Prestressing Steel Introduction

Prestressing steel is usually produced in form of wire, strand and bar. Wire is made by cold drawing high carbon steel rod through a series of reducing dies. Strand is made from cold-drawn wires twisted together. Bar is produced by hot rolling low alloy steel which is then cold-worked by stretching to obtain the specified characteristic strength (Longbottom 1985; Threlfall 2002).
