and easy installation. The 304 stainless steel material offers excellent resistance to oxidation, acids, and alkaline environments, making it suitable for food processing, chemical filtration, water treatment, and pharmaceutical applications.
Benefits for Buyers:
- High Filtration Efficiency: 60% open area allows high flow rates while retaining particles down to 3 mm size.
- Durability: 304 stainless steel withstands harsh environments, high temperatures (up to 870°C in intermittent service), and mechanical wear.
- Versatility: Can be used as sieve plates, filter support grids, ventilation panels, soundproofing components, and decorative elements.
- Easy Maintenance: Smooth surface resists clogging and is easy to clean.
- Customizable: We offer custom sizes, thicknesses, hole patterns, and edge treatments to fit your exact requirements.
