In coastal regions, chemical plants, and underground tunnels, engineers grapple with the relentless threat of corrosion that can compromise structural integrity. SupAnchor, Asia's premier manufacturer and exporter of self-drilling anchors, has responded with a groundbreaking innovation: the Stainless Steel Self-Drilling Hollow Anchor. This product is designed to tackle high-corrosion challenges while maintaining the efficiency and reliability of the self drilling anchor system, marking a significant leap in geotechnical reinforcement technology for European and American markets.
The new anchor adheres to SupAnchor's proven "3-in-1 principle," which integrates sacrificial drilling rod, injection tube, and reinforcing bar into a single, streamlined component. This design eliminates the need for separate casing systems, enabling simultaneous drilling and grouting in unconsolidated or cohesive soils. Made from high-grade stainless steel, the anchor offers inherent resistance to rust, pitting, and degradation from moisture, saltwater, industrial chemicals, and harsh weather, ensuring long-term performance where standard carbon steel anchors might fail.
Key technical parameters from the R32SS/15 model illustrate its robust capabilities:
| Parameter | Value |
|---|---|
| Outside Diameter (mm) | 32 |
| Internal Diameter (mm) | 14 |
| Cross Sectional Area (mm²) | 509 |
| Ultimate Load (kN) | ≥405 |
| Yield Load (kN) | ≥300 |
| Weight (kg/m) | 4.00 |
| Thread Type | ISO 10208 - R32 / Left or Right |
| Steel Type | Stainless Steel |
| Elongation % | A100mm ≥6% / Agt ≥5% / A200mm ≥6% |
These specifications ensure that the hollow bar anchor not only excels in corrosion resistance but also retains superior mechanical properties, such as tensile strength and yield load, comparable to or exceeding standard carbon steel models. The optimized rib structure, with a relative rib area of 0.21 to 0.33, maximizes bonding with grouting materials and reduces splitting forces on surrounding soil or rock, keeping crack widths below 0.1 mm at maximum load. This drill-and-grout bolt system simplifies on-site installation, reducing time and labor costs while enhancing safety in complex geological conditions.
The stainless steel self-drilling anchor bolt is engineered for diverse, demanding environments where durability is critical. Typical applications include:
This geotechnical reinforcement system addresses key engineering challenges by combining efficiency with resilience. For instance, in coastal tunnel projects, the self drilling anchor system allows for rapid installation in water-logged soils, while its stainless steel composition withstands saltwater assault, reducing lifecycle costs by up to 30% compared to traditional alternatives. Engineers report that the product's compatibility with standard accessories, such as SW46 series nuts and D42 series couplers, streamlines logistics and installation, further boosting adaptability across global sites.
As global infrastructure expands into corrosive environments, driven by urbanization and climate adaptation, the demand for robust anchoring solutions is escalating. The stainless steel self-drilling hollow anchor meets this need by enhancing safety in tunneling, mining, and civil engineering projects. By preventing corrosion-induced failures, it contributes to geotechnical safety, reducing risks of collapses or delays in critical operations. In Europe and America, where stringent regulations govern construction materials, this anchor's alignment with EN standards for stainless steel structural materials positions it as a preferred choice for sustainable development.
Market analysts highlight that innovations like this self drilling anchor bolt are pivotal for advancing infrastructure resilience. For example, in offshore wind farms, where anchors must endure harsh marine conditions, this product offers a reliable alternative to coated steel options, potentially lowering operational costs and extending service life. The drill-and-grout bolt technology also supports mining operations in humid regions, where ground stability is paramount for worker safety and productivity.
SupAnchor's launch of this product underscores its role as a leader in the soil nail system manufacturer sector, backed by extensive research and development. The company holds ISO certifications, including ISO 10208 and ISO 1720 for thread standards, ensuring quality and interoperability across its product range. With a presence in global projects from European tunnel networks to American mining sites, SupAnchor demonstrates a collaborative approach, working closely with engineers to tailor solutions for specific site conditions.
The brand message of being professional, innovative, and collaborative is evident in this development. By leveraging its position as the No.1 exporter in Asia, SupAnchor continues to drive advancements in ground anchor bolt factory technologies, setting benchmarks for durability and efficiency. Future plans include expanding the stainless steel variant to other diameters, such as 25mm, 38mm, and 51mm, to cater to a wider range of project needs, reinforcing its commitment to meeting diverse engineering challenges.
