Product Introduction:
The purlin rolling machine is designed for continuous manufacturing of steel purlins used in modern construction structures. It provides stable forming accuracy, high efficiency output, and reliable performance for industrial-scale production environments.
The machine enables uninterrupted rolling forming of steel coils into purlin profiles, ensuring stable production speed and consistent quality output for large-scale manufacturing.
The system supports adjustable purlin sizes, allowing different specifications to be produced without complex mechanical replacement, improving production flexibility.
The frame is built with reinforced welded steel to ensure long-term stability and resistance to deformation during continuous high-load operation.
High-quality rollers ensure accurate shaping of steel strips into consistent purlin profiles, maintaining dimensional stability throughout production cycles.
The hydraulic cutting unit provides smooth, precise cutting results with clean edges, reducing secondary processing requirements.

The Purlin Roll Forming Machine is a high-precision automated equipment designed specifically for cold roll forming. Its core function is to continuously roll metal sheets (including galvanized steel, color-coated steel, cold-rolled steel, and other materials) through multiple sets of rollers, forming purlins with specific cross-sectional shapes such as C-, Z-, and U-shaped. Purlins, as key load-bearing components in the roof and wall support systems of steel structures, play a vital role in modern architecture.
I. Core Function and Operating Principle
Cold roll forming process
Using a room-temperature processing mode, the metal coil or sheet does not require preheating. Dozens of roller dies arranged in a specific sequence continuously shape the sheet using progressive pressure. Each set of rollers is responsible for producing a specific bend angle and curvature. Through multiple precise shaping steps, the sheet is ultimately formed into a purlin cross-section that meets engineering design standards. Throughout the entire process, the sheet's mechanical properties are effectively preserved, avoiding material damage caused by high-temperature processing.
Automated Process
The equipment is equipped with a fully automated control system, eliminating the need for human intervention in critical processes, from securing the metal coils on the unwinding rack, to the corrective conveying of the sheets via guides, to continuous shaping in the roll-forming unit, to precise cutting after length measurement, and finally to the automatic stacking and output of the finished purlins. This highly automated operation not only reduces manual errors but also allows for flexible adjustment of operating parameters based on production needs, significantly improving the stability and efficiency of mass production.
II. Main Types and Applications
Based on the cross-sectional shape and functional characteristics of the purlins being processed, common types can be categorized as follows:
C-Section Purlin Machine: Specializes in processing purlins with a "C" cross-section. Its compact cross-section design and low weight allow for direct bolting to the main steel frame during installation, making it easy to operate. It is suitable for small and medium-sized industrial plants, warehouses, and lightweight steel structures with spans of 6-15 meters. Z-Shaped Steel Purlin Machine: The Z-shaped purlins produced are designed with overlapping and interlocking upper and lower flanges. In long-span buildings, continuous overlap creates a monolithic load-bearing structure, offering enhanced wind load resistance and load-bearing capacity. Suitable for large-scale factories and stadiums with spans of 15-30 meters, it performs particularly well in snowy and windy areas.
Multi-Function Purlin Machine: Equipped with quickly interchangeable modular roller dies, this machine can flexibly switch between producing C-shaped, Z-shaped, and U-shaped purlins. It can also accommodate sheet metal of varying thicknesses, making it particularly suitable for building materials manufacturers with varying order specifications and for projects that need to meet diverse building requirements.
