Unbonded steel strands are mainly used to manufacture large, medium and small prestressed concrete components with various structural shapes in one, the last and the latter tensioning methods. Such as large railways, highway bridges, roof trusses, crane beams, industrial and civil prefabricated panels, wall panels, pipe piles, telephone poles and prestressed concrete water pipes, television towers, nuclear power plants and other construction projects.
