C Purlin Roll Forming Machine — Galvanized C Channel Purlin Line with AMS, Gearbox, Flying Shear & Hydraulic Cooling
Why Choose a C Purlin Roll Forming Machine?
A C purlin roll forming machine converts galvanized steel coil into C-channel purlins, wall beams and light steel studs in one continuous cold-forming line. It replaces manual shearing, separate punching and standalone bending, and is the core line for steel-structure workshops, warehouse roofing, wall systems, prefab framing and light-machinery brackets.
The Wadjay C-purline configuration (built on the C/Z/U light keel stud purlin platform) uses six integrated modules — AMS controls, hydraulic station with cooling unit, flying shearing device, decoiler, gearbox transmission and post cutting. For structural C purlins it processes 1.0–1.5mm galvanized sheet, yield strength up to 235MPa, runs up to 60 m/min, and holds ±1.0mm cutting tolerance on 6000mm length with 14 roller stands. For light-gauge C stud/keel work it can be configured for thinner strip and servo speeds, so one brand line serves both roofing purlin and drywall/interior framing orders.C purlin roll forming machine

How the C Purlin Line Works
- Decoiling — galvanized coil on decoiler; strip fed into guide/leveling without manual unrolling strain.
- Leveling & guiding — flatten web/flange/lip entry to reduce springback in C profile.
- Roll forming, 14 stands — gearbox-driven stands progressively form C web, flanges and lip; stand count supports standard roofing/wall C sections.
- AMS control loop — set batch quantity, profile program, target length and production count; switch C purlin vs light-keel C stud parameters from HMI.
- Flying shear + post cut — flying shear for continuous high-speed cut-to-length; post-cut station for final clean ends at ±1.0mm/6m.
- Hydraulic cooling & discharge — cooling unit stabilizes oil temperature on long shifts; finished C purlins go to receiving/stacking.C purlin roll forming machine
Application Scenarios
- Steel-structure workshops/warehouses — C purlins as roof beams and wall beams; C sections can also form light roof trusses, brackets, columns, beams and arms in light machinery.
- Commercial/industrial roofing — long-span C purlin sets where 6000mm ±1mm reduces on-site trimming.
- Drywall partitions & ceilings — C stud/U track/light keel when line is configured for 0.3–0.6mm servo stud mode.
- Prefab & export projects — GI keel/purlin standardization for Middle East, Africa, Latin America sites（documented markets: Iraq, Egypt, UAE, Chile, Zambia）.
- Light structural brackets — C profiles for frames, supports, racking arms.
Why Wadjay C Purlin Configuration Stands Out
- C-focused, platform-expandable — standard C purlin program; Z/U/stud optionally on same CZU platform to avoid buying separate lines.
- 60 m/min structural output — 1.0–1.5mm GI, yield ≤235MPa, suitable for high-volume roofing/wall purlin orders.
- 14-stand gearbox forming — synchronized stands for stable C web/flange/lip geometry at speed.
- Flying shear + post cut — continuous cutting without stopping the line, plus post-cut for clean end faces.
- Hydraulic cooling — maintains cutting pressure/oil temperature during long runs.
- ±1mm on 6m — less welding/installation rework in steel-structure purlin sets.
- AMS batch control — length, quantity and profile programs managed by one operator.
- 380/480V 50/60Hz, 65kW — adaptable to Asia, Middle East, Africa, Latin America site power.
- Material-saving angle — cold-bent C sections can deliver equivalent strength to traditional channel steel with up to ~30% material saving, lowering steel cost and dead load.
FAQs
Q1: What thickness and grade does the C purlin mode handle?
A: Structural mode 1.0–1.5mm galvanized steel, yield ≤235MPa. If you also make light C stud/keel, configure 0.3–0.6mm programs; servo light-keel lines commonly run 10–20m/min and up to 30–50m/min.
Q2: How fast and how accurate?
A: Max 60m/min in the 14-stand/65kW CZU-based configuration; cutting tolerance ±1.0mm on 6000mm length using flying shear + post cut.
Q3: Is it only C, or can it do Z/U/stud?
A: This page is optimized for C purlin. The same Wadjay CZU platform can be quoted for Z/U and light-keel C stud; pure C-only tooling is recommended if you never run Z/U to reduce changeover complexity.
Q4: What control and transmission?
A: AMS controls for length/quantity/profile programs; gearbox transmission across 14 stands. Siemens/Mitsubishi/AMS can be specified by configuration.
Q5: What about hydraulic and cutting?
A: Hydraulic station with cooling unit; flying shearing device for continuous cut and post-cutting for final length. Cooling stabilizes oil temperature in high-speed shifts.
Q6: Voltage and power?
A: AC380V or AC480V, 50/60Hz, 65kW installed for the structural CZU-based config; decoiler/manual options quoted separately.
Q7: Can C purlin replace channel steel?
A: Cold-bent C sections are thin-wall and high-strength; at equivalent performance they can save around 30% material versus traditional channel steel, which is a strong tender/commercial angle.
Q8: How do I get a quote?
A: Send C purlin drawing（web×flange×lip, thickness, yield, hourly/shift meter target, max length tolerance, voltage, decoiler capacity）. Wadjay configures stands, AMS brand, gearbox ratio, flying/post-cut, hydraulic cooling and returns lead time/price.
