Hydraulic C Profile Purlin Roll Forming Line with Punching System 30–40 m/min, Customized

C purlins are widely used in steel structure buildings as roof purlins, wall members, framing components, and solar support structures. To meet the demand for different profile sizes and continuous production, the 0.7–2mm C Purlin Roll Forming Machine provides an efficient solution for converting galvanized or pre-painted steel coils into accurately formed C-shaped profiles.

Using continuous cold roll forming technology, the machine gradually shapes the metal strip through multiple roller stations without heating the material. This production method helps maintain consistent profile dimensions while providing a practical solution for manufacturers handling different C purlin specifications.

The machine can also be configured with automatic punching, hydraulic cutting, and customized control systems according to the customer's production requirements.

Continuous Roll Forming for C-Shaped Steel Profiles

The production process starts with the steel coil being loaded onto the decoiler. The strip then enters the forming section, where a series of precision rollers progressively bends the material into the required C-shaped profile.

For materials with a thickness range of 0.7–2mm, the forming system is designed to provide stable feeding and gradual deformation. The use of multiple forming stations helps reduce excessive stress during the forming process and contributes to a uniform finished profile.

Depending on the project requirements, the production line can be equipped with:

• Automatic hydraulic decoiler

• Leveling and feeding system

• Multi-station roll forming system

• Online punching unit

• Hydraulic or flying cutting system

• PLC control cabinet

• Hydraulic power system

• Automatic length and quantity control

This configuration allows the entire production process to be managed through one integrated system.

Designed for 0.7–2mm Steel Coil

The machine is suitable for processing PPGI, GI, and aluminum materials with a typical thickness range of 0.7–2mm.

The forming rollers are manufactured from GCr15 material with heat treatment, providing the required surface hardness and wear resistance for continuous production. An 80mm solid shaft supports the forming rollers, while the welded steel machine frame provides a stable foundation for the complete forming section.

The standard drive system uses chain transmission, while the electrical and control components can be customized according to the customer's preferred brands and local electrical requirements.

Automatic Punching for Structural Applications

For steel structure applications, C purlins often require connection holes for bolts, brackets, or other structural components. Adding an online punching system allows holes to be produced before the final cutting process.

The punching system can be configured according to the customer's drawings, including different hole shapes, hole positions, and hole spacing.

This reduces the need for separate drilling operations after roll forming and helps simplify the downstream installation process.

For projects requiring different hole patterns, the PLC control system can coordinate feeding, punching, forming, and cutting according to the programmed production parameters.

Automatic Length Cutting and PLC Control

After the profile passes through the forming stations, the cutting system produces finished C purlins according to the preset length.

The PLC control system allows operators to set production parameters such as:

• Profile length

• Production quantity

• Cutting quantity

• Operating speed

• Punching positions

• Production batches

The automatic control system helps reduce manual intervention during continuous production. When integrated with servo positioning and an appropriate cutting configuration, the machine can maintain consistent finished lengths throughout the production run.

Applications of C Purlin Profiles

C-shaped cold-formed steel profiles have a wide range of applications because they combine relatively low weight with useful structural strength.

Steel Structure Buildings

C purlins are commonly installed between main structural frames to support roofing and wall systems. They can be manufactured in different widths, heights, and lengths to match specific building designs.

Warehouses and Industrial Buildings

For warehouses, workshops, logistics centers, and other large-span structures, continuous C purlin production allows manufacturers to produce structural members according to project requirements.

Solar Mounting Structures

C-shaped steel profiles can also be used in photovoltaic support structures. Galvanized steel is particularly suitable where corrosion resistance is required for outdoor applications.

Light Steel Construction

C profiles are widely used as framing components in light steel buildings and prefabricated structures. Their standardized dimensions make them convenient for factory production and on-site assembly.

Stable Forming with a Heavy-Duty Machine Structure

The forming quality of a C purlin depends on the coordination between the rollers, shafts, machine frame, feeding system, and material properties.

This machine uses a welded steel frame and multiple forming stations to progressively shape the coil. The 80mm solid shafts provide support for the roller assemblies, while heat-treated GCr15 forming rollers are designed for continuous operation.

The forming section can also be customized for different profile dimensions and production requirements.

Flexible Configuration for Different Production Requirements

Not every C purlin manufacturer has the same production requirements. Some projects focus on high-speed production, while others require frequent changes in profile dimensions or complex punching patterns.

For this reason, the C Purlin Roll Forming Machine can be configured according to the customer's specific application.

Possible customization options include:

• Different C purlin dimensions

• Customized forming stations

• Automatic or manual decoiler

• Different punching patterns

• Customized cutting length

• PLC brands and electrical components

• 380V, 440V, or other voltage requirements

• Different production speeds

• Additional feeding and leveling systems

This makes the equipment suitable for both standard production lines and customized steel profile manufacturing projects.

C Purlin Roll Forming Machine for Efficient Steel Profile Manufacturing

The 0.7–2mm C Purlin Roll Forming Machine combines continuous cold forming, automatic control, optional online punching, and automatic cutting into one production line.

From coil feeding to finished C purlin cutting, each stage can be coordinated through the PLC control system to create a more streamlined production process.

If you are planning to manufacture C purlins for steel structures, warehouses, solar mounting systems, or light steel buildings, the machine can be customized according to your required profile size, material thickness, punching pattern, production speed, and electrical standard.
