Standard EN Sample
Specification for Nineteen-Wire Steel Strand for Prestressed Concrete
Also Known As:
The BS 4757:1971 standard outlines the requirements for high tensile steel strand used in prestressed concrete applications. The standard covers both the chemical composition and physical and mechanical properties of the strand.
The standard distinguishes between two types of strands: "as spun" strand and "treated" strand. Each type of strand has specific requirements that must be met.
The chemical composition of the strand is specified, ensuring that it meets the necessary standards for steel used in prestressed concrete applications.
Furthermore, the standard outlines the physical and mechanical properties that the strand must possess. These properties likely include tensile strength, elongation, bending characteristics, and diameter tolerances, among others.
By providing detailed requirements for the composition and properties of the steel strand, the BS 4757:1971 standard aims to ensure that the strand used in prestressed concrete meets the necessary quality and performance standards.
