Detailed Product Description

Prestressed concrete strand is made from high carbon steel wire rod SWRH 82B, 77B. It can be used as a new steel material to take the place of traditional construction material, such as re-bar and wire rod. It is suitable for use in hoisting (with cranes, winches, pulleys, lifts, etc.) and construction of major bridges, silos, buildings, atomic reactor buildings, stadia, airport hangers, precast segments, etc.

Characteristics:

High rate of yield strength and ultimate strength; low relaxation; steady modulus of elasticity; stress relieved; high coherence with concrete.

Forms:

Plain, intended, and intended helical
