GTFI Industrial Alliance

Our Industrial Foundation & Manufacturing Network

In the 1960s, China launched the Third Front Construction, a major national industrial strategic initiative. A vast network of manufacturing, heavy processing, and precision component production facilities was established across the inland regions of Southwest, Northwest, and Central China, laying a solid industrial foundation for the country's modern heavy industry system.

Today, our alliance brings together dozens of these factories, carrying forward decades of machining heritage to serve global industries with precision, reliability, and integrity.
