product description:
Features:
1. Stable performance: The grouting filling method does not apply any external force and heat to the steel bar, so it will not cause the expansion and contraction of the steel bar or generate residual stress;
2. Support customization: complete specifications, a large number of stock, can process customized products according to the needs of various departments with drawings and samples;
3. Standard process: the thread profile is good, the production is excellent, and the steel bar link strength is high.
