Q:How do you guarantee the quality of high-strength bolts like A193 B7?

A: Quality is our lifeline. We have implemented a full-process MES digital quality traceability system. Each bolt is assigned a unique QR code linked to its specific Heat Number, ensuring 100% material accuracy from raw steel to finished product. Our facility is ISO 9001:2015 certified , and every batch undergoes rigorous testing (tensile, yield, hardness, and salt spray) in our CNAS-standard laboratory.
