PC steel wires are low relaxation and high tensile strength, which are widely used in reinforcement for concrete industry, such as large-span bridges on railway and highway, overhead crane beam, rock-soil anchoring project, multi-storey industrial buildings, stadiums, coal mines and etc.
Types of prestressed PC steel wire
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.
3. In accordance with the surface coating, high tensile PC steel wire 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: plain surface
prestressed steel wire, spiral ribbed (or helix grooved) prestressed steel
wire, nicks (indented) prestressed steel wire and so on.
