Low Relaxation Non alloy PC Steel strand As per ASTM A416-06 Grade 270K
Product Description
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 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.
