Key Product Features and Technical Specifications
- Material Grades: Choose between AISI304 (general corrosion resistance) and AISI316 (superior resistance to chlorides and chemicals) for optimal performance in your specific environment.
- Polished Surface: Available from 180G to 600G grit finish, or mirror polish upon request. The smooth surface prevents dirt accumulation and simplifies cleaning, making it perfect for decorative use.
- Precision Welding: Our pipes are manufactured using TIG welding followed by bright annealing, resulting in a seamless appearance and strong weld seam free from defects.
- Dimensional Accuracy: Tight tolerances ensure consistent outer diameter and wall thickness, facilitating easy installation and fitting with existing components.
- Customization: We offer a wide range of outer diameters (6mm–219mm), wall thickness (0.5mm–6.0mm), and lengths (1m–12m). Round, square, and rectangular profiles are available. Custom shapes and sizes are welcomed.
- Corrosion Resistance: Both AISI304 and AISI316 perform excellently in indoor and outdoor environments. For coastal or industrial areas with high chloride exposure, AISI316 is recommended.
- Application Versatility: Ideal for architectural ornamentation, stair railings, balcony fences, door and window frames, furniture legs, exhibition stands, and interior trim.

Frequently Asked Questions (FAQ)
- 1. What is the difference between AISI304 and AISI316 for decorative pipes?
- AISI304 offers excellent general corrosion resistance and is cost-effective for most indoor and outdoor applications. AISI316 contains molybdenum, providing superior resistance to chlorides (e.g., sea air, de-icing salts) and chemicals, making it ideal for coastal or industrial environments.
- 2. Can you provide pipes with a mirror polish?
- Yes, we offer mirror polished surface finish typically up to 600G or higher upon request. The mirror finish gives a highly reflective, decorative appearance suitable for luxury interiors.
- 3. What lengths and custom sizes are available?
- Standard lengths are 6m and 12m, but we can cut to any length from 1m to 12m. Custom outer diameters, wall thicknesses, and shapes (square, rectangular, oval) can be produced with a minimum order quantity. Please contact us with your specific requirements.
- 4. Are your pipes suitable for outdoor use in coastal regions?
- Yes, our AISI316 grade pipes are highly recommended for coastal areas due to enhanced resistance to saltwater corrosion. We also apply a pickling and passivation treatment to maximize longevity.
- 5. What certifications do your products hold?
- Our factory is certified under ISO9001 (quality), ISO14001 (environment), OHSAS18001 (occupational health), HACCP (food safety), and others. Each batch can be supplied with a mill test certificate upon request.
- 6. What is the typical lead time for an order?
- For standard sizes and finishes, lead time is approximately 15–25 days depending on quantity. Customized orders may require 25–35 days. We work closely with our logistics partners to ensure timely delivery.
- 7. Do you offer free samples?
- Yes, we can provide a small sample (e.g., 30cm length) for quality evaluation. The sample is free, but the customer is responsible for shipping costs. Contact our sales team to arrange.
- 8. How do you ensure the weld seam quality and surface consistency?
- We use automated TIG welding with internal gas purge to achieve a clean weld. Every pipe undergoes visual inspection, pressure testing (if required), and surface roughness measurement. Our quality control team follows a strict sampling plan per batch.
