C Z Purlin Cold Roll Forming Machine with Automatic Hydraulic and Quick Change 1.0-3.0 mm for both c and z purlin

Reliable Hydraulic CZ Purlin Rolling Machine for 80 to 300 mm Profiles

A hydraulic cz purlin rolling machine is a cold roll forming equipment used to produce purlins for steel structure buildings. Purlins are horizontal members that support roof or wall panels. This machine processes steel coils into specific cross‑sectional profiles through a continuous forming process.

In steel buildings, purlins are secondary structural members that transfer loads to the main frame. The hydraulic cz purlin rolling machine turns coils into these key components.

Core Advantages

One Machine for Two Profiles

The machine supports both C and Z section production. Section changeover is simplified through the touchscreen interface, reducing downtime and improving equipment utilization. One unit handles two profile types, which helps keep production flexible.

PLC Control and Simplified Operation

The equipment includes a PLC control system and touchscreen interface. The control logic reduces operator workload, and basic parameter setup can be learned quickly. Line monitoring requires minimal staffing.

Punching and Cutting Integration

The machine integrates punching and cutting functions. Hole positions and cut lengths are set via the control system, which helps maintain consistent part quality and reduces secondary processing steps.

Material Compatibility

The equipment processes galvanized and low‑carbon steel coils, with yield strengths from Q195 to Q355. This material flexibility supports various project requirements.

Main Application Scenarios

The C and Z purlins produced by this hydraulic cz purlin rolling machine are used in:

• Industrial factories – roof and wall purlins

• Logistics warehouses – roof systems and rack supports

• Agricultural greenhouses – frame structures

• Commercial buildings – secondary roof and wall structures

These applications cover common light to medium steel structure projects.

What Products Does a Purlin Machine Produce? What Is the Difference Between C and Z?

C Purlin and Z Purlin – Basic Profiles

A purlin machine produces two main profile types: C purlin and Z purlin.

C purlin has a C‑shaped section with the web and flange at 90 degrees. It is often used for wall girts and floor beams.

Z purlin has a Z‑shaped section, with the web and flange at an angle (typically 60‑75 degrees). It can be lapped at supports, making it suitable for long‑span roof applications.

Key Differences

• Section shape: C has a straight web and parallel flanges; Z has an angled web.

• Connection method: Z sections allow overlapping at supports for continuous spans; C sections are typically used as simple spans.

• Typical use: C is common for walls and floors; Z is common for long‑span roofs.

How Does a Purlin Machine Work?

The production line sequence: decoiling → feeding/leveling → punching → roll forming → cutting → stacking

• Decoiler: Holds the steel coil and releases it under controlled tension.

• Leveling unit: Removes coil curvature and stress, producing a flat strip.

• Punching station: Creates holes in the strip before or during forming.

• Roll forming section: The strip passes through multiple roller stands, each gradually bending the material until the final C or Z section is achieved.

• Hydraulic shear: Cuts the continuous formed purlin to the required length.

• Stacking table: Collects finished purlins automatically.

The line operates with coordinated speed control to maintain steady material flow.
