BY series of grouting material widely used in plant structure, mechanical equipment, electrical equipment installation, maintenance repair work, installation of port rail grouting, and a variety of concrete reinforcement, waterproof plugging and highway repair.

Products have been registered "BY" trademark, more than a decade, BY series of grouting material has been successfully applied to a number of major and major projects, such as Baoshan Iron and Steel II, Phase III; Nuclear Power Station II, Phase III; WISCO two hot-rolled plates Factory; Shanghai Pudong International Exhibition Center; Shanghai GM; Shanghai Waigaoqiao Terminal Expansion Project; Shanghai Han Sung Paper; town Jiang Jindong Paper; Xiamen International Exhibition Centre. Involved in metallurgy, paper, power, ports, civil, chemical and other industries, with its excellent quality received by users, has been in the field of play more and more a strong influence.
