Purlin roll-forming machines are key equipment in the production of steel structural building materials. They can process galvanized steel sheets, color-coated steel sheets, and other metal sheets into C-, Z-, and U-shaped purlins, providing support for building roofs and walls.
Based on cold roll-forming technology, the machine uses 15-25 sets of sequentially arranged rollers to gradually shape the sheet material without preheating it. Each set of rollers is responsible for a specific bending angle, and through multiple steps, a standard cross-section is achieved while preserving the sheet material's original mechanical properties. The entire process is fully automated, from coil unwinding and guide correction to roll-forming, cut-to-length cutting, and finished product stacking—all precisely controlled by a PLC system, minimizing manual intervention.
The machine's core components offer exceptional performance: a hydraulically tensioned unwinding frame securely grips the coil material to prevent conveying deviation; a guide mechanism uses straightening wheels to adjust the sheet material's position in real time; forming rollers are constructed from alloy steel with a hardness of HRC55 or higher, ensuring long-term, high-precision processing; and a hydraulic flying saw cutting system achieves ±1mm cutting accuracy without affecting continuous production.
This equipment offers significant advantages: high efficiency, with continuous processing speeds reaching 10-30 meters per minute and a single-shift production capacity of 15,000 meters, 5-8 times that of traditional processes. High precision, with a cross-sectional dimension error of ±0.5mm and a straightness error of ≤1mm/m, ensures precise installation. Material utilization exceeds 95%, reducing waste. High flexibility, with adjustable dimensions, allows for accommodating plates 0.8-3mm thick and 100-300mm wide, and produces purlins 1-12 meters long. Energy consumption is 60% lower than hot rolling, and the roll life exceeds 500,000 meters, resulting in low maintenance costs.
This equipment is widely used in steel structures such as industrial plants, warehouses, and stadiums, driving the trend toward lightweight and modular construction. It is a vital piece of equipment for modern industrialized construction.
