Whether you need a small batch for prototyping or large-scale production, our factory delivers consistent quality and on-time shipping from ports like Tianjin and Qingdao.
Key Features & Benefits
- Superior Material: 304 stainless steel provides excellent resistance to rust, acids, and high temperatures, ensuring long service life.
- Helical Perforation: The spiral pattern enhances strength and allows for smoother fluid or gas flow compared to straight perforations.
- Fully Customizable: Hole diameter (1-6mm), wall thickness (0.5-3mm), tube length, and even perforation density can be adjusted upon request.
- Versatile Applications: Used in water treatment, oil & gas filtration, chemical processing, food industry, architectural decoration, and soundproofing.
- Precision Manufacturing: Our advanced CNC perforation machines ensure tight tolerances (±0.1mm for hole size) and smooth edges without burrs.
- Low Maintenance: The smooth surface finish resists clogging and is easy to clean, reducing downtime.
