The U purlin roll forming machine is designed for continuous production of U-shaped steel purlins widely used in modern construction structures. It provides stable forming accuracy, high efficiency output, and reliable performance for industrial-scale manufacturing environments.
The machine enables uninterrupted forming of steel coils into U purlin profiles, ensuring stable speed and consistent output quality for large-scale production requirements.
The system supports quick adjustment of different U purlin sizes, allowing multiple specifications to be produced without complex roller replacement.
The machine structure is built with heavy-duty welded steel, ensuring stability during long-term continuous operation and reducing vibration impact during production.
High-quality rollers ensure accurate shaping of steel strips into consistent U purlin profiles, maintaining dimensional stability throughout production cycles.
The hydraulic cutting unit provides smooth and precise cutting results, ensuring clean edges and reducing secondary processing requirements.

Purlins, produced by roll-forming metal sheets, serve as the "skeletal support" of steel structures. Their role spans multiple aspects, including structural construction, performance assurance, and industry development:
Core Load-Bearing Support
As the direct load-bearing components of the roof and wall systems, purlins transfer roof loads (such as rain, snow, and equipment weight) and wall loads to the main structure, including steel columns and beams, forming a stable load-bearing system. For example, in industrial plants, C-shaped purlins arranged at intervals of 1.5-2 meters can support roof spans exceeding 10 meters, ensuring the overall structural safety of the building.
Simplifying the Construction Process
Roll-formed purlins feature uniform specifications and high precision (cross-sectional tolerance within ±0.5mm). They require no on-site secondary processing and can be directly bolted to the main structure, significantly shortening installation time. Compared to traditional welded purlins, prefabricated installation increases efficiency by over 30%, reduces on-site hot work, and mitigates construction safety risks.
Adapting to Diverse Buildings
The equipment can flexibly produce purlins in various cross-sections, including C, Z, and U, to meet diverse building requirements. Z-shaped purlins, due to their excellent bending resistance, are commonly used in large-span warehouses (spans of 15-30 meters). U-shaped purlins are suitable for wall support and adapt to curved, inclined, and other unusual architectural shapes, helping to realize the design vision of complex buildings such as stadiums and exhibition halls.
Promoting the Development of Green Buildings
The cold-formed forming process reduces steel loss (with a utilization rate exceeding 95%) and produces purlins with a low deadweight (40% lighter than traditional hot-rolled components), reducing the load on the building foundation and indirectly reducing concrete usage. Furthermore, galvanized purlins are corrosion-resistant and have a lifespan of over 30 years, meeting the "low-carbon, durable" requirements of sustainable construction.
Supporting Modular Construction
Standardized purlins can be combined with prefabricated wall and roof panels to form modular building units, accelerating the transition of steel structure construction towards industrialized and integrated design. For example, in the construction of a logistics industrial park, modular factories using roll-formed purlins can reduce the construction period to one-third of traditional methods.
In short, by providing high-quality and diverse purlins, purlin roll-forming machines not only ensure the stability and safety of building structures, but also promote the upgrading of the construction industry towards efficiency, greenness, and industrialization.
