One Line for C Channels, U Tracks and CU Purlins
In light steel fabrication, the bottleneck is rarely the rolling itself — it is the number of dedicated machines sitting idle between job changes. The Wadjay CU purlin roll forming machine is built so a single line covers C studs, U tracks, furring channels, omega sections and CU purlins, configured from the customer’s profile drawing rather than forced into a fixed die set.
In Wadjay’s Zhengzhou workshop, every CU line is assembled against the submitted cross-section: roller passes are sequenced on a 3D bend simulation, the 45# forged rollers are CNC-turned and hard-chrome plated, then the line runs a first-article coil before container loading. The operator checks flange squareness, web flatness, hole pitch and cut length on the actual profile — not a generic sample. That hands-on commissioning record is what separates a configured machine from a catalog guess.CU purlin roll forming machine
The line processes galvanized, PPGI, cold-rolled and black steel strip from 0.3–3mm (by profile), producing finished C/U sections continuously through decoiler → leveling → servo feed → optional hydraulic punch → roll forming → servo tracking cut → discharge table.

How the CU Line Actually Runs.CU purlin roll forming machine
The engineering value is in the sequence, not just the components.
- Decoiling with tension control — strip feeds without whipping or surface scratch; sensor warns before coil end.
- Leveling & guiding — multi-roller straightener removes coil set so the flange does not twist after forming.
- Servo metering — encoder-closed loop feeds exact length; acceleration/deceleration kept inside tolerance.
- Inline hydraulic punching — bolt holes, slots and marks are pierced before the section closes, so hole position stays locked relative to bend lines.
- Progressive cold forming — 10–20 roller stations bend the strip gradually. Gradual pass design controls springback and avoids edge wave on thin galvanized coil.
- Servo tracking cut — blade follows the moving profile and shears without stopping the line; Cr12MoV edge stays sharp through long runs.
- Recipe storage — each C/U size is saved as a PLC recipe: length, quantity, hole pitch, speed. Next order loads in seconds.

FAQs
Q1: Can it make both C and U on the same machine?
A: Yes. Within the roller envelope, C studs and U tracks are produced by spacer/recipe change; a different cross-family profile (e.g. omega) is confirmed by drawing.
Q2: What thickness and material?
A: Typically 0.3–3mm galvanized, PPGI, cold-rolled or black steel. Heavy-gauged structural purlin versions are quoted separately.
Q3: Do I need to change rollers for every size?
A: Not for sizes inside the configured range — infinite sizing via spacer and PLC recipe. A radically different profile may need dedicated rollers.
Q4: How accurate is the cutting and hole pitch?
A: Servo feed + encoder control; real tolerance is verified on your profile during first-article run, not assumed from a generic spec sheet.
Q5: What speed can I expect?
A: 15–60 m/min depending on profile depth, punch load and material. Light keel runs faster; punched structural C runs slower.
Q6: Which PLC brand?
A: Mitsubishi, Siemens, Delta or equivalent — selected by market and budget, with multilingual HMI.
Q7: Can it punch holes inline?
A: Yes. Hydraulic punch stations for web/flange holes, slots and logos, positioned by PLC before forming.
Q8: CE / ISO / warranty?
A: CE/ISO configurable; 12-month after-sales with spare parts and video support.
Q9: How do I get a quote?
A: Send profile DXF/CAD, material grade & thickness, coil width, hole drawing, daily output, voltage/Hz. Wadjay returns roller plan, line layout and price.
