Description

Steel-plastic composite profile and manufacturing method thereof

The invention relates to a structural member and a building material in the field of construction, in particular to a steel of a series of push-pull or casement doors and windows of a composite profile device which is formed by combining a steel profile and a plastic profile to form a composite profile. Plastic composite profile material, steel-plastic composite profile device and manufacturing method thereof.

At present, fixed or mobile closing devices, such as doors, windows, sunshade devices, gates, etc., which are used in openings of buildings, vehicles, fences or similar enclosures, especially in the structures of doors and windows of buildings, because With the improvement of living environment and living standards, people have higher and higher requirements for doors and windows, and related industries have also continuously developed various types of door and window products in response to market needs.

From the perspective of the existing door and window structure of building structural components, the structure has been changed at many different levels. The earliest designed doors and windows such as traditional plastic profiled windows and doors are widely used. Compared with traditional steel windows and wooden window structures, the doors and windows have better sealing and thermal insulation, but they have the defect of low structural strength. In this way, the door and window components are worn or deformed after a period of use, and It needs to be replaced, causing inconvenience to users and maintenance personnel.

In recent years, steel-plastic composite doors and windows composed of plastic profiles and steel profiles have been developed. Compared with traditional steel doors and windows and wooden doors and windows, the new structure of steel-plastic composite doors and windows does have a seal.
