The company's main products include chemical anchor bolts, mechanical anchor bolts, inverted cone anchor bolts, post-expanded bottom mechanical anchor bolts, subway segment bolts, precast components, and other series.

DUOGU® established a 11,000-ton anchor bolt production base in North China in 2018, fully funded by Shanghai DUOGU Company, to meet domestic and international order demands.
