With the widespread use of plastic steel profiles, some shortcomings have also been exposed. There are many specifications from various manufacturers, and the versatility of the window frames of the same window is relatively narrow. After assembling the windows, most manufacturers place the small side facing the sun due to site reasons, which reduces the anti-ultraviolet performance and causes the small side to change color. The single color of PVC profiles cannot meet the diverse needs of customers.

[0004] As the main sales product of PVC new material workshop, profiles have a certain market foundation after three years of promotion. Combined with the market promotion in recent years, although our company's 65B and 76A series products meet the market requirements for similar products and engineering project bidding, they still have the defect of poor versatility and few types.
