T30 Self-Drilling Anchor Bolt
Advantages:
1.Lightweight and Fast Installation: Designed for easy handling and rapid ground support. The small-diameter, lightweight anchor bars are easier to transport, handle, cut, and install, allowing for dense anchor placement on site when required.
2.Excellent Equipment Compatibility: No large drilling rigs are required. Compact drilling equipment can be used for direct drilling and installation, making the system highly adaptable to narrow working areas, confined urban excavations, and restricted slope sites. This effectively overcomes the challenges of limited access and insufficient working space.
