Stainless Steel Angle Bar
JCNMetal — Stainless Steel Angle Bar Manufacturer • Supplying 60+ Countries Worldwide
Precision-Formed Stainless Steel Angle Bars
At JCNMetal, we produce stainless steel angle bars with stable cross-section and precise angles formed by controlled hot rolling and straightening. Each bar is measured along its full length to maintain tight dimensional accuracy and clean edges, ensuring reliable fit and long-term strength in structural fabrication.
Accurate Forming and Straightening
Hot rolling with balanced pass design reduces uneven leg strain, and finishing at controlled temperatures limits residual stress. During cooling, laminar water sprays cool both legs uniformly; multi-roll straightening sets counter-twist and flattens edges, so the bars keep accurate angles and straightness instead of warping.

We Help You Avoid Common Problems
Our goal is simple —
You Get Angle Bars That Fit Straight, Weld Clean, and Assemble Precisely.
| Typical Fabrication Challenges | How We Solve It |
|---|---|
| Bars twist or lose angle accuracy during cutting or welding | Balanced rolling and straightening relieve stress and stabilize geometry, preventing distortion during fabrication. |
| Uneven leg thickness causes misalignment in assemblies | Calibrated pass design ensures both legs remain uniform in thickness and angle, simplifying fit-up and reducing rework. |
| Rough or burred edges damage tools and slow welding | Precision trimming and finishing deliver smooth edges that protect tooling and create cleaner weld joints. |
| Variations in length or tolerance disrupt fabrication layout | Continuous dimensional checks and fixed-length cutting maintain consistency across every batch. |
| Delayed deliveries hold up fabrication schedules | Stocked materials and flexible production lines support on-time supply for urgent fabrication projects. |
