In the face of increasingly complex geotechnical challenges, from unstable soil in deep urban excavations to harsh coastal environments for infrastructure projects, engineers are demanding higher performance from anchoring solutions. SupAnchor, recognized as Asia's leading manufacturer and exporter of self-drilling anchors, has responded with the launch of the SupUTS self-drilling hollow anchor. This product is engineered to deliver enhanced load capacity and reliability for demanding applications, reinforcing the brand's commitment to innovation in the geotechnical reinforcement system market.

The SupUTS series builds on SupAnchor's proven self drilling anchor system, incorporating a 3-in-1 integration principle that combines drilling, grouting, and load-bearing into a single ribbed hollow steel bar. This design streamlines on-site processes, reducing construction time and risks in unconsolidated or cohesive soils. Key specifications, such as high ultimate tensile strength (UTS), standardized threading, and flexible anti-corrosion options, address critical engineering needs.
To illustrate, here are the technical data for key models in the SupUTS series:
| Model | Outside Diameter (mm) | Ultimate Load (kN) | Yield Load (kN, inferred) | Anti-Corrosion Options |
|---|---|---|---|---|
| SSTR32/360 | 32 | ≥360 | ≥280 | Hot-dip galvanizing, SupCoating, Stainless steel |
| SSTR38/660 | 38 | ≥660 | ≥520 | Hot-dip galvanizing, SupCoating, Stainless steel |
| SSTR51/930 | 51 | ≥930 | ≥730 | Hot-dip galvanizing, SupCoating, Stainless steel |
These parameters enable the SupUTS anchor to solve engineering challenges such as deep foundation reinforcement for high-rise buildings, where traditional anchors may lack sufficient tensile strength. The ribbed design optimizes bonding with grout, while the 45° angled rib surfaces minimize soil disturbance, ensuring structural stability with crack widths below 0.1 mm at maximum load. This makes the SupUTS a robust geotechnical reinforcement system for critical projects.
The SupUTS self-drilling anchor bolt is particularly suited for heavy-duty scenarios, including:
This versatility enhances global infrastructure development by providing reliable ground anchor bolt solutions that mitigate risks in geotechnical engineering. For instance, in large-scale projects like bridge foundations or industrial plants, the efficient drill-and-grout bolt installation reduces labor intensity and project delays, contributing to overall cost-effectiveness and safety standards.
SupAnchor's introduction of the SupUTS series underscores its position as a professional and innovative leader in the self drilling anchor system market. With ISO certifications and a strong R&D focus, the company has developed products that meet international standards for thread design and material quality, such as high-strength steel grades per EN10083-3. This ensures compatibility with a wide range of accessories, promoting collaborative engineering solutions across global projects from Europe to the Americas.
The brand's message of professionalism, innovation, and collaboration is evident in its tailored anti-corrosion strategies—from hot-dip galvanizing for general use to SupCoating and stainless steel for harsh environments—which extend service life and adapt to diverse site conditions. By addressing the evolving needs of soil nail system manufacturers and ground anchor bolt factories, SupAnchor continues to drive advancements in geotechnical safety and efficiency.
