Stainless Steel Coil Tube – Regional Manufacturer Grade (Third-Tier Supply)
Product Overview
The Stainless Steel Coil Tube offered by Wenzhou Jixing Metal Materials Co., Ltd. is a cost-effective coiled tubing solution sourced from a network of regional manufacturing facilities located across Wenzhou, Foshan, and Taizhou — three of China's most established hubs for stainless steel processing. Positioned within the Third-Tier Supplier Framework, this product line is engineered for civil, low-pressure, and decorative-grade applications where competitive pricing is the primary procurement driver.
This coil tube represents the most accessible entry point into stainless steel tubing procurement, delivering functional performance at the lowest market price point. It is ideally suited for projects with moderate technical requirements, non-critical structural roles, and high-volume decorative or architectural installations.
Material & Properties
The coil tube is manufactured primarily from austenitic stainless steel grades, with the following commonly available options:
- Grade 201 – Economy austenitic grade offering adequate corrosion resistance for indoor decorative and civil applications
- Grade 304 – General-purpose austenitic stainless steel with superior corrosion resistance and formability
- Grade 304L – Low-carbon variant of 304, suitable for environments where sensitization is a concern
- Grade 316 – Molybdenum-enhanced grade for improved resistance to chloride-induced corrosion
Key Material Characteristics:
- Excellent formability and bendability, ideal for coil-based fabrication workflows
- Smooth surface finish suitable for decorative and architectural finishing
- Natural corrosion resistance eliminating the need for additional coatings in most environments
- Non-magnetic properties in annealed condition
- Recyclable to 100%, supporting sustainable construction practices

Manufacturing Process
The coil tube is produced through a continuous cold-drawing and forming process, which offers significant advantages in production efficiency and material utilization:
- Raw Material Preparation – Stainless steel strip or wire is sourced from certified mill suppliers and inspected for composition and dimensional tolerance.
- Cold Drawing – The raw material is drawn through precision dies to achieve the target outer diameter and wall thickness with controlled tolerance.
- Forming & Welding – The drawn tube is formed into the desired cross-sectional profile. Welded coil tubes are produced using automatic TIG (Tungsten Inert Gas) welding to ensure seam integrity.
- Heat Treatment / Annealing – Tubes are annealed to relieve residual stresses and restore full austenitic microstructure for optimal ductility and corrosion resistance.
- Pickling & Passivation – Surface oxide layers are removed through acid pickling, followed by passivation to enhance corrosion resistance.
- Coiling & Packaging – The finished tube is wound onto standard cores and packaged with protective wrapping to prevent surface damage during transit.
As a Third-Tier regional supplier, the production infrastructure leverages the concentrated expertise of the Wenzhou–Foshan–Taizhou industrial corridor, enabling rapid turnaround and flexible order quantities.
Applications
Given its positioning as a cost-optimized, civil-grade coil tube, this product is widely deployed across the following sectors:

Important Procurement Advisory
Buyers are advised that Third-Tier regional coil tube products are optimized for price-sensitive, civil-grade, and decorative applications. Quality consistency may vary between production batches due to the distributed nature of the regional manufacturing network. For critical applications involving high pressure, elevated temperatures, or stringent regulatory compliance (e.g., food-grade, medical, or aerospace), buyers should request batch-specific test reports and consider upgrading to Tier-1 or Tier-2 supplier products. Wenzhou Jixing Metal Materials Co., Ltd. recommends conducting sample qualification and destructive testing on initial orders to confirm suitability for the intended application.
