uPVC profiles all adopt multi-cavity structure, with isolated drainage cavity and reinforcement cavity, so that the assembly of the steel lining and the processing of the sink are independent of each other, which improves the service life of the profiles. The drainage groove is processed by the method of staggering the inner and outer positions, which can prevent the entry of cold wind and dust, and can discharge the accumulated water smoothly even when the wind pressure is large. There are a wide variety of connecting profiles and good matching properties. They are suitable for the assembly and connection of 14 series of plastic-steel profiles, and can be selected according to the requirements of wind pressure strength or user preferences.
