The range includes fixed-angle components manufactured to a specified static installation angle and adjustable seating systems designed to suit project-specific requirements. 

Material

  • A2 Stainless Steel (304)
  • A4 Stainless Steel (316)

Specific Features

  • Accommodates tendon-to-bearing-surface misalignment
  • Fixed-angle and adjustable configurations available
  • Designed to suit project-specific geometry
  • Supports correct seating of the anchorage assembly
  • Compatible with geotechnical bar tendon systems
  • Bespoke sizes and bearing arrangements available

Performance

  • Accommodates angular variation at the tendon termination
  • Maintains full and stable contact between mating seating surfaces when correctly specified and installed
  • Offers fixed-angle or adjustable alignment correction
  • Can be integrated with rock netting and geotechnical anchorage assemblies 

Typical Applications

  • Soil nails and rock bolts
  • Ground anchor and tendon systems
  • Slope stabilisation works
  • Rockfall protection and rock netting
  • Retaining structures
  • Tunnel and portal works
  • Bridge and infrastructure strengthening
  • Coastal and marine geotechnical works 

Installation Notes

  • Confirm the required angle and assembly orientation before manufacture and installation
  • Ensure all mating seating surfaces are clean and fully engaged before tightening
  • Do not substitute individual components from a designed seating assembly without technical review

Dimensions & Design

  • Static Angle: Tapered components manufactured to a predetermined installation angle.
  • Adjustable: Hemispherical seating arrangements accommodate angular variation during installation.
  • Bespoke Design: Geometry developed to suit tendon size, bearing plate and project requirements. 

Product Range

Hemispherical Seating & Washer

An adjustable seating arrangement in which the hemispherical components accommodate angular misalignment between the tendon and bearing surface.

Dished Plate with Hemi Washer

A dished bearing plate combined with a hemispherical washer to accommodate angular variation at the tendon termination.

Taper Washer

Manufactured to provide a predetermined static installation angle where the required misalignment is defined at design stage.

Wedge Boss

A fixed or project-specific angled boss used where a larger angular correction or a substantial bearing interface is required.

Spike Plate

A formed plate used to secure and retain rock netting, available with an angular seating arrangement where required.
