In an era of rapidly evolving infrastructure demands, geotechnical engineers face increasing challenges from unstable soils, deep excavations, and high-load requirements in projects ranging from urban skyscrapers to coastal defenses. Addressing these needs, SupAnchor, Asia's leading manufacturer and exporter of self-drilling anchors, has launched the SupUTS self-drilling hollow anchor. This innovative product leverages the brand's expertise to offer enhanced performance and reliability, positioning itself as a key solution for heavy-duty engineering scenarios across Europe and America.

The SupUTS series builds on SupAnchor's proven self-drilling anchor system, which integrates drilling, grouting, and reinforcement into a single hollow bar. This drill-and-grout bolt approach streamlines construction by eliminating the need for separate equipment, making it ideal for challenging ground conditions. Key features include:
The table below summarizes key technical data for select models, highlighting how these specs address engineering challenges:
| Model | Outside Diameter (mm) | Ultimate Load (kN) | Yield Load (kN) | Weight (kg/m) | Typical Applications |
|---|---|---|---|---|---|
| SSTR32/360 | 32 | ≥360 | ≥280 | 3.5-4.0 | Deep foundation reinforcement, moderate load projects |
| SSTR38/660 | 38 | ≥660 | ≥520 | 6.3-6.8 | Heavy-duty tunnel support, slope stabilization |
| SSTR51/930 | 51 | ≥930 | ≥730 | 9.0-9.5 | Extreme load scenarios, large-scale infrastructure |
This geotechnical reinforcement system excels in unconsolidated or cohesive soils, where traditional methods are inefficient. The hollow bar anchor design maximizes bonding with grouting materials, while the rib structure reduces soil splitting forces, ensuring structural stability with crack widths below 0.1 mm at maximum load.
The SupUTS self-drilling anchor bolt is well-suited for a variety of demanding projects, demonstrating its versatility and market value. Key application scenarios include:
By addressing these needs, the self drilling anchor system enhances safety and efficiency, reducing risks associated with ground instability and high loads.
The introduction of the SupUTS series aligns with global trends in infrastructure development, where geotechnical safety and project timelines are paramount. In sectors like tunneling, mining, and large-scale construction, this hollow bar anchor technology offers:
This makes the SupUTS a valuable asset for engineers and contractors worldwide, fostering resilience in critical infrastructure projects.
SupAnchor's commitment to professionalism, innovation, and collaboration is evident in the SupUTS series. As the No. 1 manufacturer and exporter of self-drilling anchors in Asia, the brand leverages extensive R&D and holds ISO certifications to ensure product quality and performance. Key aspects include:
