Prestressing Strand Unbonded China
Prestressing Strand (also referred to as Prestressed Concrete Steel Strand), is made from the stranding of seven wires of high carbon steel wire rod, and mainly used as auxiliary reinforcing strand for concrete structures. It has the following characteristics and advantages:
● High tensile strength and low relaxation
● Higher fatigue, higher breaking loads and corrosion resistance
● Better performance at elevated temperature
● Stable modulus of elasticity
● High bonding force
● Reduce distortion and construction weight
