Solar Strut Channel Forming Machine — High-Speed Production Line for Photovoltaic Mounting Systems
Why Choose a Solar Strut Channel Forming Machine?
A solar strut channel forming machine is the production line that turns galvanized or pre-painted steel coil into slotted U-channel profiles — the structural backbone of every solar panel mounting system. According to SEIA, each megawatt of utility-scale solar requires 2.5–4.5 tonnes of strut channel, which makes production speed and hole-pattern accuracy the two most critical cost drivers for solar contractors .
Wadjay’s solar strut channel line integrates decoiling, leveling, servo feeding, online punching, roll forming, and hydraulic tracking cutting into one fully automated workflow, producing 41×41mm and 41×21mm profiles (custom sizes available) from 1.5–3.0mm steel strip at speeds up to 25 meters per minute .

How the Solar Strut Channel Production Line Works
The Wadjay solar strut channel forming machine follows a fully synchronized cold roll forming cycle :
- Decoiling — hydraulic or manual decoiler (3–5 ton capacity) releases the steel strip
- Leveling — 7-roller leveling device corrects strip flatness and eliminates internal stress
- Servo Feeding — Yaskawa/Japan servo motor feeds strip precisely into the punching press according to programmed hole patterns
- Online Punching — press machine executes slot holes, bolt holes, and drainage holes with ±0.5mm accuracy
- Roll Forming — 20–24 stations progressively bend the strip into the C/strut channel cross-section via gearbox transmission
- Hydraulic Tracking Cutting — flying cut or servo tracking saw cuts to length without stopping the line
- Discharge — finished 41×41 / 41×21 strut channels are collected on the output table
The entire process is orchestrated by a PLC + HMI touchscreen, allowing operators to set length, quantity, hole pattern, and production speed with minimal training.
Application Scenarios：solar strut channel forming machine
Solar strut channels produced by this machine are the “skeleton” of photovoltaic power stations :
- Large-scale ground-mount solar farms — C-channel and U-channel as main beams and purlins for desert, mudflat, and mountain PV stations; demand is massive with uniform specifications
- Rooftop solar mounting systems — rails for ballasted or penetrated commercial/industrial roof installations
- Solar carports — overhead canopy structures requiring robust spanning channels
- Electrical & cable management — cable trays, wiring supports, component installation
- Industrial & construction — machinery support, warehouse racking, modular construction systems
The cold roll forming process increases the yield strength of the metal, delivering superior strength, durability, and up to 15% material scrap reduction compared to traditional welding and cutting processes .
Why Wadjay’s Solar Strut Channel Machine Stands Out
- Multi-profile production — one machine produces 41×41, 41×21, 41×52, 41×62 and custom sizes via quick-change tooling or servo adjustment
- High-speed output — 25 m/min forming speed with servo flying punch, daily capacity exceeds 10 tonnes per single line
- ±0.5mm hole accuracy — critical for perfect compatibility of solar clamps and rail connectors on site
- Industrial-grade drivetrain — 22–30kW gearbox drive with ∅80mm 45# forged shafts for vibration-free continuous operation
- Premium rollers — Cr12MoV / GCr15, hard chrome plated to HRC58–62° for extended service life
- Intelligent PLC control — Siemens or Mitsubishi PLC with HMI, automatic length/quantity setting, fault alarm system
- Flexible punching options — online hydraulic punching, mechanical press punching, or offline punching per customer preference
- Global export experience — machines installed in USA, Germany, India, Brazil, Turkey, UAE, Vietnam, Malaysia, Australia
Frequently Asked Questions
Q1: Can this machine produce both 41×41 and 41×21 strut channel sizes?
A: Yes. Wadjay’s solar strut channel forming machine uses quick-change tooling or servo adjustment to switch between 41×41mm, 41×21mm, 41×52mm, 41×62mm, and other custom NEMA sizes — one machine covers your full profile range .
Q2: What is the actual production speed and daily capacity?
A: Standard forming speed is 10–20 m/min, with high-speed servo flying punch configuration reaching 25 m/min. A single line can produce over 10 tonnes per day .
Q3: How accurate are the punched holes?
A: Hole accuracy is ±0.5mm with flying punch and ±0.3mm with servo press — well within the tolerance required for solar clamps and rail connectors .
Q4: What material thickness and type can be processed?
A: The machine handles 1.5–3.0mm galvanized steel (GI), galvalume (GL), and pre-painted steel (PPGI) meeting ASTM A653 or EN 10346. Optional configuration extends to 4.0mm for heavy-duty applications .
Q5: Is the machine customizable for my local voltage and profile drawings?
A: Absolutely. Voltage (380V/50Hz/3-phase or as required), profile dimensions, hole patterns, and even machine color can be fully customized. Send us your strut channel drawing and we’ll engineer the tooling accordingly.
