Once upon a time, steel doors and windows were extremely popular in Europe and the United States. The ancient buildings of the Shanghai Bund, known as the “International Architecture Expositionâ€, are mainly made of steel. More than 100 years have passed. With the changes in concepts and consciousness, people's requirements for architecture have long gone beyond the scope of their original use. Modeling and color matching have become themes. The window is the eye of the building, and it is the finishing touch to the building with its decorative effect. Therefore, the color matching of doors, windows and buildings has become a subject in the contemporary environmental art field, which has also made color doors and windows more and more popular.
Aluminum-plastic composite doors and windows have been used in the construction market in Europe and America since the 1970s. As a high-end product, it was adopted by many famous buildings. Such as the German SBMW Building, Hanover University, the British Business Center, the European Hotel in the Netherlands, the GreatBelt Bridge in Denmark. Since the 1980s, due to a series of technical problems such as color grading, powder recycling, and electrostatic voltage, its manufacturing costs have been greatly reduced. Due to the invention of thermosetting resin, it also extended its gloss and color retention period to more than 20 years. Therefore, powder-sprayed colored aluminum doors and windows have been explosively developed in Europe and the United States. By the end of the 1980s, its market share had exceeded 40%. A variety of building developers have adopted powder-coated, colored aluminum doors and windows to give buildings a new life, such as the Barcelona Airport and the Ocean Center, which was built in 1992 to welcome the Olympic Games in Barceloneta. A series of buildings such as the Color TV Center, the Olympic Sports Center, etc. all use colourful powder-coated colored aluminum profiles. Another example is Paris, France, in the reconstruction of Charles de Gaulle airport, all interior and exterior halls, elevator access, all kinds of signs are all using different colors of powder coating color aluminum, so that people who have been there left a deep impression.
Powder-sprayed colored aluminum doors and windows have become the mainstream in the field of construction doors and windows in Europe and America because of their rich color, natural lubrication, corrosion resistance, stain resistance, and weather resistance. According to the authoritative prediction of international architecture, it still shows a strong increase in the 21st century.
