Automatic C/Z Purlin Roll Forming Machine for Steel Structures

The C/Z Purlin Roll Forming Machine is an integrated production line designed for continuous manufacturing of C-shaped and Z-shaped steel purlins. By combining automatic coil feeding, leveling, CNC punching, cold roll forming, flying cutting, and finished-product stacking, the system provides an efficient solution for structural steel fabrication.

Its quick-change design allows manufacturers to switch between C and Z profiles without replacing the forming rollers, while adjustable tooling supports different web heights and flange dimensions.

Fast C and Z Profile Conversion

One of the main advantages of the production line is its C/Z profile changeover system. Depending on the machine configuration, the roller mechanism can be adjusted manually or through a motorized PLC-controlled system.

Profile conversion can generally be completed within 5–15 minutes, allowing manufacturers to produce different purlin profiles on the same line while reducing setup downtime.

The adjustable roller stands also allow the machine to accommodate different C/Z web widths and flange sizes according to production requirements.

Continuous High-Speed Purlin Production

The forming line is designed for continuous production at speeds of up to 20–60 m/min. A servo tracking flying shear system cuts finished profiles to the required length while allowing the forming process to continue without stopping.

This configuration helps maintain production continuity and is particularly suitable for steel fabrication operations handling larger production volumes.

Complete Automated Production Line

The machine integrates several processing stages into one coordinated system:

1. Hydraulic Uncoiler with Loading Car
   Available in 3T and 5T capacities for stable feeding of steel strip coils.

2. Multi-Roll Precision Leveler
   Straightens the incoming material and helps remove coil set and internal stress before punching and forming.

3. CNC Servo Punching Unit
   A multi-station punching system creates web and flange holes according to programmed production patterns.

4. C/Z Cold Roll Forming Mill
   The main forming section uses 20 forming stations with adjustable roller stands for profile shaping and size adjustment.

5. Servo Tracking Flying Shear
   The hydraulic flying cut-off system tracks the moving profile and cuts it to the programmed length without interrupting the forming process.

6. Automatic Run-Out Stacker
   Finished C and Z purlins are collected and arranged automatically for easier handling and subsequent transportation.

Heavy-Duty Roll Forming Tooling

The forming rollers are manufactured from GCr15 or Cr12MoV alloy steel and undergo hardening and vacuum heat treatment. This tooling configuration is intended to maintain forming accuracy and provide resistance to wear during extended production.

The multi-station forming structure gradually shapes the steel strip, helping achieve consistent C and Z profiles throughout the production process.

Technical Specifications

Applications in Steel Construction

The C/Z purlin production line is designed for manufacturing structural profiles used across a variety of steel construction projects.

Industrial Steel Buildings

The machine can produce C and Z purlins for roof structures and wall girts used in industrial plants and commercial steel buildings.

Pre-Engineered Buildings

C/Z profiles are commonly incorporated into pre-engineered building systems as structural channels and supporting members. The machine's profile flexibility allows manufacturers to produce different dimensions according to project specifications.

Warehouses and Logistics Facilities

Large-span warehouses and logistics buildings often require standardized structural steel profiles. Continuous roll forming and automated punching make this production line suitable for high-volume fabrication requirements.

Flexible C/Z Purlin Manufacturing

The combination of adjustable forming tooling, CNC punching, and automated profile switching enables manufacturers to produce multiple C and Z purlin specifications on one production line.

The system can process steel materials from 1.0 to 3.0 mm thick, with customizable strip widths between 800 and 1250 mm. Higher-strength steel options can also be accommodated according to the machine configuration.

Installation, Commissioning and Training

Technical support is available for international customers, including on-site installation, machine commissioning, and operator training. Technical assistance can also continue after installation to support machine operation and production.

For manufacturers seeking a flexible solution for structural steel profile production, this automated C/Z purlin roll forming line combines rapid profile changeover, continuous forming, CNC punching, flying cutting, and automatic stacking in a single production system.
