Since 1995, the national aluminum doors and windows curtain wall industry annual conference and aluminum doors and windows curtain wall New Product Expo has been successfully held for 17 times, and has grown together with the industry of doors and windows curtain wall. In 2011, it won the honor of "top 3 exhibition of 40 industries in the world". As the most influential and large-scale professional business exhibition platform in the industry, the Expo provides a strong innovation impetus for the rapid and diversified development of the global aluminum doors, windows and curtain wall industry.

The 18th door and window curtain wall Expo in 2012 consists of four exhibition halls and six exhibition areas, with an exhibition area of more than 45000 square meters. Among them, the door and window hardware exhibition area has gathered more than 100 well-known domestic and foreign enterprises, including norto, Huiyu, Assa Abloy, Italy Savio, bonalijin, Taiwan, Jianlang, Lixing, Tianbian and Dongtian, Ningbo , Zhejiang Dongge and many other foreign and domestic hardware giants.

With the industry market becoming more and more mature, the competition pattern of relying on the price advantage to win in the past has quietly changed. Most enterprises are strongly aware that the modern market competition requires higher technology content of door and window hardware accessories, and the competition of door and window hardware industry "wins" in technology.

In order to ensure the excellent properties of doors and windows, the high-grade hardware accessories of doors and windows are basically manufactured by the process of precision mold and high automation. The materials are mainly stainless steel, aluminum alloy, zinc alloy and high-quality engineering plastics on the premise of meeting the strength. Some manufacturers in the market blindly save costs, change materials and configuration at will, leaving serious security risks for the installation of doors and windows. Such production enterprises will be eliminated gradually in the modern market focusing on quality.

The quality of doors and windows is determined by a series of complete quality assurance systems. In the production of doors and windows, we should attach importance to the systematic engineering of each production link, and fundamentally change the previous neglect of the quality of hardware accessories. With people's constant pursuit of higher quality and higher grade doors and windows, the door and window hardware accessories that pay attention to technology will usher in a broader development space.

So what kind of conditions should the high-quality hardware fittings of doors and windows meet? In addition to the physical and mechanical properties of doors and windows, what other properties should they have?

From March 18 to 20, 2012, the top hardware manufacturer of doors, windows and curtain walls from all over the world will jointly uncover the mystery for us in Guangzhou Poly world trade exhibition hall, and present the latest technology display and new product release for the industry, with annual expectation!
