Core automatic cz purlin roll forming machine Features
Optimized for Z Profile Lap Joint Design
This machine is specially engineered for Z purlin geometry. The unique overlapping flange design allows purlins to connect end-to-end directly without additional connecting plates, simplifying on-site installation and enhancing the overall stability of roof structures.
Progressive Multi-Pass Forming & Springback Compensation
Steel strips are bent gradually through multiple roller passes to relieve internal stress and minimize springback. Chrome-plated forming rollers guarantee scratch-free surface, excellent straightness and uniform cross-section. The finished Z purlins maintain stable mechanical strength to resist wind and snow loads.
Servo Feeding with Inline Hydraulic Punching
The servo feeding system synchronizes with hydraulic punching, delivering precise and repeatable hole positions. Flying shear cuts profiles to preset lengths without line stop. Customers can customize round holes or slotted holes according to their installation drawings.
High-Rigidity Welded Machine Base
Thick plate welded frame offers strong vibration resistance during long-hour continuous operation. Precision gearbox transmission ensures stable, low-noise running. Famous brand electrical components reduce failure probability and lower routine maintenance costs.
Application Scope
Manufactured from durable cold-formed steel, these CZ purlins serve as critical structural secondary members that transfer roof and wall loads to the main frame. Their interchangeable production enables fabricators to meet diverse engineering specifications within a single production line.
They are widely selected for pitched roof systems of prefabricated steel buildings, including manufacturing plants, distribution warehouses and cold storage facilities. Z purlins are preferred for long-span sloped roofs thanks to their lap-joint capability, while C purlins are commonly deployed for wall framing and shorter-span roof applications.
Within renewable energy construction, these profiles are widely adopted for solar mounting frameworks, including ground PV stations, rooftop solar arrays and large solar carport canopies. They are also suitable for agricultural solar greenhouses, platform mezzanine supports and temporary modular steel structures.
With excellent corrosion resistance when using galvanized substrates, these purlins withstand harsh outdoor environments, resisting wind pressure and snow accumulation. They are versatile for both permanent commercial construction and modular, fast-track building projects.
FAQ
What is the main advantage of an automatic CZ purlin machine?
It can produce both C purlin and Z purlin on one line with automatic switching. Factories no longer need separate machines for C and Z profiles, saving workshop space and equipment purchasing cost.
What sizes of C and Z purlins can it produce?
The web height ranges from 80mm to 300mm, material thickness 1.2mm to 3.0mm. Custom sizes are available based on your engineering drawings.
Can the machine punch holes on Z purlins during forming?
Yes. It is equipped with inline hydraulic punching station. Servo feeding controls punching position tolerance within ±0.5mm. Custom hole spacing and hole types are available for bolt connection.
Can the machine process galvanized steel coils for outdoor solar projects?
Yes. Polished chrome rollers protect galvanized coating from scratches during cold forming. Finished Z purlins retain good anti-corrosion performance for long-term outdoor use.
What warranty and after-sales services are available?
We provide 12-month whole machine warranty and lifelong online technical support. Non-human damaged spare parts are free within warranty. Overseas installation, commissioning and operator training are available with 24-hour online support.
