Laboratory for testing windows & doors,building curtain walls and energy conservation productsis a national grade laboratory professionally engaging in testing and studying the performance of plastic profiles,
aluminium profiles,windows & doors and parts of them ,building curtain walls,energy conservation products,and decorated materials. Now it has been equipped by the most advanced testing system so as to become a famous lab studying on the testing and evaluation of the windows & doors ,building curtain walls and energy conservation products in China.
　　 The laboratory has tested and evaluated the properties for raw materials,products and semi- products.Our customers include domestic manufacture and overseas companies,such as Wuhu Conch,Dalian Shide,BNBM,Anhui Guofeng,Zhejiang Zhongcai,Changzhou Chuangjia,Tianjin Jinpeg,Xinjiang Tunhe,Yunnan Hongta,Guangdong Gudi,Dalian YKK,Shanghai Veka,Tianjin COMMERLING,GE,Dupont,etc.(the arrangement is random).

　　The main equipments in the laboratory are provided by famous manufactures all over the world.
Doors and windows test equipment can do experiments of high grade wind pressure,dynamic pressure etc.The Xeon lamp weather aging can do over 300 samples at the same time.And also the laboratory has equipped other aging equipments such as UV,FOG,Ozone etc.

　　Our reports are recognized by customer and China government.And also we can issue reports in English according to customers`and overseas certification bodies`requirements.
