Our prestressed round anchorage system is engineered for high-performance post-tensioning and pre-tensioning applications in reinforced concrete structures. Designed to meet ISO 9001, ASTM A416, and EN 13391 standards, our round wedge anchorages ensure optimal load distribution, corrosion resistance, and long-term durability in bridge construction, high-rise buildings, and civil engineering projects.
✔ Ultra-High Load Capacity – Supports prestressing strands and tendons with minimal prestress loss for heavy-duty infrastructure.
✔ Corrosion-Resistant Design – Features epoxy coating or galvanized steel for marine environments and harsh conditions.
✔ Precision-Engineered Components – Ensures uniform stress distribution and seamless compatibility with multi-strand systems.
✔ Easy Installation – Works with post-tensioning ducts, couplers, and wedge systems for fast construction workflows.
✔ Durable High-Grade Steel – Manufactured from alloy steel (Grade 40Cr) for long-term structural integrity.
