Foshan Xinliheng Stainless Steel Tube Factory
High-Precision Stainless Steel Special-Shape Tubes (SUS201 / SUS304)
Tight Tolerances. Dual Material Options. Engineered for Machinery & Architectural Excellence.
🔍 When Standard Tubes Don’t Fit — Precision Meets Performance
±0.05mm Accuracy. Industrial Strength. Decorative Finish. Built for Demanding Applications.
Introducing High-Precision Stainless Steel Special-Shape Tubes —
engineered for projects where dimensional accuracy, structural integrity, and surface perfection are non-negotiable.
Available in SUS201 (cost-effective) or SUS304 (premium corrosion resistance), our custom-profile tubes are manufactured to tight tolerances (±0.05mm–±0.1mm) using advanced cold drawing, roll forming, and CNC shaping technologies.
Perfect for precision machinery, automation systems, handrails, balustrades, and high-end architectural details, these tubes deliver consistent performance in both industrial hardware and aesthetic-driven construction.
✨ Not just a tube — a precision component.
✅ Why Choose Our High-Precision Stainless Steel Profile Tubes?
1. Ultra-Tight Tolerances – Built for Engineering Excellence
We specialize in high-accuracy profiles that ensure seamless integration into complex assemblies:
| Parameter | Standard Tolerance | High-Precision Option |
|---|---|---|
| Outer Diameter / Width | ±0.1mm | ±0.05mm |
| Wall Thickness | ±0.08mm | ±0.03mm |
| Straightness | ≤1.5mm/m | ≤0.8mm/m |
| Length | ±1mm | ±0.5mm |
🔧 Ideal for:
- Linear guide rails
- Sensor mounting frames
- Robotic arms
- Sealing channels
- Hidden structural supports
✅ All tubes undergo 100% dimensional inspection via laser micrometers and CMM (Coordinate Measuring Machine).
2. Dual Material Options – Optimize for Function & Budget
| Grade | Best For | Corrosion Resistance | Cost Efficiency |
|---|---|---|---|
| SUS201 | Indoor machinery, dry environments, cost-sensitive industrial parts | Moderate | ✅✅✅ (Most Economical) |
| SUS304 | Outdoor structures, food processing, pharmaceuticals, marine interiors, high-humidity zones | High | ✅✅ (Premium Durability) |
💡 Use 201 for internal machine frames. Use 304 for visible, exposed, or hygienic applications.
3. Multi-Application Versatility – From Factory Floor to Luxury Space
Our high-precision tubes serve two high-value markets with one product line:
⚙️ Mechanical & Industrial Hardware Applications
- Automation equipment frames
- Conveyor support rails
- Hydraulic & pneumatic cylinder guides
- Enclosure profiles for electronics
- Medical device components
- Automotive sensor mounts
🏗️ Architectural & Decorative Engineering
- Precision handrail connectors
- Hidden mounting rails for glass or panels
- LED light channels with tight fit
- Luxury elevator trims
- Designer furniture joints
- Seamless wall/ceiling runners
✨ Same tube. Same precision. Two worlds of application.
4. Custom Shapes – Beyond Round & Square
We manufacture any cross-sectional profile to your exact design:
| Shape Type | Examples |
|---|---|
| Standard Profiles | Round, Square, Rectangular, Flat |
| Custom Industrial | D-Shaped, T-Beam, U-Channel, I-Section |
| Decorative-Ready | Concave, Fluted, Wave-Edge, Asymmetric |
| Hybrid & Functional | Multi-cavity, snap-fit, cable-integrated |
👉 Send your CAD file, DXF, or sketch — we’ll design the tooling and deliver samples in 7–10 days.
5. Premium Surface Finishes – For Function & Aesthetics
Choose from a range of finishes to match your application:
| Finish | Appearance | Best For |
|---|---|---|
| 2B (Standard) | Smooth, matte | Internal machine parts |
| BA (Bright Annealed) | Reflective, clean | Precision equipment |
| Hairline Brushed (HL #180–320) | Elegant, scratch-resistant | Handrails, interiors |
| Mirror Polished (8K) | Chrome-like shine | Luxury displays, elevators |
| PVD Color Coating | Gold, Black, Rose Gold, Bronze | Branded environments |
| Electropolished | Ultra-smooth, hygienic | Food, pharma, medical |
✅ All finished surfaces include anti-scratch protective film.
