Curtain Wall Square Tube

The manufacturing process of Curtain Wall Square Tube for curtain walls is extremely sophisticated, with each step affecting the quality and performance of the final product. First, carefully selecting high-quality steel billets is fundamental to creating high-quality square tubes for curtain walls. Through hot rolling or cold rolling, the steel billets are processed into steel strips of uniform thickness and with a smooth surface, laying a solid foundation for subsequent forming processes.

Next, these processed steel strips are fed into a precision forming unit. Under precise mechanical action, they are gradually bent into a square shape. This process places extremely high demands on the precision of the machinery and the skills of the operators; even slight deviations can affect the forming quality of the square tube.

In the welding process, advanced high-frequency induction welding technology is employed. Utilizing the thermal effect generated by the high-frequency current, the metal at the interface rapidly fuses to form a strong weld. The factory's welding line is equipped with a professional real-time monitoring system that precisely controls the welding temperature and flexibly adjusts the current based on actual conditions, ensuring that every weld is of superior quality.

After welding, Curtain Wall Square Tube requires meticulous deburring and straightening processes. Deburring prevents burrs from scratching other parts, while straightening effectively eliminates internal stress and ensures that the cross-section of the square tube exhibits perfect squareness.
