Lizhong Precision — Tangshan, China

About Us

One-stop fabrication.
Unmatched breadth.

Founded in 2017 and backed by Jiayuan Group (est. 1996), Lizhong Precision is a 40,000 m² heavy fabrication company in Tangshan, Hebei — China's steel heartland. With RMB 50 million registered capital and 166 specialists, we deliver complete part families from raw steel to ready-to-install components.

As a strategic steel procurement partner of HBIS Group and Shougang Steel, we source premium medium/heavy plate and structural steel at preferred pricing — and pass those savings through to our customers' BOM cost.

Our proprietary MES digital system (software patent), paired with a 12-person QC team and on-site CMM, ensures every order is traceable from incoming material to final delivery inspection.
