Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with over two decades of expertise in metal perforation and wire mesh production. Our 304 Stainless Steel Perforated Sheet (1.2mm thick, 8mm hole diameter, 12mm pitch) is specifically engineered for high-quality ventilation panels, offering a perfect balance of airflow efficiency and structural integrity. With an annual export value of US$5-10 million and serving markets across North America, Europe, Southeast Asia, and beyond, we deliver precision-crafted sheets that meet the demanding requirements of industrial, commercial, and architectural applications.
This perforated sheet is fabricated from premium grade 304 stainless steel, known for its excellent corrosion resistance, durability, and hygienic properties. The 1.2mm thickness provides robust strength while maintaining lightweight characteristics, making it ideal for ventilation panels in HVAC systems, enclosures, and equipment guards. The 8mm round holes with 12mm pitch ensure optimal open area for airflow, dust filtration, and noise reduction, while the uniform pattern enhances aesthetic appeal and functional performance.

Product Features & Benefits
- Superior Corrosion Resistance: 304 stainless steel offers excellent protection against rust, chemicals, and moisture, making it suitable for indoor and outdoor ventilation systems, including kitchens, industrial plants, and marine environments.
- Precise Hole Pattern: The 8mm round holes with 12mm pitch are produced using advanced CNC punching technology, ensuring consistent spacing and smooth edges without burrs, reducing air resistance and enhancing safety.
- High Strength-to-Weight Ratio: Despite being only 1.2mm thick, the sheet maintains structural rigidity, capable of withstanding mechanical stress while remaining lightweight for easy handling and installation.
- Optimal Airflow Performance: With approximately 40% open area, these perforated sheets allow efficient air circulation, heat dissipation, and dust filtration, ideal for ventilation louvers, equipment panels, and acoustic enclosures.
- Versatile Customization: We offer custom sheet sizes, hole shapes (square, slotted, hexagonal), staggered patterns, and edge treatments (flat, angled, or rounded) to match your specific project needs.
- Hygienic & Easy to Clean: The smooth surface and non-porous nature of stainless steel prevent bacterial growth, making it perfect for food processing, medical, and cleanroom ventilation panels.
- Long Service Life: 304 stainless steel perforated sheets have a lifespan of 20+ years under normal conditions, reducing replacement costs and maintenance efforts.
