The Solar Racking Roll Forming Machine is a fully automatic cold roll forming production line designed for manufacturing photovoltaic (PV) mounting structures, including solar rails, C/U/Z channels, strut channels (e.g. 41×41mm, 41×21mm), and custom brackets used in rooftop and ground-mounted solar installations. The integrated line performs decoiling, leveling, servo punching (for mounting holes & slots), continuous roll forming, and flying cut-to-length in one synchronized process—delivering high-precision, burr-free profiles with minimal material waste.

Inline Precision Punching: Hydraulic or servo punching unit creates round holes, oblong/slotted holes, and grounding holes with ±0.3mm positioning accuracy—ready for on-site bolt assembly.
Multi-Profile Capability: Available with fixed or quick-change cassette rollers to produce C-rails, U-channels, Z-purlins, and UNISTRUT-style slotted channels from the same line.
Heavy-Duty Forming Section: 16–24 forming stations with GCr15/Cr12MoV rollers (HRC 58–62, hard chrome plated) and 40Cr alloy shafts for consistent straightness and long tool life.
Non-Stop Flying Cut: Hydraulic flying shear or servo tracking cut ensures clean, burr-free cuts without stopping the line, maintaining continuous high-speed output.
PLC + HMI Control: Touch-screen interface allows batch programming of length, quantity, punching patterns, and production monitoring with encoder-based length tolerance within ±1mm.
