In the realm of geotechnical engineering, where challenging soils and heavy loads demand robust solutions, SupAnchor has unveiled its latest innovation: the Grade 75 self-drilling hollow anchor. As the No.1 manufacturer and exporter of self-drilling anchors in Asia, SupAnchor addresses the growing need for enhanced load-bearing capacity in projects ranging from deep foundations to tunnel support, offering a product that combines high strength with efficient installation.
This new variant is part of SupAnchor's comprehensive self-drilling anchor system, which leverages a proven "3-in-1 principle" integrating a sacrificial drilling rod, injection tube, and reinforcing bar into a single hollow bar. By utilizing Grade 75 high-strength steel, this anchor is tailored for applications where standard-grade anchors fall short, such as in heavy-load infrastructure or unstable geological conditions. For engineers and project managers across Europe and America, this development signifies a leap forward in geotechnical reinforcement systems, promising improved safety and efficiency.
The Grade 75 self-drilling hollow anchor builds on SupAnchor's established design logic, with key technical features that address common engineering challenges. Its high-strength material foundation ensures superior tensile and yield loads, while the standardized thread and rib design facilitate quick on-site connections and optimal bonding with grouting materials. This geotechnical reinforcement system is particularly effective in unconsolidated or cohesive soils, where traditional drilling methods are inefficient and risky.
To illustrate the specifications, inferred technical data for common models based on SupAnchor's product line logic are summarized below. These parameters highlight how the self drilling anchor bolt meets the demands of heavy-duty projects.
| Parameter | R32 Model (Inferred) | R38 Model (Inferred) |
|---|---|---|
| Outside Diameter (mm) | 32 | 38 |
| Ultimate Load (kN) | ≥380-420 | ≥550-600 |
| Yield Load (kN) | ≥300-340 | ≥440-480 |
| Material Grade | Grade 75 High-Strength Steel | Grade 75 High-Strength Steel |
| Thread Type | ISO 10208 - R32 | ISO 10208 - R38 |
These specs enable the anchor to withstand extreme forces, reducing the risk of deformation or failure in critical structures. For example, in deep foundation reinforcement or tunnel excavation, the high load-bearing capacity ensures stability even under high soil pressure. Additionally, compatibility with anti-corrosion treatments like hot-dip galvanizing allows use in moderately corrosive environments, expanding the application scope of this drill-and-grout bolt.
The Grade 75 hollow bar anchor is designed for a range of demanding projects. Key application scenarios include:
