PC Wire

The standard of PC steel wire:
1.GB/T 5223-2002
2.ASTM A648
3.BS 5896-1980
4.ASTM A421

PC steel wire is mainly used for a variety of concrete structure reinforcement, such as large bridges, crane beams, cement poles, prestressed concrete pressure pipe, multi-factory frameworks.

Category:
Can be pre-stressed wire diameter, the intensity level, the surface coating or cross-section morphological classification:
1. according to diameter and can be categorized as: 4mm, 4.8mm, 5.0mm, 5.1mm, 6.0mm, 6.35mm, 7.0mm, 7.8mm, 8.0mm, 9.0mm, 10.0mm, 11mm, 12mm and so on.
2. according to intensity level can be classified as: 1470MPa, 1570MPa, 1670MPa, 1770MPa and 1860MPa so.
3. in accordance with the surface coating can be classified as: no coating prestressed steel wire, prestressed epoxy coated steel wire and galvanized prestressed steel wire.
4. in accordance with the surface morphology can be classified as: light round prestressed steel wire, spiral rib (spiral ribbed or helix grooved) prestressed steel wire, the pressure wave (crimped) prestressed steel wire or nicks (indented) prestressed steel wire and so on.
5. in accordance with treatment process can be categorized as follows: cold-drawn prestressing steel wire (no slack performance requirements) and low relaxation prestressed steel wire.
