宽度可调式金属 U 型槽钢衬里型材轧制机

钢衬里的作用是什么？哪些情况下必须安装钢衬里？

1. Doors and windows in buildings must withstand environmental influences, mainly wind pressure and rain and snow invasion, as well as the switching force and self gravity during use.
2. Wind force is the main cause of bending and deformation of door and window components (such as horizontal bars, mullions, and window frames), as well as frames and sashes. The safety of doors and windows mainly depends on their ability to withstand wind force, usually measured by the gas pressure value they bear per unit area.
3. The mechanical properties of hard PVC plastic are far inferior to those of steel, aluminum, and wood, especially the bending strength of hard PVC plastic is only 1/4 of that of wood, 1/28 of that of aluminum, and 1/84 of that of steel. Under the same cross-sectional shape and size as aluminum and steel profiles, the bending performance of hard PVC plastic profiles is much worse.
4. To compensate for this disadvantage, the cross-sectional dimensions of the hard PVC profiles used for making doors and windows are designed to be larger than those of steel and aluminum door and window profiles.
5. At the same time, the mechanical properties of its cross-sectional shape should be as reasonable as possible to meet the stress conditions of doors and windows.
6. The above methods cannot fully meet the mechanical performance requirements of doors and windows.
7. Another important measure is to add steel reinforced steel, also known as steel lining, to the cavity of PVC plastic profiles when a single profile of doors and windows exceeds a certain length.
