How to choose the doors and windows of steel structure houses?

Advantages of steel structure houses 1. The steel structure is light in weight and high in strength. The weight of the house built with steel structure is about 1/2 of that of the reinforced concrete house; it can meet the needs of the large room of the house, and the usable area is about 4% higher than that of the reinforced concrete house. 2. It has good seismic performance, and its ductility is better than that of reinforced concrete. Judging from the post-earthquake survey results at home and abroad, the number of steel-structured residential buildings collapsed was small. 3. The steel structure components are made in the factory, which reduces the workload on site, shortens the construction period, and meets the requirements of industrialization. 4. The steel structure factory has reliable production quality, accurate size, convenient installation, and easy to cooperate with related parts. 5. Steel can be recycled, and there is less environmental pollution during construction and demolition. How to choose windows for steel structures: At present, most houses have large windows (such as closed balconies) and many high-rise buildings. Therefore, when choosing plastic-steel profiles, the state stipulates that the wall thickness of plastic-steel profiles should be greater than 2.5 mm. Pay attention to plastic-steel doors and windows. The wall thickness of the profiles is qualified, whether there are obvious scratches on the profiles, whether there are cracks at the welding corners, etc., whether the cleaning corners are symmetrical, etc. Whether there is a multi-cavity structure, there is a drainage cavity, an isolation cavity, and a reinforcement cavity, which can ensure that the window is not easy to deform and age. Secondly, hardware accessories should choose accessories with excellent performance and sensitive switches. Excellent plastic steel doors and windows should be combined with window design, so that residents can be more comfortable. For example, facing the noisy residential area in the downtown area, you can choose plastic steel casement windows with insulating glass, which have excellent sealing, thermal insulation and sound insulation effects. For another example, from the perspective of the design hardness of the window type, the corresponding window type can be designed according to the corresponding requirements. When designing the window type, the principles of performance, applicability and aesthetics should be taken into consideration. For example, outside casement windows should be used in the study and living room, sliding windows should be used for sealing balconies, and inward opening and inner inverted windows should be used in bedrooms. Window is an important part of a building. It should have the same long life as the building. Choosing a good door and window is also a good guarantee for living quality. Choose a window type suitable for space design: There are many types of window types, and they are not the same in terms of design performance and characteristics. When choosing, they should be properly matched according to their needs, which is also the main link to save costs. Casement window: Wide range of use, divided into two types: external opening and internal opening. The inner closed is easy to clean the window, but when it is opened, it takes up indoor space, it is easy to meet, and it will leak inward in rainy days. The window sash that opens outwards has good waterproof function and does not occupy indoor space when closed, but it is easily damaged in strong wind and rainy days, and requires higher strength of hardware. The biggest feature of casement windows is air tightness and good sealing, the sash can be fully opened, which is convenient for ventilation, and the structure is easy; the disadvantage is that the hardware is more profitable and more expensive. Sliding windows: Sliding windows have the advantage of not occupying indoor space, with beautiful appearance, economical price and general sealing. Adopt high-grade slide rail, push it slightly, and it can be closed sensitively. Coupled with large pieces of glass, it not only increases indoor lighting, but also improves the overall appearance of the building. But the ventilation area is limited.
