Characteris of Prestressed Concrete Strand

1.high tensile strength and elongation;low relaxation value;small stress losing;excellent durable anti-fatigue performance.

2.Grade: 250K / 270K / 290K, Tensile Strength: 1770Mpa / 1860Mpa / 1960Mpa, the 1000h Relaxation is 2.0% max and the elongation is 4.0% min.

3.Categories: plain,galvanized,PE coated,epoxy resin coated, spiral ribs, indented. 

 

4.Application of the pc strand

1. PC strand is used as cable for special bridges and maintenance of bridges.

2. PC strand is used in concrete pillars and supports for the construction of buildings, domes for nuclear power plants and reinforcement of LNG concrete tanks.

3. PC strand is used as floor and roof reinforcement for sports stadiums.

4. PC strand can be extensively used in construction materials for PC panels, high-pressure concrete water pipes, marine structures, towers and runways.
