In an era where geotechnical engineering faces unprecedented challenges—from unstable soils in urban expansions to extreme load demands in mega-infrastructure—the need for robust, efficient solutions has never been greater. 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 system. This product is engineered to address complex scenarios where traditional anchors fall short, combining high-strength performance with streamlined installation to enhance safety and reliability in projects worldwide.

The SupUTS series builds on SupAnchor's proven self drilling anchor system, featuring a 3-in-1 integration principle that merges drilling, grouting, and reinforcement into a single ribbed hollow steel bar. This design eliminates the need for separate casing and injection equipment, significantly reducing construction time and labor costs—especially critical in unconsolidated or cohesive soils. Key parameters, such as enhanced ultimate tensile strength (UTS), make this hollow bar anchor ideal for high-load applications, from deep foundations to tunnel supports.
Below is a summary of technical data for select models, highlighting core specifications that solve engineering challenges:
| Model | Outside Diameter (mm) | Ultimate Load (kN) | Yield Load (kN) | Weight (kg/m) | Anti-Corrosion Options |
|---|---|---|---|---|---|
| SSTR32/360 | 32 | ≥360 | ≥280 | 3.5-4.0 | Hot-dip galvanizing, SupCoating, Stainless steel |
| SSTR38/660 | 38 | ≥660 | ≥520 | 6.3-6.8 | Hot-dip galvanizing, SupCoating, Stainless steel |
| SSTR51/930 | 51 | ≥930 | ≥730 | 9.0-9.5 | Hot-dip galvanizing, SupCoating, Stainless steel |
This geotechnical reinforcement system excels in demanding environments by offering customizable anti-corrosion treatments—hot-dip galvanizing for general use, SupCoating for moderate corrosion, and stainless steel for harsh conditions—ensuring longevity in projects like coastal defenses or industrial zones. The drill-and-grout bolt functionality minimizes soil disturbance, while standardized thread compatibility accelerates on-site assembly, addressing common inefficiencies in traditional methods.
The SupUTS self drilling anchor bolt is tailored for a range of high-stakes applications, leveraging its high-strength design to enhance global infrastructure safety. Key scenarios include:
