Fully Automatic Metal Steel Hat Profile Purlin Production Line
Automatic Size Change • Hydraulic Punching • Hydraulic Cutting • PLC Control
The Omega Hat Purlin Roll Forming Machine is a fully automatic production line designed for manufacturing high-strength metal Hat Purlins and Top Hat Purlins in batches.
The production line integrates automatic coil feeding, leveling, roll forming, hydraulic punching, hydraulic shearing and PLC control into one continuous production system.
With automatic profile size adjustment, the machine can produce different Hat Purlin sizes from approximately 100 mm to 300 mm, depending on the customer's profile requirements.
CAD drawing input and batch programming allow operators to set production length, quantity and other production requirements through the control system.
The PLC-controlled system supports automatic profile size adjustment within the designed range, reducing manual adjustment and production downtime.
Operators can set production length, quantity and batch requirements through the control system for continuous automated production.
The hydraulic punching system provides precise hole positioning according to the required purlin design.
Automatic length measurement and hydraulic shearing provide accurate cutting according to programmed production requirements.
CAD drawing input can be integrated into the production control process, making batch programming more convenient.
The complete production line is controlled through an intelligent PLC system for coordinated forming, punching and cutting operations.
The machine is designed for manufacturing Omega / Hat profile purlins with adjustable profile dimensions according to the customer's requirements.
Automatic steel coil feeding
Straighten and stabilize the strip
Guide rollers position the material
Gradually form the Hat profile
Hydraulic hole punching
Automatic length cutting
The leveling section is designed to straighten the steel strip before it enters the roll forming process, helping improve forming accuracy and production stability.
A properly leveled strip provides a stable starting point for the subsequent roll forming process.
The hydraulic punching unit is designed to create required holes accurately according to the purlin drawing and production program.
Multiple forming stations gradually shape the steel strip into the required Omega / Hat Purlin profile while maintaining stable and continuous production.
The forming section uses multiple forming stations to gradually shape the steel strip into the required profile.
Rollers are manufactured from Cr12 material with CNC processing and heat treatment to improve durability.
The forming shafts use solid construction with 40Cr material and precision machining.
Profile sizes can be changed automatically through the PLC system according to the programmed production requirements.

The hydraulic cutting system automatically measures the required length through an encoder and cuts the formed purlin according to the programmed production requirements.
The control system coordinates the complete production process, including feeding, roll forming, punching, cutting and automatic size changes.
Set production quantity and length according to the required order.
CAD drawing input supports convenient profile and batch programming.
PLC control allows automatic profile size changes according to the configured production range.
English is supported, with multi-language control options available according to customer requirements.
