Door and window equipment is the equipment used by door and window enterprises in the production of doors and windows. Doors and windows play an important role in a building.
China's modern architecture doors and windows developed in the twentieth century. Metal doors and windows represented by steel doors and windows have a history of 90 years in our country. However, the golden age of the development of Chinese contemporary architecture doors and windows was two decades from 1981 to 2001. In 1911, steel doors and windows were introduced to China, mainly products from Britain, Belgium, and Japan, concentrated in the "rental land" of coastal port cities such as Shanghai, Guangzhou, Tianjin, and Dalian. In 1925, China's Shanghai National Industry began small-scale production of steel doors and windows. Before the founding of New China, there were only more than 20 small workshop-type handicraft factories. After the founding of new China, steel door and window companies in Shanghai, Beijing, Xi'an and other places have established large steel door and window production bases, which have been widely used in industrial construction and some civil engineering.
In the late 1970s, the country vigorously implemented the resource allocation policy of "replacing wood with steel", and a nationwide upsurge in the promotion of steel doors and windows, steel scaffolding, and steel formwork has greatly promoted the development of steel doors and windows.
The 1980s was the heyday of traditional steel doors and windows, and the market share once reached 70%. Aluminum alloy doors and windows were introduced to China in the 1970s, but they were only used in foreign embassies and a few foreign-related projects. With the in-depth development of the national economic governance and its achievements, the aluminum doors and windows series have also developed from 4 varieties and 8 series in the early 1980s to more than 40 varieties and more than 200 series, forming more developed aluminum doors and windows products. The system established the pillar product status.
