Multistrand Post-tensioning anchorage for 4 strands

The 4-Strand Multistrand Post-tensioning Anchorage is a heavy-duty prestressing component engineered for post-tensioned concrete projects (e.g., large-span bridges, high-rise buildings, and precast girders). Designed to secure 4 parallel steel strands simultaneously, this anchorage system delivers uniform load distribution and exceptional structural stability.

Key Features:

4-Strand Compatibility

Optimized for 4 standard bonded/unbonded steel strands (typically 15.2mm diameter), the anchorage’s multi-hole design ensures precise alignment and consistent tension transfer across all strands.

High Load Capacity

Constructed from high-strength alloy steel (compliant with EN 13391 standards), the anchorage withstands total tensile forces up to 1040kN (260kN per strand), suitable for heavy-load structural applications.

Seismic & Fatigue Resistance

The integrated wedge clips (heat-treated for hardness HRC 45-50) provide a slip-proof grip, while the robust anchor body resists cyclic loads and seismic stress—extending service life in harsh environments.

Efficient Installation

Pre-assembled wedge clips and a compact, bolt-mountable design reduce on-site assembly time, ideal for fast-paced construction schedules.

Applications:

Long-span bridges & viaducts

High-rise building columns & beams

Precast concrete segments (tunnels, stadiums)

Industrial plant foundations
