Main Product Content

1. Product Introduction

The Z Purlin Cold Roll Forming Machine is a dedicated continuous cold bending production line independently developed for producing Z-shaped steel purlins, a core secondary structural component of large-span steel construction projects.

This Z Purlin Cold Roll Forming Machine integrates uncoiling, leveling, continuous roll forming, hydraulic punching, fixed-length cutting and finished product collection into one fully automated workflow. Flat galvanized steel coil, color coated steel or carbon steel strip can be processed into standard Z purlin profiles in a single pass without secondary processing.

Equipped with a touch screen PLC control system, the Z Purlin Cold Roll Forming Machine allows quick switching between different Z purlin specifications without replacing heavy forming molds, drastically cutting production downtime and labor costs for steel component manufacturers. Stable operation, ultra-precise molding and long service life make this Z Purlin Cold Roll Forming Machine the optimal processing equipment for steel structure factories worldwide.

2. Complete Working Process of Z Purlin Cold Roll Forming Machine

1. Uncoiling: Passive uncoiler holds raw steel coil for stable material feeding
2. Leveling Unit: Eliminates strip warpage to guarantee flat raw material
3. Feeding & Guiding Device: Positions steel strip accurately into forming tracks
4. Multi-Stage Cold Roll Forming: Gradual bending by alloy rollers to form Z purlin shape
5. Hydraulic Punching Station: Punches installation holes on purlin flanges as customized drawings
6. Servo Hydraulic Cutting: Fixed-length cutting with clean, burr-free section ends
7. Finished Product Stacking: Automatic collection of finished Z purlins for packaging

3. Core Superiorities of Z Purlin Cold Roll Forming Machine

Heavy-Duty Welded Machine Base

The frame of the Z Purlin Cold Roll Forming Machine adopts thickened H-beam integral welding, with stress relief annealing treatment. No permanent deformation occurs under long-term heavy-load operation, maintaining consistent forming precision for decades.

Wear-Resistant Forming Roller Group

All forming rollers of the Z Purlin Cold Roll Forming Machine are manufactured from 45# high carbon steel, quenched and hard chrome plated. The smooth roller surface avoids scratches on finished Z purlins, while multi-pass gradual bending prevents material cracking and internal stress distortion.

Intelligent PLC Touch Screen Control Cabinet

Every Z Purlin Cold Roll Forming Machine is fitted with an independent PLC control cabinet. Operators can set target purlin length, hole spacing, production batch count and line speed directly on the touch panel. Built-in fault self-diagnosis, automatic counting and emergency stop protection improve production safety and efficiency. All electrical components use internationally famous brands for low failure rates.

Integrated Hydraulic Punching & Cutting System

The hydraulic station matched with the Z Purlin Cold Roll Forming Machine delivers powerful, fast-response pressure for punching and cutting. Thick-wall hydraulic cylinders and imported sealing accessories eliminate oil leakage, ensuring neat cuts without distorting the Z purlin profile.

Wide Specification Compatibility

By adjusting roller spacing and guiding positions, one Z Purlin Cold Roll Forming Machine can produce multiple common Z purlin sizes for roof and wall structures. It supports raw material thickness from 1.0mm to 3.5mm, compatible with galvanized steel, prepainted color steel and plain carbon steel. Customized forming ranges are available upon client request.

4. Application of Z Purlins Produced by Z Purlin Cold Roll Forming Machine

Finished Z purlins manufactured from this Z Purlin Cold Roll Forming Machine serve as load-bearing secondary members in:

• Large steel structure factory workshops
• Logistics storage warehouses and distribution centers
• Agricultural greenhouses, livestock breeding sheds
• Stadiums, exhibition halls and public large-span buildings
• Light steel villas, carports and temporary container buildings

Z purlins feature superior flexural strength and spanning performance compared to C purlins, making them the top choice for long-span roofing engineering.
