Profile Information
CZ purlins are used for steel structure roof and wall support. Their adjustable C and Z shapes provide strong load capacity and multiple size options.
CZ purlins commonly use 1.5-3.0mm galvanized steel or black steel coils for high strength, corrosion resistance, and stable structural performance in construction projects.
How Does The Roll Forming Machine Work?
Machine Details
Steel Coil Decoiler
Steel coil decoiler is used to unwind metal coils smoothly for feeding into roll forming, cutting, or punching processes.
Manual decoiler is a basic and economical option, while motorized and hydraulic decoilers are also available for higher efficiency and automation:
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 5/7/10 Ton | Expanding Range | 460-50mm |
Leveler
The leveler removes coil stress and improves sheet flatness before forming, helping maintain accurate punching position and stable CZ purlin dimensions.
Servo Feeder & Hydraulic Punching Machine
The servo feeder accurately controls feeding length before punching, ensuring hole position consistency for different purlin sizes.
The hydraulic punching machine performs hole punching, slot punching, and customized operations according to project drawings. Compared with manual processing, it improves production efficiency, reduces positioning errors, and maintains cleaner punching quality for steel structure installation.
Roll Forming Machine
The cast-iron stand roll forming machine with chain transmission provides stable forming for different CZ purlin sizes.
It supports punching production, multiple specifications, and customized profile requirements with reliable long-term operation performance.
| Speed | 20m/min | Forming Station | 18 Stands |
| Motor Power | 7.5Kw | Shaft Diameter | 76mm, solid |
| Driving System | Chain | Roller Material | Gcr15,HRC58-62° |
| Frame Structure | Wall panel | Shaft Material | 40Cr heat treatment |
CZ Shape Changing
The machine changes between C and Z purlin production through manual roller adjustment and profile position conversion for flexible manufacturing.
Hydraulic Cut
After roll forming, the hydraulic cutting unit performs stop-to-cut operation to prevent profile movement during cutting and maintain accurate cutting length.
The universal cutting system uses one cutting mold for different CZ purlin sizes without changing blades, improving production convenience. For customers requiring higher production speed, customized non-stop flying cutting solutions are also available.
| Power Type | Hydraulic cut | When Cutting | Forming stops |
| Blade Material | Cr12MoV | Length Tolerance | ≤±1mm |
Safety Designs
Chain covers are installed to protect operators and extend chain service life. Full-machine mesh covers (slidable) provide visibility with safety. Flip-type covers ensure convenient access with enhanced protection.
Safety signs are applied to continuously alert operators.
PLC Control Cabinet & Encoder
In a cold roll forming line, the encoder works with the PLC to provide real-time feedback on material position and speed, ensuring precise feed, synchronized forming, and accurate length control for cutting and punching.
Production speed, product length, and quantity can be set on the control cabinet. The display language can be customized according to customer requirements.
Other Customization Details
The machine comes standard with a blue main color and orange accents. Other colors can be customized free of charge.
The default metal nameplate is Goalon, which can also be customized at no additional cost.
Basic Services
Professional Packing
Machines are packed in plastic film and labeled for easy identification and assembly, and secured inside the container with steel cables.
Installation Guide
Free customized manuals, operationvideos, installationvideos, and remote video supportare provided.
The standard configuration operates at 15–20 m/min. Higher-end configurations can reach 30–40 m/min, and even higher speeds can be customized according to specific production requirements.
Lead times range from 30-40 days post-order, varying by customization level and supplier location. We typically require 35 days for standard machines.
Yes. The universal hydraulic cutting system allows different CZ purlin sizes to share one cutting mold, reducing adjustment time and tooling cost.
Yes. We are a professional manufacturer that produces both standard market profiles and customized profiles. We can also sign an agreement to ensure that your drawing will not be shared with other parties.
There is no need to worry. Our machines are designed for easy installation and operation.
Before shipment, we will finish the main assembly and testing in our factory. When the machine arrives, you only need to place it in position, connect the power supply, and it can start working.
We will also provide:
detailed installation and operation manuals
machine layout drawings
wiring diagrams
online technical support (video call / photos / videos)
If needed, we can also arrange an engineer to come to your factory to help with installation and training. Many of our customers complete installation smoothly with our online guidance.
It depends on customer requirements. Edge folding improves safety by eliminating sharp edges and enhances installation quality, especially for manual handling and roofing applications.
