Wedge   
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.

Anchor head
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

Anchor Bearing Plate
Anchor bearing plate is the key component, which transfer the load from anchor head to concrete under anchor. The method of transfer and distribution of stress affect the anti-cracking and load capacity of concrete. Bursting reinforcement used for distributing the concrete. For prevent concrete from crazing, and use the bursting reinforcement for strengthening tendons.

Metal Bellows
Metal bellows used for post tensionning prestress concrete structure or constructive pore-forming. It can be divided into round and flat by the section shape; divided into standard enhanced by radial stiffness; divided into metal and plastic tubes by materials, and the metal duct can be divided into galvanized and non-galvanized.
