Expert Opinions
- Dr. Emily Zhou, Associate Professor, Cold-Formed Steel Structures, Tsinghua University
- “For CZ purlins, consistency in corner radii and web flatness is as critical as grade selection. AI-based pass tuning stabilizes geometry through coil variation and temperature drift.”
- Marco Lenti, Director of Automation, Dallan Group
- “Servo cassettes and absolute encoders have matured. The real gain is in data—once recipes are locked to coil metadata, first-piece acceptance becomes routine.”
- Jason Patel, Senior Structural Engineer, Steel Tube Institute Technical Council
- “When moving to HSLA ≥500 MPa, verify hole-edge quality and bearing strength at connections. Slight punch/die optimization often preserves capacity without thicker sections.”
