Automatic production line for C-profiles
C purlin production line — decoiling, feeding, levelling, roll forming, cutting and collection of the finished profile.
Automatic C Purlin Production Line
The professional C purlin production line is designed for forming components from galvanized, black and hot-rolled steel sheet. The machine performs the full production cycle: decoiling, feeding, levelling, roll forming, cutting and collection of finished profiles.
The system is designed for producing profiles from material with a thickness of 1.5–2.0 mm and a yield strength of up to G345 MPa. The line operating speed is 0–15 m/min, and PLC control enables automatic monitoring of the length and quantity of produced components.
The machine combines a 3T decoiler, feeding and levelling section, 12 forming stations, hydraulic cutting, receiving table and PLC control with a touchscreen.
Line View, C Profile and Key Machine Modules
Complete C Purlin Line Workflow
The line performs production in a structured and repeatable manner. Coil material is fed onto the decoiler, then fed and straightened before passing through the forming roller section. After the required shape is achieved, the system measures the length and performs hydraulic cutting.
Coil Decoiling
The decoiler supports and unwinds the steel coil.
Feeding
The material is guided into the working section.
Levelling
Straightening rollers prepare the steel strip for forming.
Forming
12 roller stations give the profile its final C shape.
Cutting and Collection
Finished profiles are cut and placed on the receiving table.
Why Choose This C Purlin Production Line?
Complete Configuration — decoiler, feeding, levelling, forming, hydraulic cutting, PLC control and receiving tables.
Processing 1.5–2.0 mm Sheet — the line is suitable for galvanized, black and hot-rolled steel.
0–15 m/min Speed — efficient profile production while maintaining process control.
12 Forming Stations — stable, gradual shaping of the C profile.
Post-Forming Cutting — hydraulic cutting of the profile after the set length is reached.
Automatic Length Measurement — the encoder allows control of the length and quantity of workpieces.
PLC Control — the touchscreen enables quick input of production data.
Stable Construction — the 350 H-beam frame and centre side-plate arrangement provide machine rigidity.
Main Components of the Production Line
Manual Decoiler
The decoiler supports the steel coil and enables unwinding. The system capacity is 3 tonnes, the uncoiling width is 500 mm and the coil inner diameter is 450–550 mm.
Feeding and Levelling
The system straightens the steel strip before it enters the forming rollers. It is equipped with feeding, guiding and levelling rollers: 3 upper + 4 lower.
Main Forming Section
Roll forming takes place on 12 roller stations. The rollers are made of Cr15 steel after heat treatment and precision machining.
Cutting System
Hydraulic post-forming cutting ensures stability, precision and reduced scrap. Length measurement is performed automatically by an encoder.
Electrical Control
The PLC system with touchscreen controls the automation of forming, cutting and measurement. Includes a Delta inverter and Omron encoder.
Hydraulic Power Unit
The hydraulic power unit drives the cutting system. It includes an oil tank, pumps, hydraulic hoses, solenoid valves and an air-cooling system.
Where Is the C Purlin Line Suitable?
The C purlin line is designed for manufacturing structural, assembly and technical components from steel sheet. It is suitable for producing profiles used in lightweight steel structures, enclosures, support systems, industrial structures, racks, installation components and parts intended for further assembly.
Steel Structures — production of profiles for lightweight frames, brackets and load-bearing components.
Construction and Industrial Buildings — profiles for enclosures, auxiliary structures and installation components.
Technical Systems — installation, support, guide and structural components.
Serial Production — automatic length and quantity measurement supports repeatable production.
