Door and window materials must undergo inspection and acceptance upon arrival. One is visual inspection, checking for any damage or breakage; The second is size acceptance, checking the dimensions of the four sides of the frame, checking the squareness and curvature of the fan, and ensuring quality pre control before installation; The third is to distinguish authenticity. Based on different material identification methods, determine the authenticity of the material to prevent theft and replacement. In addition, it is necessary to inspect fasteners, hardware, reinforced profiles, and metal lining plates to see if the surface has been treated with anti-corrosion measures.

The verticality of door and window frames can be measured using a level ruler or a plumb bob. For doors and windows with a height of less than 2 meters, the verticality error should be less than 2 millimeters; When the height of doors and windows is greater than 2 meters, the error should be less than 3 millimeters; The levelness of door and window frames can be measured with a spirit level or by pouring water into the sliding track of the door and window frames. If the water level remains at a horizontal line, it indicates that the door and window frames are level; On the contrary, it means that the door and window frames are not installed horizontally; You can also use a long water pipe to measure and see if the water level at both ends is level.

2. Check the quality of glass installation

Glass should be flat, without spots or water marks; The inner and outer surfaces of double-layer glass should be clean, and there should be no dust or moisture inside the glass interlayer. The partition strip should not be lifted. The pressure strip with sealing strip must be tightly attached to the glass, and there should be no obvious gap at the joint between the pressure strip and the profile. The gap at the joint should be less than or equal to 1 millimeter.

3. Check the tightness of the frame and fan

The combination between the door and window frames and the leaf should be tight, and there should be no obvious gaps at the joint of the leaf sealing strip. When doors and windows are closed, there should be no obvious gap between the fan and the frame, and the sealing strip on the sealing surface should be in a compressed state.
