Mono Anchor Head Wedge for unbond strand

The Mono Anchor Head Wedge is a high-performance prestressing component engineered for unbonded steel strands (commonly used in construction, bridges, and slope stabilization). Designed to deliver reliable, long-lasting anchorage, this system combines a robust anchor head and precision-machined wedge clips to secure single unbonded strands with exceptional tensile strength.

Key Features:

Optimized for Unbonded Strands

Tailored to fit standard unbonded steel strands (e.g., 15.2mm diameter), the wedge’s serrated inner surface creates a tight, slip-resistant grip—preventing strand displacement under heavy loads.

Durable Construction

The anchor head is cast from high-strength alloy steel (compliant with ISO 9001 standards), while the wedge clips are heat-treated for enhanced hardness (HRC 45-50), ensuring resistance to corrosion and fatigue in harsh construction environments.

Easy Installation

The single-hole design (paired with two matching wedge clips) enables quick, tool-free assembly: simply insert the unbonded strand, seat the wedges, and apply tension—reducing on-site labor time.

Marked for Traceability

Each anchor head is engraved with specifications (e.g., "0.50" for strand diameter compatibility) and brand identifiers (e.g., "HZ"), supporting quality control and project documentation.

Applications:

Ideal for prestressed concrete structures, including:

Residential/commercial building foundations

Highway bridges & overpasses

Retaining walls & slope reinforcement

Precast concrete components (beams, slabs)

Technical Specifications:

Compatible Strand: Unbonded 1x7 steel strand (15.2mm typical)

Tensile Capacity: Up to 260kN (meets ASTM A416 standards)

Material: Anchor Head (Alloy Steel); Wedges (Heat-Treated Carbon Steel)

Whether you’re a contractor, engineer, or project manager, the Mono Anchor Head Wedge for Unbonded Strand delivers the reliability and efficiency needed for high-stakes prestressing applications.
