Zhongtuo Cee/Zee/U-Channel/Angle/Eave Combination Tooling Roll Forming Machine for Steel Substructural Components

Modern steel buildings rely heavily on secondary framing systems to achieve structural stability, efficient installation, and long-term durability. Substructural components such as Cee purlins, Zee purlins, eave struts, channels, hats, and angle profiles form the backbone that supports roof and wall systems while connecting to the primary steel frame.

Our advanced Substructural Components Roll Forming Machine is specially engineered for the fully automatic production of high-strength cold-formed steel framing members. The line combines intelligent punching, rapid profile change, precision servo feeding, and automatic stacking into one integrated manufacturing solution. It is widely used for commercial buildings, warehouses, industrial workshops, agricultural structures, solar mounting systems, and metal building framing projects.

Unlike traditional fabrication methods that require excessive welding and manual cutting, this production line delivers accurate roll-formed profiles with high efficiency, stable quality, and reduced labor costs. As a result, manufacturers can improve productivity while maintaining consistent dimensional precision.

Cold-formed steel secondary framing systems play a critical role in modern construction projects. These structural members provide reliable support for roofing and wall cladding systems while improving on-site installation efficiency.

Typical applications include:

• Commercial and industrial steel buildings
• Warehouse and logistics centers
• Agricultural buildings and storage facilities
• Roof retrofit and metal-over-metal recovery systems
• Solar racking and mounting structures
• Residential steel framing systems
• Wall framing support for metal panels
• Mansard framing and architectural cladding systems

Because the profiles are manufactured with precision pre-punched holes and accurate dimensions, contractors can complete bolt-up installation quickly and efficiently.

Main Profiles Produced by the Machine

This production line is designed to manufacture multiple structural framing profiles with fast automatic size adjustment.

Cee Profile Purlins

C purlins feature a classic “C” cross-section and are commonly used in shorter spans, wall girts, and applications requiring flat mounting surfaces. The machine supports multiple bending angles including 87.6°, 85.2°, 82.9°, 80.5°, 76°, 71.6°, and 63.4°.

Cee/Zee Purlin Roll Forming Machine for Structural Support Systems

The Cee/Zee purlin roll forming machine manufactures structural framing members widely used in steel warehouses, workshops, logistics centers, solar mounting systems, and metal building projects. Cee profiles provide strong flat mounting surfaces for wall framing and shorter spans, while Zee profiles create continuous beam action through overlapping installation.

In addition, the line supports multiple bending angles and automatic profile size adjustment, allowing manufacturers to switch specifications quickly without complicated manual setup. The servo-controlled adjustment system improves production flexibility while maintaining accurate profile dimensions throughout long production runs.

Because the machine processes galvanized steel, black steel, Q195, Q235, Q345, ST37, and ST52 materials, it easily adapts to different structural load requirements and regional building standards.

U-Channel and Angle Profile Roll Forming Machine with Combination Tooling

This U-channel and angle profile roll forming machine adopts intelligent combination tooling technology, enabling multiple profile types to be produced on one production line. Manufacturers can reduce equipment investment while expanding product capacity for different construction applications.

The production line includes a high-performance servo punching system with six punching stations, ensuring precise hole positioning for bolt-up installation. Meanwhile, the automatic centering guide system continuously adjusts to strip width variations, which improves punching accuracy and prevents deviation during high-speed operation.

The integrated roll forming system uses gearbox transmission with spiral bevel gears for stable power transfer and reliable long-term performance. Furthermore, the forming rollers are manufactured from heat-treated Cr12MoV steel, providing excellent wear resistance and long service life under continuous production conditions.

Eave Strut Roll Forming Machine with Automatic Feeding and Punching

The eave strut roll forming machine section is specially engineered for producing roof-to-wall connection members used in steel building structures. Eave struts strengthen the transition area between roof systems and sidewalls while improving structural alignment and installation stability.

To support continuous production, the line is equipped with an 8-ton hydraulic decoiler and automatic feeding trolley. The pneumatic pressing arm and reinforced braking system prevent coil loosening and maintain stable material feeding throughout operation. At the same time, the leveling and servo feeding system flattens the strip steel before punching, ensuring excellent profile quality after forming.

The hydraulic punching station operates with a 55KW hydraulic system and oil cooler, allowing the equipment to maintain stable oil temperature even under high-intensity production environments. As a result, the machine achieves reliable punching performance and consistent operation during long production cycles.

Automatic Cee/Zee/U-Channel Roll Forming Machine Technical Parameters

Intelligent Combination Tooling Roll Forming Machine with Automatic Stacking

The finished profiles are transferred automatically through the intelligent stacking system after cutting. The system performs profile conveying, turning, suction gripping, transverse movement, and palletizing without manual handling. Electromagnetic suction cups automatically adjust according to profile length, while servo-driven rack-and-pinion movement guarantees accurate positioning.

Additionally, the PLC control system manages the entire production line through an LCD touchscreen interface. Operators can monitor machine status, modify production parameters, and check fault indicators in real time. The line supports both manual and automatic operating modes, which simplifies maintenance and improves production flexibility.

With automatic profile adjustment, high-speed punching, precision roll forming, and intelligent stacking, this Cee/Zee/U-Channel/Angle/Eave combination tooling roll forming machine provides an ideal solution for producing durable and accurate steel substructural components for modern construction industries.
