SupAnchor Unveils Stainless Steel Self-Drilling Hollow Anchor for Corrosive Environments

As global infrastructure projects increasingly confront harsh environmental conditions—from salt-laden coastal areas to chemically aggressive industrial zones—engineers demand reliable geotechnical reinforcement systems that ensure long-term stability. SupAnchor, Asia's leading manufacturer and exporter of self-drilling anchors, has responded with a groundbreaking innovation: the Stainless Steel Self-Drilling Hollow Anchor. This product, designed to withstand high-corrosion challenges, integrates seamlessly into the company's proven self drilling anchor system, offering a durable solution for projects where traditional materials fail.

Technical Innovation and Core Features

At the heart of this new anchor is SupAnchor's signature "3-in-1 principle," which unites sacrificial drilling, grouting, and reinforcement into a single, efficient unit. This hollow bar anchor eliminates the need for separate casing systems, drastically reducing installation time and costs in unconsolidated or cohesive soils. Key technical highlights include:

• Corrosion Resistance: Fabricated from high-grade stainless steel, the anchor inherently resists rust, pitting, and degradation from moisture, saltwater, chemicals, and harsh weather, ensuring longevity in corrosive settings.
• Retained Mechanical Performance: Despite its focus on corrosion resistance, the anchor maintains robust mechanical properties. For example, the R32SS/15 model—a stainless steel variant in the R thread series—boasts an ultimate load of ≥405 kN and a yield load of ≥300 kN, comparable to or exceeding standard carbon steel anchors of similar diameter.
• Optimized Design: With thread specifications aligned with ISO standards (e.g., ISO 10208 for R thread) and a rib structure featuring a relative rib area of 0.21 to 0.33, the anchor maximizes bonding with grout while minimizing soil disturbance, keeping crack widths below 0.1 mm at maximum load.
• Accessory Compatibility: The anchor is designed to work with standard SupAnchor accessories, such as SW46 series nuts and D42 series couplers, simplifying installation and logistics for on-site teams.

To illustrate the technical specifications, here is a detailed table for the representative R32SS/15 model:

Application Scenarios: Addressing Diverse Engineering Challenges

This self drilling anchor bolt is engineered for a wide range of corrosive environments, making it a versatile choice for modern geotechnical projects. Key application scenarios include:

• Coastal and Marine Engineering: Ideal for reinforcing port terminals, stabilizing sea walls, and anchoring offshore wind farm infrastructure, where saltwater exposure necessitates superior corrosion resistance to prevent structural failure.
• Chemical and Industrial Projects: Suitable for anchoring in chemical plants, wastewater treatment facilities, and industrial zones with chemical vapor exposure, avoiding material degradation that compromises safety.
• Humid or Harsh Outdoor Environments: Effective for slope stabilization in tropical rainy areas, water conservancy project reinforcement, and permanent support in high-humidity underground spaces like subway tunnels with water seepage.
• Projects Requiring Long-Term Permanence: Perfect for historical building reinforcement, nuclear power plant auxiliary structures, and permanent retaining walls, ensuring structural integrity over decades without corrosion issues.

Industry Value: Enhancing Global Infrastructure Safety

The introduction of this geotechnical reinforcement system comes at a critical time as global infrastructure expands into challenging terrains. With rising investments in tunneling, mining, and urban development, reliable anchoring solutions are essential for geotechnical safety and sustainability. This drill-and-grout bolt not only reduces maintenance costs by eliminating rust-related replacements but also supports sustainable construction practices by extending the service life of projects in corrosive environments. For instance, in coastal regions prone to erosion or industrial areas with chemical runoff, this anchor helps mitigate risks, contributing to safer and more resilient infrastructure worldwide.
