Plastic profiles are used for the production

Plastic profiles are used for the production of doors and windows with PVC profiles, as early as the late 1950s has been in Germany, China began in 1983, began in the late 1990s began universal application. Because the simple use of PVC profiles of the doors and windows of the strength is not enough, usually in the cavity to add steel to enhance the stability of doors and windows, so the profile of steel interior made of plastic doors and windows are often called steel doors and windows. With the extensive use of steel doors and windows, PVC profiles for the production of steel doors and windows are commonly known as steel profiles. Plastic steel is also used as a common material for the fence. Composition structuresliding plastic pvc profile for windows and doors Plastic profiles are made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain percentage of stabilizers, colorants, fillers, UV absorbers, etc., by extrusion of the profile. Ordinary steel profiles will be deformed, the color is relatively monotonous, usually white, if you want to change the color will add PVC film, a long time the PVC film will fade. Automotive supplies industry in the use of steel, the material requirements are relatively high, the most typical is the engine chassis protection board, has been widely used by most riders.

Plastic steel cage with: 1, reduce the friction and roller slip, reduce the working temperature; 2, to improve safety and performance; 3, fail safe mode, not stuck.
