💡What Is the Sigma Purlin Roll Forming Machine Used For?
The sigma purlin roll forming machine specializes in producing high-strength Σ purlins—cold-formed steel sections with a unique sigma (Σ) profile. These purlins are essential, load-bearing components in modern construction, often referred to colloquially as sigma beams due to their structural use. They are critical for supporting roof sheets, wall cladding, and ceiling panels across various sectors, including large-scale warehouses, industrial factories, commercial buildings, and residential homes. Their exceptional strength-to-weight ratio makes them a preferred choice for large-span structures where material efficiency and structural integrity are paramount. If your business needs a durable, high-speed sigma beam roll forming machine, Beli RollForming has the solution.
Versatility and Production Capabilities
Our advanced sigma purlin roll forming machine is designed for maximum versatility, allowing you to cater to a diverse range of project requirements. You can use our machine to create purlins in customizable sizes:
Purlin Height: Ranging from 80mm to 300 mm (custom heights readily available).
Material Thickness: Standard production handles 1.5-3.0 mm mm, with specialized models capable of running 2.5 up to 5.0 mm.
Material Type: Optimized for Galvanized Steel Coil, but compatible with Stainless Steel options.
This wide operational range ensures that your investment in a sigma purlin roll forming machine can handle everything from small residential roofing projects to major industrial infrastructure. A key feature is the integrated flying hydraulic cutting system, which guarantees clean, accurate lengths without the need to stop the production line. This continuous operation capability is critical for achieving high daily output and meeting tight construction deadlines globally.
🗝️Key Components of the Sigma Purlin Roll Forming Machine
Our sigma purlin roll forming machine is built using heavy-duty, low-maintenance components, engineered for industrial-scale reliability and uptime.
🛠️ 3-in-1 Heavy Duty Uncoiler, Leveler, and Feeder
This integrated unit is the starting point for high-efficiency production and is a hallmark of our premium sigma purlin roll forming machine design. It eliminates the need for standalone equipment, saving valuable factory floor space:
Uncoiler: Robustly handles standard 5-ton steel coils, with a 10-ton option available for extended, uninterrupted runs. Features tool-free coil loading for rapid changeovers.
Leveler (Straightener): Actively corrects the curvature and shape of the coiled material, ensuring perfectly flat material feed into the main mill. This critical step drastically reduces material waste caused by bent or stressed steel, optimizing the output of the sigma purlin roll forming machine.
Feeder: Utilizes a precise servo-driven mechanism to exactly match the material speed to the roll forming mill. This synchronization prevents material jams, reduces wear on the rollers, and ensures the uniform quality of the finished sigma purlin.
⚙️ Precision Punch Holes Device
Integrated directly into the line of the sigma purlin roll forming machine, the servo-motor driven punch system delivers superior accuracy. It can create pre-set holes for fasteners, ventilation, or custom architectural patterns. This feature allows for flexible customization—for instance, 20mm spacing for screws—and eliminates the need for slower, post-forming drilling operations.
🏭 Heavy Duty Roll Forming Part – The Heart of the Machine
The core of the sigma purlin roll forming machine is engineered for high-speed, long-term performance:
Roll Forming Feeder: Ensures a steady, consistent material flow into the forming mill at high speeds.
Heavy Duty Roll Forming Mill: Features 18 robust forming stands (with 20-24 stands optional). The rollers are precision-machined from D2 steel, which offers exceptional hardness and wear resistance, guaranteeing a lifespan of 10+ years with proper maintenance. This machinery is often considered the most efficient type of sigma beam roll forming machine available on the market today.
Gear Box Transmission: Provides smooth, reliable torque delivery to all forming stands, essential for handling thick gauge materials quietly and efficiently.
Straightener: A post-forming straightener fixes any residual shape deviation, ensuring every purlin exits the sigma purlin roll forming machine perfectly straight and ready for construction.
Flying Hydraulic Cutting: The high-speed hydraulic cutter performs clean, precise cuts on the fly, maximizing the effective line speed up to 15 M/Min without pausing the roll forming process.
🖥️ Advanced Controller System
Touchscreen PLC (Siemens/Mitsubishi optional) with real-time monitoring. Operators can adjust settings, view error logs, and export production data—user-friendly for global teams.
🔋 Hydraulic System
3 kW motor powers the uncoiler, 22 KW for punch, and 11 KW for cutting mechanism. Sealed components prevent leaks—ideal for dusty factory environments.
📦 Auto Stacker
Collects finished purlins automatically—holds up to 100 units (size-dependent). Reduces manual labor and keeps production running smoothly.
