Stainless Steel I Beams
JCNMetal — Precision Hot Rolled Stainless Steel I Beams • Certified Quality • Advanced Dimensional Accuracy
Precision-Formed Stainless Steel I Beams
At JCNMetal, we produce stainless steel I beams using precision hot rolling and strict dimensional calibration. Every beam is tested by ultrasonic inspection to ensure internal integrity and straightness. With surface finishing options like pickling or sand blasting, our beams provide exceptional corrosion resistance, weldability, and mechanical strength for industrial and structural applications.
Accurate Forming and Alignment
At JCNMetal, stainless steel I beams are produced through hot rolling, welding, or press bending, selected according to size range and structural demand. Each route is precisely controlled to maintain straightness, symmetry, and uniform strength. After forming, beams are calibrated through multi-roll alignment systems to remove residual stress and ensure consistent geometry for reliable industrial and architectural performance.

We Help You Avoid Common Problems
Our goal is simple —
Built to ensure structural precision and lasting stability in every beam.
| Typical Fabrication Challenges | How We Solve It |
|---|---|
| Beams bend or twist during cutting, welding, or installation | Multi-roll straightening and controlled cooling relieve internal stress and keep perfect alignment throughout handling. |
| Web or flange distortion affects load-bearing accuracy | Each beam undergoes laser dimensional scanning and edge calibration to maintain uniform geometry and strength distribution. |
| Residual burrs or uneven ends complicate on-site fitting | Precision trimming and end milling deliver clean, square edges for fast, accurate assembly. |
| Irregular beam lengths disrupt structural planning | Automated length control with digital verification ensures batch-to-batch consistency for seamless installation. |
| Extended lead time delays large-scale projects | Streamlined production scheduling and stocked standard sections guarantee quick turnaround and dependable delivery. |
