Types of Metal Roof Panel Roll Forming Machines

Metal roof panel roll forming equipment is available in a range of configurations, automation levels and capabilities to suit different production needs, volumes and metal profiles.

The main types of these machines include:

TypesDescription
Manual LinesBasic roll formers for small scale production. Manual loading and offloading of raw coils and formed panels. Suitable for small workshops and manufacturers.
Semi-automatic LinesAutomated decoiling and coil feeding but manual offloading. Higher output than manual lines. Good for medium production volumes.
Fully Automatic LinesAutomated material handling and production from loading to unloading. For high volume continuous production. PLC and HMI systems for control.
CNC Roll Forming LinesCNC controlled production for precision forming as per programmed profiles, angles and dimensions. Ideal for custom profiles.
Double Deck Roll Forming LinesTwo production flows parallelly double the output. One coil feeding line serves both upper and lower rolling lines.
Specialty LinesTailored lines for specialized roofing components like rain gutters, flashing, eaves, ridges etc.
Portable Roll Forming MachinesCompact machines for onsite small-scale forming and repairs/retrofits.

Choosing between manual, semi-automatic and fully automatic lines depends on factors like:

  • Required production volume (linear meters per day/shift)
  • Frequency of profile changeovers
  • Available budget and space
  • Level of process automation needed
  • Number of workers/operators
  • Type of metal sheets – thickness, hardness, width etc.

Fully automated roll forming lines offer the highest productivity but involve higher investment costs. Manual and semi-automatic lines provide economical solutions for small roofing manufacturers and workshops.
