Decorative Tube Production Process
Our steel tube mills follow a precise, end-to-end workflow to ensure every tube meets the highest aesthetic and structural standards:
1. Forming Section
The flat stainless steel strip is gradually shaped into a tube using precision rollers, ensuring smooth curvature and consistent diameter.
2. Welding Section
Edges are fused using TIG or laser welding , creating a strong, clean seam with minimal heat distortion - essential for a seamless final finish.
3. Grinding & Polishing
After welding, the tube undergoes internal and external grinding to remove burrs. Optional polishing units can be integrated to achieve mirror, brushed, or matte finishes.
4. Sizing & Straightening
Tubes are precisely sized and straightened to eliminate any curvature, ensuring dimensional accuracy.
5. Cutting to Length
Automated flying cutters provide clean, high-speed cuts synchronized with the production line.
This entire process is highly automated , ensuring consistent quality and high throughput - ideal for both small-batch artisanal production and large-scale manufacturing.
