First: the thickness of the contour. The profile thickness of Zunshang doors and windows is between 1.2-3.0. For example, the profile thickness of high-end series products such as Huangzuan 100, Happiness E-Home, Nordic Sunshine, etc. are all above 1.8.
Second: the width of the product, that is, the cross-sectional width of the profile. Width is an important index that directly determines whether the product is stable during installation and use. The wider the width, the more expensive the price will naturally be. In Zunshang's best-selling series, Gemstone 108 and Gemstone 138 are the most popular products during installation and use.
Third, whether it is ammonia glass. That is, whether there is ammonia between two insulating glasses, ammonia can prevent the glass from deforming. This is one of the points that distinguish between good and bad products.
Fourth, whether the hardware materials used are imported, such as Paige's wind brace and imported hardware accessories of well-known brands such as Haobo, because these hardware accessories directly determine the service life.
