3pc grip wedges for prestressed concrete

Definition of Parts:

Anchor head is the key part of bearing the prestressing tension, The round anchor head is made by 45# high-quality carbon construction steel, and the flat anchorage is made by 40Cr steel. Anchor head include round anchor head and flat anchor head

Wedge is the key part of anchor system, which is made by high-class alloy steel 20CrMnTi. Its form is divided into two-chip and three-chip. The system apply to the two-chip YJM15 series, it can be used for round anchorage, flat anchorage, but also used for porous coupler
