PC strand, or prestressed concrete strand, is a type of high-strength steel wire that is used in the construction of prestressed concrete structures. It is typically made of high-carbon steel and is coated with a protective layer to prevent corrosion.

PC strand is used to provide tensile reinforcement in prestressed concrete beams, slabs, and other structural elements. It is typically used in combination with other reinforcing materials, such as rebar, to provide the necessary strength and stiffness to the structure.

PC strand is produced by cold-drawing high-carbon steel wire through a series of progressively smaller dies, which increases its tensile strength and gives it a smooth, round cross-section. It is then coated with a protective layer, such as galvanized zinc or epoxy, to prevent corrosion and improve its durability.

PC strand is a key component in the construction of prestressed concrete structures, which are used in a wide range of applications, including bridges, buildings, and other types of infrastructure. It is known for its high strength, corrosion resistance, and ability to withstand extreme loads and stresses.
