There are four ways to judge the quality of a room door: First, stand two meters away from the door, observe the shape and workmanship of this door, see if its door shape is neat, whether the surface color is pure and the texture is clear. Second, stand up to half a meter, the seams of the door, the small part of the frame and other small parts are in place to see if it is not spliced, white and so on. Third, look at the light and see if the shadow of the reflection is deformed, so that the flatness of the door surface can be checked. Fourth, touch the paint surface of the door by hand, feel that there is a slight blistering, etc. Do not touch the palm with your hand when touching it. You should touch it with your back. Because the back of the person's hand is sensitive, it will feel relatively small. Variety. ZHEJIANG HESHUO TECHNOLOGY CO.,LTD , https://www.hosuocn.com
