PC strand with 7 strands that are used in the areas such as bridge girder production, prefabricated construction elements, ground and mine anchorages, nuclear power stations, silo constructions, housing constructions are produced according to the ASTM, BS, EN, TSE and JIS standards.
Primary advantages provided by PC Strand:
- Having high tensile strength.
- Potential great prestressing in small edges.
- Less need for anchorage and application labor.
Advantages of the products with lower relaxation
- More tensile and yield strengths.
- Super durability against fatigue and corrosion.
- Consistent load elongation relation.
- Super straightening feature.
