A CUZ sigma purlin roll forming machine is an efficient, automated cold roll forming system designed to produce C-, U-, Z-, and sigma profiles (purlins). It is widely used in construction, steel structure projects, and roof/wall support systems. The machine can accurately manufacture profiles in various specifications according to different design requirements, providing strong and reliable structural support.
Using advanced cold roll forming technology, the equipment continuously forms metal coil through multiple precision rollers to produce profiles with accurate dimensions and high strength. The machine is designed to handle coils of different thicknesses and widths, meeting the requirements of high-volume production while maintaining excellent accuracy.
Equipped with a PLC automatic control system and a touchscreen interface, the machine is easy to operate. Users can quickly adjust forming parameters for different production needs, improving efficiency. It also supports automatic feeding, cutting, and scrap discharge, further reducing manual intervention and lowering production costs. Built with high-quality materials and featuring low energy consumption, the equipment ensures stable long-term operation and a long service life. With a robust structure, it performs reliably in high-intensity production environments, making it essential equipment for modern construction and steel structure industries.

READ MOREThe C U Z Sigma Purlin Machine is a versatile piece of equipment designed for the efficient production of multiple purlin profiles. As an essential component in modern construction, this machine allows for the seamless manufacturing of C, U, Z, and Sigma shaped steel purlins used in roofing and wall support systems. Shanghai Sihua Precision Machinery Co., Ltd. specializes in the research and development of automatic high-speed flying shear roll forming machines, ensuring that each purlin machine delivers precision, speed, and durability.
Selecting the right machinery requires a deep understanding of technical parameters. The following table outlines the typical specifications for a high-performance purlin machine developed by Shanghai Sihua Precision Machinery Co., Ltd.:
| Parameter | Specification Details |
| Product Name | C U Z Sigma Purlin Machine |
| Machine Type | Automatic High-Speed Flying Shear Roll Forming Machine |
| Forming Profiles | C, U, Z, and Sigma shapes |
| Material Thickness | 1.5mm - 3.0mm (Customizable) |
| Forming Speed | 15 - 30 m/min (High-speed mode) |
| Roller Material | High-strength alloy steel with surface quenching |
| Control System | PLC Automatic Control System |
| Cutting Method | Hydraulic Flying Shear |
| Working Voltage | 380V/50Hz/3Phase (Adjustable) |
One of the core competencies of Shanghai Sihua Precision Machinery Co., Ltd. is the integration of flying shear technology. Unlike traditional stop-cut systems, the flying shear mechanism allows the C U Z Sigma Purlin Machine to cut materials to length without halting the production line. This continuous operation significantly increases output and ensures smooth, burr-free cuts, making it ideal for large-scale industrial projects.
The versatility of the C U Z Sigma Purlin Machine allows it to serve various structural needs. Different profiles offer specific mechanical benefits for construction:
| Profile Type | Primary Application | Structural Benefit |
| C Purlin | Roofing and wall purlins | Standard load-bearing, easy installation |
| Z Purlin | Continuous purlin systems | Excellent for overlapping and nesting |
| Sigma Purlin | Large-span structures | Higher section inertia, superior load capacity |
| U Purlin | Support beams and framing | Simple geometry for basic support needs |
Shanghai Sihua Precision Machinery Co., Ltd. is a high-tech enterprise holding 42 utility model patents and 11 invention patents. This dedication to innovation ensures that the C U Z Sigma Purlin Machine features high-precision rollers and a robust machine frame. The company's expertise extends beyond purlin machines to include drywall profile machines, strut channel machines, and automotive high-strength steel roll forming machines, providing a comprehensive solution for the metal forming industry.
While a specialized machine may produce only one type, the C U Z Sigma Purlin Machine is designed to produce both. The main difference lies in the profile shape: C purlins have a C-shaped cross-section used primarily for simple spans, while Z purlins have a Z-shape that allows for nesting and overlapping, making them more efficient for continuous beams across multiple spans. Shanghai Sihua Precision Machinery Co., Ltd. designs machines that allow for quick changeovers between these profiles to maximize production flexibility.
A flying shear machine cuts the material while it is still moving. The shear carriage accelerates to match the speed of the steel strip, performs the cut, and then returns to the start position. This technology, championed by Shanghai Sihua Precision Machinery Co., Ltd., eliminates the stop-and-go cycle of traditional cutting, thereby boosting the speed of the C U Z Sigma Purlin Machine significantly.
This machine is typically designed to process galvanized steel coils and black steel coils. The standard thickness capacity ranges from 1.5mm to 3.0mm, though Shanghai Sihua Precision Machinery Co., Ltd. offers customization options for thicker materials or high-strength steel grades, leveraging their experience in automotive high-strength profile machinery.
Choosing Shanghai Sihua Precision Machinery Co., Ltd. ensures access to advanced technology and reliable support. As a professional manufacturer based in Shanghai with a high-standard talent team, Sihua integrates precision engineering into every machine. Their equipment features high automation levels, durable components, and the backing of numerous patents, ensuring long-term operational value for clients worldwide.
