1. Beautiful appearance, better thermal insulation and sealing performance, seamless welding is an upgraded version, adopts seamless welding technology, the outer aluminum is flat and the layer is simple; No concave convex feeling, more beautiful and more decorative performance; It can make doors and windows better play the effect of sound insulation and heat insulation.
2. The frame is more firm, not easy to deform and prolong the service life of doors and windows. We know that the thermal expansion and cold contraction of external aluminum due to seasonal changes may cause water seepage of doors and windows due to cracks, so that the internal profiles are corroded and endanger the service life of doors and windows. If the doors and windows adopt the seamless welding process, the above problems are well avoided, the window frame is stronger, and the spraying at the joints of doors and windows is more uniform.
