Steel Wire Strands

PC STRAND
the prestressed concrete steel strand, is a twisted steel cable composed of 2, 3, 7 or 19 high strength steel wires and is stress-relieved (stabilized) for prestressed concrete or similar purposes. PC Strand is mainly used for concrete structure, such as railway and highway, overhead crane construction, multi-floor industrial building and etc. Products have been widely applied to the engineering construction of large scale of railroads, highways, bridges.
Classification
According to the number of steel wire in a strand: 2 wire strand, 3 wire strand, 7 wire steel strand and 19 wire steel strand.
According to the surface morphology can be divided into smooth steel strand, scoring strand, mold pulling strand (compact), coated epoxy resin steel strand.
Stranded wire types according to the surface shapes: smooth plain steel strand, indented steel strand, Helix strand, compact steel strand (compact), Epoxy coated PC Strand (7 wires individually coated), etc.
It can also be categorized by wire diameter, or intensity level, or by standard.
Common sizes: Diameter 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm indented PC wire for metal building materials.

Wire Shapes: Plain wire, Spiral ribbed steel wire
