Anchor Set

Product Specification

This Anchor Set is a precision-engineered fastening solution designed for critical, high-load applications. It combines an ultra-hard wedge for superior gripping force with a high-strength, corrosion-resistant barrel for structural support. Together, they form a reliable and durable system for secure load transfer in demanding environments.

Technical Specifications

1. Wedge (Anchor Clip)

• Material: 20CrMnTi Alloy Carburizing Steel

  • A premium case-hardening steel renowned for its excellent core toughness and superior surface wear resistance.

• Heat Treatment & Hardness:

  • Undergoes precise carburizing and quenching.

  • Surface Hardness: HRC 59-63, ensuring exceptional cutting/biting capability and abrasion resistance.

  • Effective Case Depth: 0.5 - 0.7mm. This creates a perfect gradient from a hardened surface to a tough core, preventing chipping or brittle fracture.

• Key Property: The extreme surface hardness guarantees a firm, lasting grip, while the ductile core absorbs shock and prevents sudden failure.

2. Barrel

• Material: Grade 45 Medium Carbon Steel

  • Provides an excellent balance of mechanical strength and moderate toughness.

• Heat Treatment & Hardness:

  • Treated with through-quenching and tempering.

  • Bulk Hardness: HRC 24-29, offering an optimal blend of strength for radial support and toughness for stress distribution.

• Surface Treatment Options:

  • Multi-Colored Zinc Plating: Provides durable cathodic (sacrificial) corrosion protection. The iridescent finish allows for visual inspection of coating integrity.

  • Black Electrophoretic Coating (E-Coat): Offers a uniform, high-adhesion, and aesthetically consistent black finish with excellent corrosion resistance. The electrophoretic process ensures complete coverage, even in complex geometries and recessed areas.

Key Advantages & Synergy

1. Optimized Hardness Combination:

   • Wedge (HRC 59-63): Engineered for maximum "bite" and wear life.

   • Barrel (HRC 24-29): Engineered for structural integrity and elastic support, distributing stress evenly to protect both the anchor and the base material.

2. Purpose-Built Material Science:

   • The 20CrMnTi wedge is designed for "hard surface, tough core" performance against high contact stress.

   • The Grade 45 steel barrel is engineered for reliable, bulk structural performance.

3. Enhanced Durability & Choice:

   • The wedge is protected by its deep case-hardened layer.

   • The barrel offers two premium finish options: the versatile Multi-Colored Zinc or the robust and uniform Black E-Coat, allowing selection based on corrosion needs and aesthetic preference.

4. Guaranteed System Performance:

   • The wedge and barrel are engineered as a matched pair, ensuring efficient load transfer and predictable behavior under tension.

   • Reduces the risk of premature failure due to component mismatch.

Typical Applications

• Anchorage systems for pre-stressed concrete structures.

• Geotechnical and slope stabilization (e.g., rock bolts, ground anchors).

• Foundation anchoring and tensioning mechanisms for heavy machinery.

• Terminal anchorages for bridge cables and cable-net structures.

• Any critical engineering application requiring reliable anchoring of high-strength tendons or rods into a base material.

Quality Commitment

Each component in the Anchor Set is manufactured to strict heat treatment and hardness specifications. Case depth for wedges and coating quality for barrels are key inspection points, ensuring consistent performance and forming the foundation for engineering safety and reliability.
