Key Advantages & Customer Benefits
- Enhanced Flow Efficiency: The spiral punched design creates a continuous opening that minimizes pressure drop while maximizing fluid or air passage — ideal for filter cores, heat exchangers, and spargers.
- Reduced Clogging: Compared to round holes, the spiral slots allow debris to pass through more easily, reducing maintenance frequency in filtration and drainage applications.
- Corrosion Resistance: 304 grade stainless steel withstands moisture, chemicals, and temperature variations, ensuring long service life even in harsh environments like marine, food processing, or chemical plants.
- Versatile Use Cases: Suitable for protective sleeves for cables/hoses, architectural handrails, ventilation grilles, laboratory equipment, and agricultural irrigation drippers.
- Easy Fabrication: The tube can be cut, welded, bent, or threaded without compromising the structural integrity — compatible with standard metalworking tools.
- Cost-Effective Solution: As a manufacturer with 25+ years of experience, we offer competitive pricing without sacrificing quality. Direct factory supply reduces middleman costs.
Every tube is produced under strict quality control from raw material sourcing to final packaging. Our spiral punched tubes are packed in sturdy bundles to prevent damage during transit. We can also provide custom packaging options, including wooden crates or pallets, for large orders.

Q: What is the lead time for standard 5m tubes?
A: For standard stock sizes, we can ship within 7–10 days after order confirmation. Custom lengths or special finishes may require 15–20 days depending on quantity. -
Q: Is this tube suitable for high-pressure applications?
A: The 0.8mm wall thickness offers moderate pressure resistance. For high-pressure systems, we recommend thicker walls or alternative materials. Please consult our engineers for specific requirements. -
Q: Can the spiral punched tube be used for food contact?
A: 304 stainless steel is generally considered food-safe. However, we recommend confirming with local regulations. Our standard finish is mill finish, which is clean and suitable for most food processing environments. -
Q: Do you provide certificates of material or quality?
A: Yes, we can provide a material test certificate (MTC) for each batch upon request, ensuring traceability and compliance with industry standards. -
Q: What is the maximum length you can produce?
A: Our standard length is 5m, but we can produce up to 6m per piece depending on the diameter. For longer continuous lengths, multiple tubes can be welded or joined. -
Q: How do you pack the tubes for export?
A: Tubes are bundled with steel straps, wrapped in waterproof paper, and placed in pallets or wooden crates to prevent scratches and bending. Custom packaging is available. -
Q: Can I order a different hole size or pattern?
A: Yes, we offer customization. The hole diameter can be adjusted within a range (0.5mm – 3mm), and the spiral pitch can be modified. Minimum order quantity may apply for custom tooling.
