Prestressed concrete steel wire and prestressed concrete strands are widely used in various building constructions because of their strong structure and stable performance. Many people may confuse them, but they are very different in appearance and performance. The following is to introduce the differences between the two from various aspects.

Prestressed concrete steel strand executive standard: GB/T5224-2014. Prestressed concrete steel wire executive standard: GB/T24238-2009.

The prestressed concrete steel wire is a single high-strength steel bar of different diameters. The prestressed concrete steel strand is composed of three to twelve strands, and the shape has thread grooves, but the number of grooves varies with the number of strands. The prestressed concrete steel strands used in prestressed concrete projects are usually 7 strands, each of which has different diameters and strengths. The specifications and names are expressed by the strength grade, the number of strands, and the single-strand diameter (or total diameter) of the prestressed concrete steel strand.

Prestressed concrete steel wires are widely used in concrete poles, prestressed concrete bridges, pressure pipes, railway sleepers, long-span roof trusses, and special structures in residential projects. Prestressed concrete steel strands are mainly used for roads, bridges, and prestressed reinforced concrete. In addition, they are also used for large international airports, construction of water conservancy dams, concrete protective walls of nuclear power plants, and high-rise buildings. 

Prestressed steel wire usually refers to a single steel wire with a diameter of 3-6mm, mostly dozens of wires in a bundle, while prestressed steel wire is formed by twisting two, three, five, and seven steel wires. There are generally several strands as a bundle, and generally no more than seven. The specific number of strands to be used should be determined according to actual needs.

Prestressed steel wire usually adopts metal or non-metal plating or coating such as galvanized, epoxy resin, etc., to improve the durability of the product and delay the service life. Secondly, in order to be better used in prestressed concrete, there are usually scratches on the surface. After the stranding process is completed, the prestressed steel strand usually undergoes a molding process. Through this process, the structure of the prestressed steel strand is more compact and the surface is more conducive to the grip of the anchor.
