The single biggest source of order errors is a vague specification. Use this checklist when you send us your requirements.




These are the failures we see most often in formwork fastener imports, and the controls we build into every order to stop them.
Our control: CNC cutting with 100% gauge checks; a dimensional report is sent before shipment.
Our control: BOM-based kit packing. Every case is marked to your drawing, so the crew matches parts in minutes.
Our control: CNC thread rolling plus go / no-go gauge inspection on every batch.
Our control: Salt-spray tested finishes, with a batch coating report included in the shipment.
Our control: Raw material stock and a weekly production plan shared with key accounts.
Our control: Seaworthy export packing: pallet, steel strapping, waterproof wrap, and container loading photos.
Procurement decisions get easier when every step is predictable. This is exactly how every Qianheng order runs.
