XQV Wedge Blank – Prestressed Anchor Wedge Blank for Custom Machining

High-Quality Unfinished Wedge Blank for Post-Tensioning Systems – Customizable Hardness, Material & Surface Treatment

Product Introduction

XQV Wedge Blank is the initial form of the wedge in the prestressing anchorage system, referring to the semi-finished component without surface treatment, tooth pattern processing and precision calibration. Its core function is to provide a basic structural carrier for the subsequent finished grip, and it is transformed into a key component with anchoring capability through processes such as forging and machining. The XQV wedge blank follows strict technical standards in every link from material smelting to forging process, providing a reliable foundation for structural safety in key projects.

Key Features & Advantages

🏭 High-Quality Raw Material: Manufactured from 20CrMnTi alloy steel, ensuring excellent hardenability and wear resistance.

⚙️ Ready for Customization: No surface treatment, tooth pattern, or final calibration – ideal for in-house finishing to meet specific project requirements.

🔥 Strict Forging Process: Controlled from smelting to forging, guaranteeing consistent mechanical properties and defect-free blanks.

📊 Reliable Anchorage Performance: When finished, achieves ηa ≥95% anchorage efficiency and HRC58-62 hardness.

🔗 Wide Compatibility: Available for M15/M13 series and other strand specifications.

Application

XQV Wedge Blank is widely used as a semi-finished component in the production of prestressed anchor wedges. After final machining and heat treatment, the finished wedges are applied in the following fields:

Bridge Engineering: Used for post-tensioning anchoring of box girders, T-beams, and cable-stayed bridge tower zones. Wedges finished from these blanks provide reliable lock-off under dynamic traffic loads, meeting GB/T14370 and AASHTO standards.

Building & Infrastructure: Applied in high-rise building floor slabs, parking structures, stadiums, and industrial floors. The blank allows contractors to apply custom tooth patterns or surface coatings to comply with local codes.

Tunnel Lining & Support: For highway and railway tunnels, wedge blanks become permanent working grips in primary and secondary linings. The material (20CrMnTi) can be galvanized for corrosion resistance in underground water environments.

Dam & Hydropower Projects: Used in concrete gravity dams, arch dams, lock chambers, and hydraulic tunnel supports. Finished wedges achieve ηa≥95% anchorage efficiency, ensuring long-term stability under high water pressure.

Slope Stabilization & Ground Anchors: Wedge blanks are machined into tool grips or permanent anchors for landslide remediation, retaining walls, and deep excavation support. Custom hardness (HRC58-62) can be achieved through heat treatment.

Industrial & Nuclear Facilities: Employed in prestressed concrete containment vessels (nuclear power plants) and heavy machinery foundations. Blanks conform to international standards (ISO, CE, ASTM) for critical applications.
