CZ Roll Forming Machine 4 Steel Grades Reliable Performance

On a CZ purlin production line, a cz roll forming machine must handle steel coils that are not always the same. Some orders use Q235, others use Q345. If the equipment cannot cover these materials, the factory's order range will be limited. The machine's material adaptability directly determines what types of orders the factory can take.
This cz roll forming machine covers four steel grades from Q195 to Q355 in its current configuration. Parameters such as speed, voltage, transmission method, and C/Z profile dimensions can be customized according to customer needs. Different material grades place different demands on the equipment.
CZ purlins are used in steel structure workshops, logistics warehouses, solar mounting, agricultural facilities, and other scenarios. These projects all use CZ purlins, but different projects have different load requirements and different choices of material yield strength. The specific grade to use depends on project design, section size, plate thickness, and load conditions.
A fully automated CZ purlin roll forming machine needs to cover these material ranges to handle different orders. The current machine covers four grades from Q195 to Q355. If a project requires other material grades, the equipment configuration needs to be confirmed based on the specific material requirements.

The parameter table for this cz roll forming machine provides the material range and overall specifications of the machine in its current configuration.
| Parameter | Value |
|---|---|
| Materials processed | Galvanized coil / low carbon steel coil |
| Material yield strength | Q195 / Q235 / Q345 / Q355 |
| Material thickness | 1.0 to 3.0 mm |
| C purlin width | 80 to 300 mm |
| Z purlin width | 120 to 300 mm |
| Flange height | 30 to 100 mm |
| Lip length | 10 to 20 mm |
| Power supply | 380V 50Hz 3 phase (customizable) |
| Hydraulic station power | 11 kW |
| Decoiler loading capacity | 5 tons maximum |
| Coil inner diameter | 450 to 550 mm |
| Complete line dimensions | about 22m x 2.0m x 2.0m |
| Complete line weight | about 15 tons |
| Length tolerance | 3000mm plus or minus 1.0mm |
The parameters above are for the current configuration. As a cz interchangeable purlin machine, this equipment supports both C and Z sections. Speed, voltage, transmission method, and C/Z profile dimensions can be customized according to customer needs. The material yield strength range is based on the current configuration. Other material grades need to be confirmed according to specific project requirements.
On a cz roll forming machine, different yield strength materials have different characteristics in CZ purlin production.
Q195 and Q235 are low carbon steel with lower yield strength, good plasticity, and easy forming.
Q345 and Q355 are low alloy high strength steel with higher yield strength.
The specific grade to use depends on project design, section size, plate thickness, and load conditions.
High yield strength material has stronger load capacity at the same section and thickness, or can reduce plate thickness under the same load requirement.
Material strength is not the only deciding factor. Section shape, plate thickness, and connection method also affect purlin performance.
The current machine covers four steel grades from Q195 to Q355. This means the factory can take orders using these material grades. If a customer has special material requirements, the equipment configuration needs to be confirmed based on the specific material requirements.


Cutting quality on a cz roll forming machine has a direct impact on the final use of CZ purlins.
CZ purlins need connection holes and cut end faces during installation. If the cut end face has burrs or deformation, installation may require secondary grinding or trimming. This adds on site workload.
Cr12MoV tooling with hydraulic shearing is the cutting configuration of the current machine. Cr12MoV is a cold work die steel. After quenching treatment, it has higher hardness and better wear resistance. Hydraulic shearing moves smoothly during cutting, and the cut end face is relatively flat. But this does not mean all materials at all thicknesses can guarantee a completely smooth cut without burrs. Actual cut quality also depends on material thickness, material strength, and tool wear. A relatively flat cut helps on site installation and reduces subsequent trimming needs.


This cz roll forming machine offers several practical values in material adaptability and customization flexibility.
Covers four steel grades from Q195 to Q355, giving the factory more flexibility in accepting orders with different material grades.
Speed, voltage, transmission method, and C/Z profile dimensions can be customized to match different project requirements.
The machine supports production of both C and Z sections, giving factories more flexibility in product type.
Cr12MoV tooling with hydraulic shearing helps achieve a relatively flat cut and reduces subsequent trimming needs.
Together, these advantages mean that when a factory faces orders with different materials, it has more options for handling material changes and specification changes. Material coverage and customization flexibility directly affect the manufacturer's adaptability to different order types.




On a CZ purlin production line, the steel coils customers send are not always the same.
The value of a cz roll forming machine is not that it can process one specific material, but that it can cover multiple material grades and reduce production limits caused by material grade changes. Parameters such as speed, voltage, transmission method, and profile dimensions can be customized according to customer needs. This adaptability gives factories more confidence when taking orders.
