Doors and windows are composed of frame material, fan material, middle truss and pressure line, etc. The following is their detailed introduction: Frame material: the material connected to the wall in the door and window material. Its main feature is that the surface where it meets the wall is mostly flat, which is fixed on the wall and cannot be moved.  Fan material: The material that can be opened in doors and windows. Its characteristic is the ability to move.   Zhongting: A material that divides the rectangle formed by the frame material into several small rectangles.  True middle stand: fixed on the frame material;   false middle stand: fixed on the fan material   Pressing line: indoor side, the profile used for fixing the glass. Round pressure line: suitable for 45-degree splicing, square pressure line: suitable for 90-degree splicing. How to distinguish the advantages and disadvantages of aluminum profiles for doors and windows: start with materials 1. Thickness: aluminum alloy sliding doors are available in 70 series and 90 series. The 70 series can be used for alloy sliding doors. The series number represents the number of millimeters in the thickness of the door frame. There are four types of aluminum alloy sliding windows: 55 series, 60 series, 70 series and 90 series. The selection of the series should be based on the size of the window and the local wind pressure. The aluminum alloy sliding window used as a closed balcony should not be less than 70 series.  2. Strength: The tensile strength should reach 157 Newtons per square millimeter, and the yield strength should reach 108 Newtons per square millimeter. When purchasing, you can bend the profile moderately with your hands, and the profile should be restored after letting go.  3. Chroma: The color of the same aluminum alloy profile should be the same. If the color difference is obvious, it is not suitable for purchase.   4. Flatness: Check the surface of the aluminum alloy profile, there should be no depression or bulging.  5. Glossiness: Avoid choosing profiles with open bubbles (white spots) and slag (black spots) on the surface of aluminum alloy doors and windows, as well as obvious defects such as cracks, burrs, and peeling.  6. u200bu200bDegree of oxidation: The thickness of the oxide film should reach 10 microns. When purchasing, you can swipe lightly on the surface of the profile to see if the oxide film on the surface can be wiped off.
