| 1.3 Production Process | |
| Flow Chart: Hydraulic Decoiler → Entry Guide → Roll Former → Hydraulic Cutter → Out Table | |
| Process: The KR18 roll former shapes flat steel coils into precise standing seam panels. Chain-driven rolls and a cast-iron frame provide stable, high-precision forming. The hydraulic cutter accurately trims panels to length. Diesel power allows on-site operation. The line ensures consistent seam height, tight tolerances, and rapid production for roofing construction projects. |
