Steel Purlin Machines Roll Former

Steel purlins such as C, Z, Sigma (M-shaped), and Omega profiles are essential in modern industrial steel buildings and are also applied in some residential projects. To meet these needs, advanced roll forming machines are available for producing C/Z/U steel purlins, Sigma purlins, and Omega purlins with high precision and efficiency.

Common steel purlin fabrication equipment are like C purlin roll forming machines, Z purlin roll forming machines, and interchangeable C/Z purlin roll forming machines capable of producing both without changing rolls or dies. Additionally, Sigma (M-shaped) and Omega purlin roll forming machines have been developed to satisfy the demand for higher strength and versatile structural use.

Sigma Purlin Roll Forming Machine

Highlights: PLC Control, Fast Changeover, Full Automation

A SIGMA purlin roll forming machine is specially engineered to produce high-strength Σ-shaped or M Shaped steel purlins, mostly used in large-span structures, warehouses, and modern steel buildings. Compared with traditional C or Z purlins, SIGMA purlins offer higher load-bearing capacity and improved structural stability due to their unique geometry. With a PLC control system, this production line integrates automatic decoiling, leveling, punching, forming, and cutting into one continuous process,achieving full automation and high precision. With flexible size adjustment design, the SIGMA purlin roll forming machine greatly improves production efficiency.
Q1: What types of profiles can steel purlins roll forming machines produce?

A: Our steel purlin roll forming machines are designed to produce a wide range of steel sections, including C purlins, Z purlins, U profiles, Omega sections, and Sigma beams. These profiles are widely used for steel structure buildings, warehouses, factories, and solar mounting systems.

Q3. What materials and thicknesses can the machines process?

A: The machines are suitable for galvanized steel, hot-rolled steel, cold-rolled steel, and high-tensile steel, with thickness ranges from 1.5 mm to 3mm, 2.0mm to 4.0 mm and 3mm to 5mm, depending on model specifications.

Q5: What is the typical production speed of these roll forming machines?

A: Depending on configuration, our purlin machines can achieve forming speeds of 10–25 meters per minute, with flying or hydraulic punching and cutting systems that allow high-speed, continuous production.

Q7: What are the advantages of Sigma and Omega purlins compared to C/Z sections?

A: Sigma purlins are known for their high load-bearing capacity with reduced material usage, while Omega sections are commonly used in lightweight structures and cladding support. Both offer specialized solutions that complement traditional C and Z purlins.

Q2: How does an interchangeable C/Z purlin roll forming machine work?

A: The automatic interchangeable system allows the machine to switch between C and Z profiles quickly without replacing the entire roll set. With servo motors and PLC control, the changeover can be completed in minutes, increasing efficiency and reducing downtime.

Q4: Are the width and height of the purlin adjustable?

A: That depens on what profiles. For C/U/Z and Sigama purlins, yes, the machines feature automatic or manual adjustment systems, enabling users to produce different web widths, flange heights, and lip sizes from a single machine, making it highly versatile for various project requirements.

Q6: What control system is used?

A: All machines are equipped with advanced Siemens or Panasonic PLC systems, user-friendly touch screens, and encoder length control. For Servo trackign system, Xinjie rollforming specialized PLC control system is applied. This ensures accurate cutting, minimal material waste, and simple operation.

Q8: How long is the lifespan of a purlin roll forming machine?

A: With a heavy-duty frame, precision-machined rollers, and gearbox transmission, the expected lifespan of the machines is 15–20 years with proper maintenance, making them a reliable investment for long-term production.
