LW1200 Direct Square Forming Tube Mill Line

The LW1200 direct square forming tube mill line is designed for efficient production of large-size square and rectangular steel tubes. As a professional DFT tube mill, it adopts direct square forming technology to reduce unnecessary round-to-square deformation, helping manufacturers improve forming accuracy, tube surface quality, and production efficiency.

This square tube forming machine is suitable for producing structural square tubes and rectangular tubes used in construction, steel structures, bridges, machinery manufacturing, photovoltaic supports, industrial frames, and other heavy-duty applications. With multi-point pre-bending forming, electric adjustment, and PLC control, the LW1200 tube mill line provides a reliable solution for manufacturers who require stable output, accurate sizing, and flexible production.

Key Advantages of Square Tube Forming Machine

Direct Square Forming Technology

The Square Tube Forming machine uses direct square forming instead of the traditional round-to-square process. This helps reduce forming stress, improve tube corner quality, and support more stable production of square and rectangular tubes.

Electric Adjustment, Less Roller Change

The combined mold design allows electric adjustment during size changes, reducing the need for frequent roller replacement. For tube manufacturers, this means shorter changeover time, lower labor intensity, and improved production flexibility.

PLC Control and High Automation

The whole line is controlled by a PLC system with one-button reset function. The high level of automation helps improve operation consistency, reduce manual adjustment errors, and support continuous production.

Suitable for Large-Size Square and Rectangular Tubes

The LW1200 square tube forming machine is suitable for producing square tubes from 170×170mm to 300×300mm and rectangular tubes with height and width from 170mm to 300mm. It is a practical choice for factories producing medium and large structural steel tubes.

Stable Welding and Online Inspection

The Square Tube Forming line can be equipped with high-frequency welding, burr removal, zinc spraying, weld polishing, water cooling, eddy current flaw detection, and ultrasonic flaw detection. These configurations help improve weld quality and ensure that finished tubes meet industrial application requirements.
