Technical Deep Dive: Materials, Craftsmanship, and Performance
The reliability of a steel roll forming machine is determined by the quality of its components. We exemplify expertise in roll forming machine & die manufacturing by adhering to the highest standards.
Premium Material Selection
Rollers and cutting dies are forged from high-grade GCr15 / Cr12MoV bearing steel. This material is chosen for its exceptional hardness, wear resistance, and ability to hold a precise profile over millions of cycles, ensuring a long service life.
Advanced Manufacturing Craftsmanship
Our rollers undergo a multi-stage process: forging, rough CNC machining, rigorous heat treatment (quenching to HRC 58-62), followed by precision CNC grinding to achieve micron-level accuracy. The final chrome plating (0.05mm) prevents corrosion and reduces friction.
Stringent Quality Control (ISO 9001)
Every component is verified against strict quality benchmarks. We utilize Coordinate-Measuring Machines (CMM) for dimensional verification and Rockwell hardness testers. Our processes are certified under ISO 9001, guaranteeing a product you can trust.
Wide Application Suitability
Our purlins are vital in diverse sectors: large-span steel structures for the petrochemical and metallurgy industries, robust frames for commercial buildings, and durable supports for agricultural facilities and give-drainage systems. Their anti-corrosion properties (typically from G90 / Z275 galvanized steel) make them ideal for harsh environments.

Frequently Asked Questions (FAQ)
1. What's the difference between C and Z purlins, and can one machine really produce both?
C purlins have a 'C' shape, while Z purlins have a 'Z' shape, which allows them to be lapped at the joints for structural continuity and strength. Traditionally, you needed two separate machines. Our Automatic CZ Interchangeable purlin machine is revolutionary because its roller stands can be rotated 180 degrees and adjusted horizontally via PLC control, allowing it to form both C and Z profiles from the same set of rollers. This, combined with automatic size changes, makes it exceptionally versatile.
2. What is the typical lifespan of the rollers and dies in a purlin roll forming machine?
The lifespan is highly dependent on the material and manufacturing process. Our rollers, made from forged GCr15 steel and heat-treated to HRC 58-62, are designed for a lifespan of over 5 million linear meters of production under normal operating conditions with standard galvanized steel. The high-quality craftsmanship in our roll forming machine & die manufacturing ensures longevity far exceeding industry norms.
3. What material specifications are required for your purlin machine?
Our standard machine is designed for cold-rolled steel and galvanized steel coils with a yield strength of up to 345 Mpa. The standard thickness range is 1.5mm to 3.0mm. However, we can customize the machine to handle higher tensile strength steels (up to 550 Mpa) and different thickness ranges upon request.
4. How long does it take to change from one purlin size to another on the Automatic CZ machine?
This is a key performance indicator. For a fully automatic model, changing from one size to another (e.g., from C120 to C200) is done through the PLC touchscreen and takes approximately 5-10 minutes. The changeover from a C purlin to a Z purlin of the same size is equally fast. This drastically reduces downtime compared to manual machines which can take hours.
5. What kind of foundation is required to install a steel roll forming machine?
A stable, level concrete floor is essential for precision. We recommend a reinforced concrete foundation with a minimum thickness of 300mm (12 inches). We provide detailed foundation drawings and specifications with every machine purchase to ensure proper installation and long-term stability.
6. What does the PLC control system manage?
The PLC (Programmable Logic Controller) is the brain of the machine. It controls the entire production process, including: entering batch orders (quantity and length), automatic size adjustments of the rollers, servo-feeding for the punching system, precise length control for cutting, and system diagnostics. Our use of Siemens or Mitsubishi PLCs ensures global reliability and ease of service.
7. What post-sales support and training do you offer?
We provide comprehensive support. This includes detailed operation manuals and electrical diagrams, remote technical support via video call 24/7, and optional on-site installation and training by our certified engineers. We also maintain a stock of critical spare parts for rapid dispatch to minimize any potential downtime.
