We are a factory-direct manufacturer of formwork fastening systems, producing tie rods, water-stop tie rods, nuts, plates and accessories in our own facility. Buying direct removes the trading margin and lets us adjust dimensions and surface treatment to your project.
Factory & Quality Control
See the machines, the checks and the packing behind every Qianheng order.
Material stock keeps your lead time short
We keep raw material stock for common grades, so production starts the day your sample is approved, not the day the steel arrives.
Factory visits and video calls are welcome. Book a tour and see the lines in person.
