Steel windows were introduced to China in the early 19th century and China began to produce steel windows in 1925; aluminum profiles were introduced to China in the 1970s, and in 1980 China began to produce aluminum profiles for aluminum doors and windows.
1. Doors and windows-Chinese traditional doors and windows are wooden doors and windows
Steel windows were introduced to China in the early 19th century and China began to produce steel windows in 1925; aluminum profiles were introduced to China in the 1970s, and in 1980 China began to produce aluminum profiles for aluminum doors and windows.
Aluminum profile doors and windows were first used by foreign embassies (consulates) in China in the 1970s and a few foreign-related projects. In 1978, Shanghai Glass Machinery Factory was the first to develop and manufacture aluminum doors and windows in China and won the National Science and Technology Award.

2.Insulated aluminum window
In 1984, the first use of insulated aluminum profile windows in China, North China Aluminum Co., Ltd. ALUK cooperated to complete the Beijing International Hotel and Tianjin Binhai Building, the earliest applications of insulated aluminum windows in China.
Aluminium Profile doors, windows, and building curtain walls were quickly accepted and favored by the Chinese construction industry. They were widely used. From the mid-1980s to the 1990s, China entered the climax of aluminum doors and windows. Development, prosperity and progress, especially aluminum profiles for construction.
In recent years, Aluminium Profile System China has become more and more active in the market, and its output has also increased with the use of people. It has gradually surpassed many countries. It can be seen that this material has good performance and is widely used throughout the world. In recent years, China ’s calls for environmental protection and energy-saving are getting higher and higher. Products that meet this requirement can be recognized by everyone. Therefore, manufacturers of aluminum profiles in China pay more attention to environmental protection and energy conservation. Everyone develops in this direction and makes aluminum profiles a life.

Industrial aluminum profiles are classified according to surface treatment requirements
Industrial aluminum profiles have many advantages and can solve a series of problems that people encounter in life. Everyone can find industrial aluminum profiles in the surrounding environment of their lives at any time, which is exactly why. In fact, in order to meet the functional requirements of various types of construction and articles, the aluminum profiles in our lives will undergo relevant changes, and different types of industrial aluminum profiles will be used. Next, we will learn more about this together.
Industrial aluminum profiles are classified according to surface treatment requirements:
1. Anodized aluminum
2. Electrophoretic coating aluminum
3. Powder coated aluminum
4. Wood grain transfer aluminum
5. Planed aluminum (divided into mechanical planing and chemical polishing, of which chemical polishing has the highest cost and the most expensive)
The arc surface of most industrial aluminum alloy profiles is of high surface requirements. Due to the characteristics of astigmatism, the badness of the arc surface can be clearly reflected!
