- Customizable to Your Exact Needs: No minimum order quantity for custom sizes; we support prototyping and small batch production.
- Quality Assurance: Every tube undergoes inspection for hole size, density, and surface finish before shipment.
- Global Shipping: We export from major Chinese ports (Tianjin, Qingdao, Shanghai, Foshan) with reliable logistics partners to over 20 countries.
Our tubes are used in industries such as water treatment, food & beverage, mining, construction, and automotive. For example, as a filter element in industrial dust collectors, a liquid strainer in chemical processing, or a decorative cladding in modern architecture. The 304 grade ensures long-term performance even in humid or mildly corrosive environments.
Frequently Asked Questions
Q1: Can I get a sample before placing a bulk order?
Yes, we provide samples upon request. Sample cost is negotiable, and shipping charges apply. For custom sizes, we can produce a short piece (e.g., 300mm) for your evaluation.
Q2: What is the minimum order quantity (MOQ)?
For standard sizes (4m length, common diameters), MOQ is 50 pieces. For fully customized tubes, MOQ may be 100 pieces, but we can discuss based on your project.
Q3: Are the holes precisely round and burr-free?
Yes, our CNC perforation process produces clean, burr-free holes with tight tolerances. We can also perform deburring if required.
Q4: Can you make tubes with different hole sizes in one tube?
Yes, we can produce tubes with multiple hole sizes or patterns, but this requires a custom tooling setup. Please contact our sales team for feasibility.
Q5: What packaging do you use for export?
Each tube is wrapped in protective foam or plastic, then packed in wooden crates or steel bundles to prevent damage during transit. We also offer custom packaging upon request.
Q6: How long does production take?
Standard production time is 15–20 days after order confirmation and deposit. Custom orders may take 25–30 days depending on complexity.
Q7: Is 304 stainless steel food-grade?
Yes, 304 stainless steel is widely accepted as food-grade material. Our tubes are manufactured with clean surfaces, suitable for food contact applications.
Q8: Do you provide technical drawings or CAD files?
Yes, we can provide dimensional drawings upon request. For custom designs, we work with your specifications to ensure accuracy.
