Engineered by Zhongtuo for Precision and Surface Protection
As patio and pergola structures become more design-oriented and visible, manufacturers are placing higher demands on forming accuracy, coating protection, and machine safety.
To respond to these market needs, Zhongtuo has developed a 10×18 square tube roll forming machine specifically designed for pre-painted steel processing and export-oriented production lines.

With a strong background in cold roll forming technology, Zhongtuo delivers solutions that balance production efficiency, mechanical strength, and long-term reliability.
Optimized for Color-Coated Steel Coils
Processing pre-painted steel requires more than standard roll forming.
Surface damage, paint peeling, and friction marks are common issues if the machine design is not optimized.
For this reason, Zhongtuo integrates anti-scratch concepts throughout the entire forming line:
- An oil lubrication system at the material feeding section to reduce surface friction
- Belt-assisted supports at key contact points to avoid direct metal contact
- Cr12 forming rollers with precision machining and heat treatment for smooth forming

Light steel keel roll forming machine with high precision roller stations
As a result, the finished 10×18 square tubes feature clean surfaces, uniform geometry, and sharp edges—ideal for architectural and decorative outdoor applications.
Rigid Gantry Frame for Stable Continuous Production
To guarantee forming stability during long production cycles, the machine is built on a gantry-type frame structure.
This design improves overall rigidity and keeps roller alignment stable, even under continuous load.
At the same time, a gear-driven transmission system synchronizes all forming stations, minimizing vibration and ensuring consistent tube dimensions from start to finish.
Intelligent Control System with Export-Grade Safety Design
This square tube roll forming machine combines automation and safety in one integrated system.
Control Configuration
- Siemens touch screen
- Siemens frequency inverter
- Servo tracking cutting for precise length control
- Chinese–English bilingual interface
Operators can easily monitor production parameters and adjust settings with high accuracy.
