Products Description

Our Advantages

1. Precise Dimensions
Each of our Hexagonal Stainless Steel Tubes undergoes rigorous dimensional testing, ensuring tolerances within ±0.05 mm.

2. Smooth Surface
Our Hexagonal Stainless Steel Tubes undergo a pickling and passivation treatment, resulting in a smooth, clean, and corrosion-resistant surface suitable for industrial and mechanical systems.

3. Customized Services
We offer surface treatments such as basalt coating (BA), polishing, and custom cutting. TORICH provides technical support, OEM, and ODM services, and provides customized planning solutions.We offer not only inner circle and outer hexagon, but also inner hexagon and outer circle, as well as other custom shapes.

4. Quality Control
Each of our tubes undergoes eddy current testing, hydrostatic pressure testing, and ultrasonic testing to ensure they are free of delamination, voids, or hidden cracks, and are resistant to high pressures.
