Key Technical Features
Advanced high-frequency welding and sizing control ensure precise outer diameters and wall thicknesses, minimizing installation misalignment and labor costs on site.
Continuous high-frequency resistance welding (ERW) provides uniform structural strength and reliable load-bearing performance under dynamic loads.
Q235, Q345, S235 and S355 provide balanced strength and ductility, allowing easier fabrication, welding and on-site installation.
Tailored lengths, custom wall thicknesses, and diverse cross-sections seamlessly adapt to complex architectural and solar mounting configurations.

FAQ
Q: What is your Minimum Order Quantity (MOQ) for custom sizes?
A: Answer: Generally 5 metric tons per specification. However, we accept smaller trial orders or mixed-size containers to support initial project testing.
Q: Do you provide free material samples for quality evaluation?
A: Answer: Yes, free standard samples (100mm–200mm length) are available. Clients only need to cover the international courier shipping cost.
Q: How do you pack the tubes for ocean freight to prevent corrosion or damage?
A: Answer: Standard export packaging includes strong steel strapping, waterproof plastic film wrapping, and optional wooden or woven bag protection for long-distance sea shipping.
Q: What are your standard payment terms for new international clients?
A: Answer: We typically accept T/T (30% deposit, 70% balance against the copy of B/L) or 100% irrevocable L/C at sight from reputable banks.
Q: Can you issue a Certificate of Origin (e.g., Form E, FTA) for customs clearance?
A: Answer: Yes, we can issue official Certificates of Origin, Chamber of Commerce invoices, and all necessary customs clearance documents upon shipment.
Q: Can you manufacture according to engineering drawings?
A: Yes. We manufacture according to customer drawings and specifications, including customized dimensions, punching patterns, end processing, and surface treatments.
Q: What inspection documents can you provide?
A: We can provide Mill Test Certificates (MTC/MTR), inspection reports, material certificates, coating thickness reports, packing lists, and certificates of origin based on customer requirements.
