Core Grip, Ultimate Security—Providing foolproof prestressed locking solutions for bridges and structural engineering.
Welcome to our PT Anchor Wedges & Grips category. As the most critical load-bearing components in post-tensioning anchorage systems, wedges are directly responsible for locking and transferring the high tensile forces of steel strands. We specialize in producing high-quality, high-wear-resistance, and high-fatigue-life wedges and anchor accessories. Widely used in high-speed railways, long-span bridges, nuclear power plants, and large industrial buildings, our products ensure the long-term, absolute safety of prestressed structures under rigorous loads.
· 2-Piece / 3-Piece Standard Wedges: Designed for conventional steel strands, featuring specially treated tooth surfaces that achieve a perfect fit and stable self-locking with anchor rings.
· High-Fatigue / Heavy-Duty Special Wedges: Engineered specifically for extreme dynamic cyclic loads or ultra-high-tonnage prestressing systems, effectively extending structural service life.
· Reused / Tool-Type Wedges: Tailored for construction site tensioning operations, featuring high wear resistance and easy release for safe, multiple reuses with jacks and tools.
· Auxiliary Anchorage Components & Retaining Rings: Essential accessories that ensure precise positioning and uniform force distribution of the wedges during installation and tensioning.
· Precision Forging & Heat Treatment: Manufactured from premium alloy steel using advanced carburizing and quenching technologies, achieving an optimal balance of surface hardness and internal toughness for superior wear and pressure resistance.
· Exceptional Gripping Force & Safety: Unique tooth profile designs ensure uniform bite on steel strands, delivering unmatched slip-resistant anchorage performance without damaging the strand.
· Rigorous Fatigue & Static Load Testing: Every batch undergoes strict static load anchorage efficiency and cyclic load fatigue tests in compliance with international standards (such as ASTM, BS, and ISO).
· Comprehensive Compatibility: Perfectly matches standard and specialized prestressed steel strand diameters (such as 12.7mm and 15.24mm), seamlessly integrating with various mainstream anchorage systems.
