Yidao Quality Control: Multi-Sample Tensile Testing Ensures System Safety
At Yidao, quality control goes beyond component inspection—we verify the complete system. Our QC team recently conducted a multi-sample tensile test on Dia15mm hot-rolled formwork tie rods assembled with customer-supplied wing nuts and hex nuts.
Testing the Complete Assembly
Five tie rod assemblies were tested side by side to measure the ultimate breaking load of the full system—bar, nut working together. This method reflects real on-site loading conditions, rather than testing individual materials in isolation.

Reducing Real Risks on Site
A mismatch between bar and nut can lead to thread stripping, brittle fracture, or sudden failure under high tension. For contractors and project managers, that could mean formwork collapse, costly delays, or risk to workers on site. By testing multiple assembled samples, we confirm that each batch meets the required load capacity before shipment.
Safety You Can Verify
For our customers, this means reliable system performance, documented test results, and full batch traceability. Whether you purchase complete assemblies or supply your own accessories, Yidao validates the entire configuration to protect your project and your people.
