Stainless Steel Channel
JCNMetal — Stainless Steel Channel Bar Manufacturer • Serving Construction, Energy & Marine Industries Worldwide
Precision-Engineered Stainless Steel Channels
At JCNMetal, we manufacture stainless steel channels with precise U and C profiles formed by controlled hot rolling, welding, or press bending. Each channel ensures accurate dimensions, smooth surfaces, and strong load-bearing performance. With surface treatments like pickling or sand blasting, our channels deliver excellent corrosion resistance and long-term durability for structural and industrial use.
Accurate Forming and Straightening
Hot rolling and press bending are carried out with balanced pass design to distribute force evenly. During cooling, dual laminar water jets remove heat from both sides to avoid twisting. Channels then pass through multi-roll straightening that corrects residual stress and keeps precise alignment for structural use.

- Machinery and fabrication systems
- Marine and construction engineering
Surface Finishes
Pickled
Acid-cleaned surface removing oxide scale for a clean, uniform matte appearance.
Sand Blasting

We Help You Avoid Common Problems
Our goal is simple —
Built to deliver precision alignment and long-term reliability in every structure.
| Typical Fabrication Challenges | How We Solve It |
|---|---|
| Channels deform or twist after cutting or welding | Symmetric rolling and balanced cooling prevent internal stress and maintain straight geometry. |
| Uneven side thickness leads to poor alignment | Controlled forming ensures uniform wall thickness and web symmetry across full length. |
| Sharp edges or burrs slow welding and assembly | Precision edge trimming and deburring deliver smooth surfaces for clean, safe joints. |
| Inconsistent lengths disrupt installation layout | Automated measuring and fixed-length cutting ensure repeatable accuracy batch to batch. |
| Delays in delivery affect project progress | Large stock inventory and flexible scheduling secure fast, reliable shipment for urgent jobs. |
