Thermally broken aluminum profile: Today, Thermally broken aluminum alloy doors and windows processing are the most commonly used aluminum profiles, with insulation, energy-saving and other advantages not available in other profiles. However, because of its complicated cross-sectional shape, they are prone to wrinkles in the processing of cold stretch forming, affecting the appearance of windows and doors.

As a result of more than ten years of working experience, in-depth studies, and continuous research, Beijing Shengda Weiye Bending Company has finally successfully solved the above problems. Now, the minimum bending radius of the arc bridge aluminum can reach R = 260mm, and can be stretch-formed into an arc shape with straight line segments on the sides, so that the doors and windows will look neat, smooth and more beautiful.
