The Laboratory for testing window & door profile and decorated materials is a national grade laboratory which specializes in testing plastics profile, plastic window & door, parts of window & door and decorated materials, and the laboratory is a branch of the national chemical construction materials testing center. In recent years, with the support of national science and technology department, SINOPEC and BRICI, the laboratory has developed as a Laboratory for testing window & door profile and decorated materials that has self-contained testing means, has great authority and is very specialized.
The laboratory has tested and evaluated the properties of raw materials products and semi-products for various domestic brands and overseas brands, such as Wuhu Conch, Dalian Shide, BNBM, Anhui Guofeng, Zhejiang Zhongcai, Changzhou Chuangjia, Tianjin Jinpeng, Xinjiang Tunhe, Yunnan Hongta, Guangdong Gudi, Dalian Ykk, Shanghai VEKA, Tianjin COMMERLING, GE, Dupont( the arrangement is random).
The main equipments in the laboratory are introduced overseas. Whole door and whole window test equipment can do experiments of high grade wind pressure, dynamic pressure etc.; the Xeon lamp weather aging has 500 locations; and also the laboratory has equipped environmental experiment equipments such as UV, FOG, Ozone etc. to provide specialized service for users.
The laboratory is a place for transacting and checking door & window license designated by General Administration of Quality Supervision , Inspection and Quarantine of the People's Republic of China.
