Portable Metal Roof Roll Forming Machines

Overview of Portable Metal Roof Roll Forming Machines

Portable metal roof roll forming machines are equipment used to produce metal roofing panels and related products through an efficient, continuous roll forming process. These machines form metal coil stock into customized panel profiles by progressing the strip through consecutive sets of roller dies. The key advantages of portable roll formers are:

  • Flexibility: Portable roll forming equipment can be moved and set up for production at the installation site, providing flexibility compared to fixed in-place machines.
  • Efficiency: Roll forming creates finished panels in a continuous process, avoiding inefficient stop-start press forming. Production rates can reach 130 feet per minute.
  • Customization: Roll formers use changeable roller dies that can form complex profiles, emboss patterns, and create various edge details on metal roof panels.
  • Cost Savings: Portable roll forming avoids costs of transporting bulky panels from the factory to install site. Operators can produce exactly required lengths.
  • Quality: Roll formed panels have excellent flatness and dimensional accuracy. The automated process ensures consistency.

Portable roll forming is ideal for producing metal roofing for commercial buildings, residential homes, or industrial sheds in custom lengths on-site. These versatile machines produce roofing, siding, steel studs, decking, purlins, solar panel frames and various architectural cladding profiles.

Main Components of a Portable Metal Roof Roll Forming Machine

A portable roll former comprises of the following components:

  • Decoiler: This uncoils and feeds the flat metal coil strip into the roll former. Decoilers with automatic loop control are optimal.
  • Feeding Table: This positions and guides the strip for accurate entry into the forming section. Tables may have powered drives.
  • Forming Section: The heart of the machine with consecutive roller stations that gradually shape the profile.
  • Cutoff Press: Cuts the formed panels to preset lengths or manually using a foot pedal.
  • Hydraulic System: Provides power for the presses and controls the precision roller gaps.
  • Control Panel: Allows operators to adjust forming parameters and production settings.
  • Frame: Supports the components in alignment on a portable chassis. Robust frames prevent vibration.
