Description

The classic banana-shaped STS Wedge Block is the wedge seating component in the STS flat slab anchorage, which offers an economic and efficient solution to bonded post-tensioning in the construction industry. Conforming to the profile of the Flat Anchor, the Wedge Block is concave and self-aligning to allow the most effective loading of tensioning force to compress the concrete.

We stock and supply a wide variety of flat anchorage components to suit 12.7, 15.2 and 15.7 mm strand diameters, and can manufacture to meet your special needs by request. Our anchorage products are closely monitored by our dedicated quality team and quality certificates can be supplied on request for each and every delivery.

  • Self-aligning design
  • Large anchor contact area to help distribute loading
  • All STS Wedge Blocks meet Australian Standard AS1830 for grey cast iron
  • All 0.5” anchors comply with the Australian Standard AS1314 for prestressing anchorages
