Automatic C Z Purlin Roll Forming Machine — Interchangeable C/Z, Delta PLC, Hydraulic Cutting ±1mm (0.3–0.8mm Galvanized)
Why Choose an Automatic C Z Purlin Roll Forming Machine?
A automatic C Z purlin roll forming machine solves the core problem of steel-structure workshops: producing both C purlins (wall girts, studs, brackets) and Z purlins (roof purlins with overlapping laps) without buying two lines or swapping full roller sets by hand.
The Wadjay full-automatic CZ model uses an adjustable round-wheel design instead of full roller changeover — the operator sets length/quantity on the Delta PLC HMI, selects C or Z recipe, and the line forms galvanized strip continuously through feeding → leveling → roll forming → hydraulic cutting.
For light-gauge steel purlins (0.3–0.8mm galvanized), it runs 30–50 m/min with ±1mm cutting tolerance, backed by a 14mm cast-steel middle plate so the frame holds shape during continuous shifts.

How the C/Z Interchange Works
Traditional C-only or Z-only lines need roller-set swaps. This machine uses adjustable round wheels on the side-roll assemblies:
- C mode — flanges formed outward (Cee channel), used for wall girts, studs, brackets.
- Z mode — one flange side flipped by wheel position, giving overlapping Z section for roof purlins.
- PLC recipe — operator picks profile on HMI; roller gap/guide position adjusted mechanically via round-wheel screws, no full tear-down.
- Auto / Manual — batch runs in automatic length+quantity mode; manual mode for sample/test piece or maintenance.
Changeover time depends on whether it is round-wheel adjust (fast) or includes punch-die swap (longer) — don’t quote a fixed minute number without showing the demo video.
Production Flow
- Decoiling — 3T manual uncoiler, galvanized coil ID 470–530mm.
- Entry guide — strip centered before first roller to avoid camber drift.
- Roll forming（10 stands） — Cr12 rollers progressively bend web/flange/lip; 45# chrome shaft reduces friction.
- Delta PLC control — set target length, batch quantity, production count.
- Hydraulic cutting — guillotine cut at ±1mm; no blade change for C/Z within same width range.
- Run-out — 3m receiving table, manual stack.
Application Scenarios
- Steel-structure workshops / warehouses — C wall girts, Z roof purlins from one line
- Light steel villas / interior framing — C stud, furring channel, main channel when configured thin-gauge
- Commercial buildings — exhibition halls, gyms, retail sheds
- Agricultural sheds — farm equipment storage, livestock barns
- Solar mounting（light duty） — C/U support channels
- Job-shop fabricators — mixed C/Z orders, low changeover labor
Why Wadjay Full-Auto CZ Purlin Line
- C/Z one line — round-wheel interchange, no full roller swap for standard sizes
- 14mm cast-steel middle plate — frame stability on thin-strip high-speed runs
- Cr12 rollers + chrome shaft — wear resistance for galvanized coil
- Delta PLC HMI — length/quantity presets, EN/ZH/ES/RU interface for export crews
- Hydraulic cut ±1mm — clean end for on-site bolting
- Auto + manual mode — batch production and sample testing
- ISO manufacturing — configurable CE/voltage/color for destination market
FAQs
Q1: Can it make C and Z without changing rollers?
A: For standard size ranges, yes — adjustable round-wheel design shifts flange position without full roller-set swap. If punch holes or lip geometry differ greatly, die/guide adjustment may be needed; confirm by profile drawing.
Q2: What thickness can it run?
A: Standard light-gauge config 0.3–0.8mm galvanized. For 1.0–3.2mm structural purlin, use the CZU/heavy platform with more stations, hydraulic punch and servo adjust — quote separately.
Q3: How fast and how accurate?
A: 30–50 m/min line speed, ±1mm cutting tolerance under standard condition. Real output depends on thickness, length mix, hole pattern and decoiler reload time — not catalogue speed alone.
Q4: What PLC and languages?
A: Delta PLC + touch screen, auto/manual modes, English/Chinese/Spanish/Russian HMI. Other languages configurable.
Q5: Hydraulic or flying cut?
A: Light-gauge version uses hydraulic stop-cut guillotine ±1mm. High-speed structural version can add flying shear — by configuration.
Q6: Does it punch holes?
A: Light-gauge base page does not include inline punching by default. Web/flange punching (3+2 stations) is available on CZU structural config — send hole drawing.
Q7: CE / ISO / warranty?
A: ISO standard; CE configurable. Warranty/lead time confirmed per order scope — not fixed on the product page.
Q8: How do I get a real quote?
A: Send C/Z profile drawings (web×flange×lip), thickness, yield, coil width, hole positions, length range, daily meter target, voltage/Hz, destination. Wadjay returns config + price.
