Metal Purlin Roll Forming Machine — High-Efficiency M Purlin Production Line with AMS Control & Flying Shear
Why Choose a Metal Purlin Roll Forming Machine?
A metal purlin roll forming machine is the production line that turns galvanized or cold-rolled steel coil into finished M-shaped steel purlins — one of the most widely used purlins and wall beams in modern steel structure construction . M-shaped steel can be combined into lightweight roof trusses and brackets, and is also used for columns, beams, and arms in light machinery manufacturing .
The Wadjay M purlin roll forming machine (SKU 2.97) is engineered for high-efficiency M-section purlin production. It integrates AMS Controls system, hydraulic station with cooling unit, flying shearing device, decoiler, and gearbox transmission into a single synchronized line . With material thickness of 0.3–0.8mm, a 70mm solid shaft, and 45# steel rollers polished and chrome coated to HRC55–60°, the machine delivers consistent, high-precision M-profile purlins at industrial volumes.
💡 The most valuable selling point isn’t just automation — it’s material efficiency. M-shaped steel is thin-walled, lightweight, and offers superior cross-sectional performance with high strength. Compared with traditional channel steel, the same structural strength can save 30% of raw material . For steel structure workshops and engineering projects, that directly reduces both material cost and building dead load.

How the M Purlin Production Line Works
The Wadjay metal purlin roll forming machine follows a fully integrated cold roll forming cycle :
- Uncoiling — 3-ton manual decoiler (provided free) holds the steel strip; standard distance to the host is 3 meters
- Feeding & Leveling — 1 row of feeding rollers flattens the strip and guides it into the roll forming host
- Roll Forming (Molding Core) — the host progressively bends the strip into the M-shaped cross-section through multiple stations driven by an 8# cycloid reducer and gearbox transmission
- Hydraulic System & Automatic Control — AMS Controls system with PLC frequency control and touch screen orchestrates length, quantity, and production parameters
- Step Formed Mechanism — the step-forming process progressively shapes the M-section profile with precision
- Automatic Shearing (Flying Shear) — flying shearing device executes continuous cut without stopping the line
- Products Receiving Tables — finished M purlins are collected neatly, ready for packaging or direct use
The entire workflow is automated: decoiler → molding core → hydraulic system → automatic control → step formed mechanism → automatic shearing → products receiving tables .
Application Scenarios
M-shaped steel produced by the metal purlin roll forming machine serves a broad range of structural applications :
- 🏭 Steel structure workshops & industrial buildings — roof purlins, wall beams, main structural framing
- 🏗️ Steel structure engineering — commonly used construction steel for industrial and commercial buildings
- 🔧 Lightweight roof trusses & brackets — combined M-section members for roof systems
- ⚙️ Light machinery manufacturing — columns, beams, and arms in light machinery production
- 📐 Wall beam applications — M-shaped steel as a widely used wall beam in steel construction
Because M-shaped steel is thin-walled, lightweight, and offers excellent cross-sectional performance with high strength, it has become a commonly used construction steel in steel structure projects worldwide . Compared to traditional channel steel, the 30% material saving directly reduces both raw material cost and overall building dead load.
💪 Why Wadjay’s Metal Purlin Roll Forming Machine Stands Out
- 3 highly efficient modules — AMS Controls system + Hydraulic station & cooling unit + Flying shearing device maximize production output per shift
- Premium drivetrain — 8# cycloid reducer (high grade) + gearbox transmission delivers stable torque and smooth forming
- Industrial-grade rollers — 45# steel, polished, chrome coated to HRC55–60° for extended service life and consistent profile accuracy
- 70mm solid shaft — high-rigidity shaft prevents deflection during continuous high-volume forming
- AMS Controls + PLC touch screen — reliable, industry-proven automation platform with intuitive operation
- Flying shear device — continuous cutting without stopping the line, maximizing throughput
- Free 3-ton decoiler — included with every machine, reducing initial capital expenditure
- Flexible profile production — roll forming host can produce light keels and M-section purlins per customer’s request
- 30% material saving — M-shaped steel vs traditional channel steel at equivalent strength
- Proven export product — Wadjay M purlin machines serve global steel structure markets
Frequently Asked Questions
Q1: What material thickness can the metal purlin roll forming machine process?
A: The standard configuration processes steel strip from 0.3 to 0.8mm thick . The machine is designed for galvanized and cold-rolled steel coils used in steel structure purlin manufacturing.
Q2: Is the decoiler really free?
A: Yes. Every metal purlin roll forming machine ships with a 3-ton manual decoiler at no additional cost . The decoiler is normally positioned 3 meters from the main machine for optimal strip feed .
Q3: How precise is the cutting?
A: The machine uses hydraulic cutting after roll forming, paired with a flying shearing device . The PLC frequency control system with touch screen ensures accurate length control for batch production .
Q4: What are the roller and shaft specifications?
A: The rollers are made of 45# steel, polished and chrome coated to HRC55–60° for wear resistance and long service life. The main shaft is a 70mm solid shaft machined from high-grade material for rigidity under continuous forming loads .
Q5: What is the transmission and reduction system?
A: The machine uses gearbox transmission driven by an 8# cycloid reducer (high grade) — a proven combination for stable torque transfer and smooth, vibration-free purlin forming .
Q6: Can the machine produce profiles other than M-shaped purlins?
A: The roll forming host can be configured to produce light keels and M-section purlins according to customer requirements . For fully interchangeable C/Z/U profiles, we recommend the C Z U Light Keel Stud Purlin Machine.
Q7: What is the main workflow of the machine?
A: The complete workflow is: Uncoiler → Molding core → Hydraulic System → Automatic Control system → Step Formed Mechanism → Automatic Shearing Mechanism → Products Receiving Tables .
Q8: What is the control system?
A: The machine is equipped with a PLC Frequency Control System with touch screen and AMS Controls system — providing intuitive operation for length setting, quantity programming, and production monitoring .
