The Z purlin cold roll forming machine stands as a cornerstone of efficiency in the metal construction industry. This specialized equipment transforms flat steel coils into high-strength Z-shaped purlins through a precise, continuous cold-forming process. For fabricators and builders, investing in a reliable machine is not just a purchase—it’s a commitment to project quality, timeline integrity, and structural safety. Our engineered solution is built to meet and exceed these demands.
Unmatched Production Characteristics of Our Z Purlin Machine
Our Z and CZ purlin roll forming machine is designed from the ground up for durability, stability, and superior output quality. We’ve integrated key features that address common pain points in metal forming.
-
Enhanced Firmness & Stability: The machine utilizes a reinforced station design and a gearbox transmission system. Unlike simpler chain-driven systems, the gearbox ensures synchronized, powerful, and stable rotation of all forming rolls, significantly reducing vibration and wear for consistent profile geometry. As noted by the Precision Metalforming Association, a stable drive system is critical for maintaining tolerances in high-speed forming.
-
Superior Cut Quality: We employ an after-cutting method. The formed purlin is first precisely measured and then cleanly cut to length after the final forming station. This guarantees that every cut end is perfectly smooth, square, and free of deformation, ensuring seamless joining and installation on the job site—a non-negotiable quality in structural applications.
-
Versatile Application: The Z purlins produced are widely used in steel structure buildings, including warehouses, industrial plants, commercial complexes, and agricultural buildings. They serve as essential horizontal members (purlins and girts) that support roof and wall cladding, transferring loads to the primary building frame.
Detailed Technical Specifications
This machine is built for robust, daily production. Here are the core specifications that define its capability:
-
Material Thickness: 1.5 – 3.0 mm (Ideal for a wide range of structural steel gauges).
-
Forming Speed: Up to 15 meters per minute (Excluding cutting and punching cycle time).
-
Roll Stations: 18 stations. This high number allows for a gradual, precise formation of the complex Z-profile, minimizing stress on the material and ensuring sharp, accurate angles.
-
Power Configuration: Main Motor Power: 15 KW; Hydraulic System Power: 5.5 KW.
-
Control & Drive: Control System: Panasonic PLC for reliable automation of length, quantity, and sequencing. Drive Mechanism: Chain-driven automatic feeding for consistent material advance.
-
Level of Automation: Available in Semi-Automatic and Fully Automatic configurations to suit different production volumes and labor requirements.
Why Choose This Cold Roll Forming Machine?
Selecting the right cold roll forming machine is critical. Our machine offers distinct competitive advantages that translate directly to your bottom line.
-
Precision Engineering for Perfect Purlins: The 18-station progression ensures each bend is formed with minimal springback, resulting in Z-purlins with consistent leg lengths, flange angles, and camber—meeting strict ASTM International standards for structural components.
-
Durability that Lowers TCO: The gearbox transmission and heavy-duty station construction mean less downtime for maintenance and repairs. This robust build quality extends the machine’s operational lifespan, providing a better return on investment.
-
Operational Efficiency: The PLC control system allows for quick setup changes, precise length control, and reduced material waste. Operators can store job parameters for repeat orders, slashing setup time and minimizing human error.
