core advantage

Ultra-high strength and long-term protection

Selecting high-quality high-carbon steel as the base material and combining it with precision multi-stage drawing processes, the bead steel wireachieves a tensile strength of 2800-3200 MPa, far exceeding industry standards, ensuring structural stability under heavy loads, high speeds, and extreme pressure conditions. Using fully automatic bronze/copper plating technology, the coating uniformity is precisely controlled at ±0.5g/kg, forming a dense anti-oxidation protective layer. Compared to traditional methods, this increases the service life by 40%, effectively resisting external environmental erosion.

Flexible customization and global adaptation

Provide 0.89mm-1.65mm full-diameter custom services, integrating over 20 process options such as pre-applied adhesive treatment and special alloy coating to meet the differentiated needs of various tire types. Strictly adhere to international standards like ETRTO (European Tire Technology Organization), TRA (Tire Association of America), and JATMA (Japan Association of Tire Manufacturers) to ensure the product's universality and compliance in the global market.

Zero defect quality assurance system

Through the IATF 16949 automotive industry quality management system certification, a full-process intelligent monitoring network has been established. Using a laser diameter gauge (precision ±0.001mm) to detect diameter deviations in real time, combined with an online eddy current testing system, millisecond-level response detection of internal defects in steel wires is achieved, ensuring a product defect rate below 0.02%. This provides customers with a stable and reliable quality commitment.
