It is adjacent to the Shanghai-Nanjing Expressway and the Yangtze River Coastal Expressway, offering extremely convenient transportation.

It is a major FRP raw material base in China, known for its large output, high quality, diverse varieties, and extensive product coverage. The company serves as a council member of the China Fiberglass Industry Association and the China Composites Industry Association, as well as the chair unit of the China Unsaturated Polyester Resin Industry Association.

The company primarily produces unsaturated polyester resin (UP), gel coat resin and auxiliary materials, vinyl ester resin, fiberglass products, FRP products, fiberglass adhesives and emulsions, acrylic resin, and hydroxy esters, among others. Its products are sold both domestically and internationally. In recent years, the company has continuously explored new application areas, developing new products for infrastructure construction such as highways, railways, rail transit, lead-selection hydroelectric and wind power, architectural decoration, and sanitary facilities, thereby building a new development platform.

After over six decades of development and independent innovation, Tianma Group has consistently maintained a leadership position in the highly competitive market. It has evolved into an enterprise group with comprehensive functions including scientific research and development, production and operation, material circulation, talent training, and information services. It remains one of China's largest, highest-quality, most diverse, and widely covering FRP raw material industrial bases.
