R&D Center

As one of the main science research and development branches of China Construction Ministry, Hongtai Industry Group Company has always been focused on research and development of aluminium composite panels. To ensure the quality of the raw materials and finished products, we import advanced testing equipment from the USA, German and Japan. All our products have undergone a series of tests, which include 180．peeling strength, dynamic characteristics of raw materials, color difference, salt-spray corrosion resistance, boiling water resistance, finished coating thickness, impact resistance, gloss test etc. Consequently, you can feel secure in knowing that the quality of ALUTILE panels is guaranteed.
