Low Relaxation Prestressing Concrete Strand

High tensile strand for pre-stresses in concrete structure by virtue of improved proportional limit, higher ductility combined with higher strengths. They may be supplied in drawn or drawn straightened or stress relieved conditions. They can also be supplied in plain or indented finish. These are manufactured to different international standards and to the specific requirement of each customer.
