Prestressed Anchorage Devices offer unmatched strength, flexibility, and reliability. They are a preferred choice for engineers and builders seeking durable, adaptable, and easy-to-install anchoring solutions across diverse construction, industrial, and marine applications.

Q: What are Prestressed Anchorage Devices, and how do they work?

A: These devices are mechanical components that anchor the ends of prestressing tendons (or steel strands) in concrete structures. They transfer the tension from the tendons into the concrete, allowing the structural element to carry higher loads and maintain integrity. 
In other words, when the tendon is tensioned, the anchorage device ensures that force is safely transmitted to the concrete, rather than slipping or damaging the concrete locally.

Q: What materials and finishes are typical for these anchorage devices?

A: They are typically made from high-grade materials such as carbon steel or stainless steel (and sometimes spheroidal graphite cast iron or other alloy steels) to ensure strength and durability. 
Finishes often include corrosion‑resistant treatments (e.g., hot‑dip galvanizing) to withstand harsh environments. 
These features help ensure long service life and reliable performance, even under high loads or in marine/harsh exposure.

Q: In which types of applications are these anchorage devices used?

A: They have a broad range of use in construction and civil/structural engineering, including:

• Prestressed concrete bridges and viaducts (for anchoring tendons in girders, cable‑stayed towers etc).

• Building structures (columns, beams, slabs) where prestressing is applied. 

• Hydraulic engineering works (dams, spillways) and foundation engineering (underground structures). 

• Also in industrial installations, marine/offshore platforms, and architectural mounts, where precise load transfer is required.

  
  

Q: How customizable are the anchorage devices (sizes, holes, patterns)?

A: Very customizable. According to the manufacturer:

• They offer different types to fit single‑strand, multi‑strand, or anchor plate configurations. 

• Dimensions, hole patterns (number of holes, diameter), and plate thickness/sizes can be adjusted to specific engineering requirements. For example, holes may range from 8mm to 30mm in diameter; plate sizes from ~50mm×50mm to ~200mm×200mm; and thicknesses 5mm to 20mm (in the related flat bearing plate example).

• Surface finish (smooth or textured) and edge chamfering can also vary.

  
  

Q: What factors should be considered to ensure proper performance and durability of these devices?

A: Important factors include:

• Corrosion protection: Choose appropriate material/finish especially for aggressive environments (marine, chemical exposure). The manufacturer emphasises “corrosion resistance” in its product features.

• Correct specification & sizing: The anchorage must match the tendon size, load capacity, and anchor pattern. Careful engineering is needed to ensure the anchorage zone in the concrete is properly designed. 

• Proper installation: Precision manufacturing and correct installation help ensure accurate fit and alignment, reducing the risk of local cracking or load‑transfer failure. The product emphasizes “precision manufacturing” and “ease of installation”. 

• Concrete zone design: The anchorage zone (where the force is transferred into the concrete) must be designed to handle bursting/spalling forces and ensure the anchorage device works as intended. 

• Maintenance and environment: Even with corrosion‑resistant materials, consider long‑term environmental effects and maintenance access.
