Heavy-Duty Design

Reinforced rollers and larger shaft diameter provide stable forming performance for large-size and heavy-gauge purlins.

C/Z Automatic Change

PLC-controlled C and Z section changing allows flexible production of different purlin profiles without replacing the complete forming line.

Servo Motor Drive

Servo motor drive provides smooth operation, high positioning accuracy, fast response and stable performance under varying production loads.

Hydraulic Punching

Integrated hydraulic punching units process required holes before roll forming, helping maintain accurate hole shapes and reduce profile deformation.

Large-Size Purlin Forming

The machine is designed with enhanced roller thickness and shaft diameter for producing large and heavy-duty C/Z purlins.

• Standard width: 100–400 mm
• Material thickness: 1.5–4.0 mm
• Special sizes can be customized
• Suitable for C and Z purlin production
• Maximum purlin size: up to 400 mm

Machine Specifications

5T Manual Decoiler

The production line can be supplied with a 5-ton decoiler for continuous coil feeding.

• Coil capacity: 5 tons
• Coil inner diameter: 450–550 mm
• Maximum feeding width: 500 mm
• Welded steel plate and profile-bar structure
• Hydraulic drive configuration described in the supplied specification

Automatic Feeding & Leveling Device

The feeding and leveling system helps straighten the steel strip before it enters the roll forming section, improving feeding stability and forming accuracy.

• Automatic feeding-width adjustment by button
• 3 upper + 4 lower leveling rollers
• Roller diameter: 75 mm
• Roller material: Cr15
• Automatic feeding-width adjustment

Large-Diameter Shafts & Rollers

The heavy-duty forming system uses reinforced rollers and large solid shafts to provide stable forming performance for thicker and larger purlin profiles.

• Φ90 mm solid shafts
• 40Cr shaft material
• Cr12 roller material
• Rollers heat treated to HRC 58–60
• Heavy-duty 1.5-inch chain transmission
• Servo motor drive

Accurate Hole Punching Before Forming

The hydraulic punching system is integrated into the production line for punching required holes before the roll forming process. This helps maintain accurate hole shapes and reduces deformation caused by forming.

• Station 1: Bottom center hole punching
• Station 2: Bottom double-side hole punching
• Hydraulic punching system
• Designed for continuous automated production

Automatic Length Measurement

The hydraulic post-cutting system works with automatic encoder length measurement to cut C/Z purlins according to the programmed production requirements.

• Hydraulic post cutting
• GCr12 / Cr12MoV cutting blade
• Quenched blade treatment
• Automatic encoder length measurement
• Reference length tolerance: 3000 mm ± 1.0 mm
• Manual cutter adjustment for different C/Z purlin sizes

The PLC-based control system allows operators to set production orders, product length and quantity through the touchscreen interface. C and Z section changing is controlled by PLC.

• Delta PLC
