Kinwey offers Prestressed Concrete Wires (pc wire) in mainly two types: Mono pc wire and Multi-wire strand.
PC steel wires are widely used in concrete construction industry for pre-stressed steel structures: large-span bridges ( stay cable system), overhead crane beam, cement poles, coal mines rock-soil anchoring project, multi-storey frameworks (slab and hollow floors), subway, railway sleepers, dams, shell safety of nuclear power stations, high-rise buildings (television tower, water towers, concrete silo, sewage treatment, hydropower project, stadiums) and etc.
Quality: ASTM A-416, BS 5896, JIS G3536, the standards and cutomized specifications.
Common wire materials for production: High tensile wires, plain or galvanized.
The process involves the continuous heating and stretching of a cold drawn high-carbon steel wire to produce a finished product with a much improved yield stress and greatly reduced load relaxation.
PC Wire / Strand Classifications
Prestressing concrete steel wire can be divided according to wire diameter, the intensity level, the surface coating or cross-section:
1. According to diameter, PC steel wire 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 tensile strength, pc wire can be classified as: 1470MPa, 1570MPa, 1670MPa, 1770MPa and 1860MPa.
3. According to the surface coating, pc wire can be classified as: uncoated prestressed steel wire, prestressed epoxy coated steel wire and galvanized prestressed steel wire.
4. According to forms of the surface, it can be classified as: Round plain wires, spiral ribbed (spiral ribbed or helix grooved) steel wires, crimped wires, slotted (indented) wires, and so on.
5. According to wire treatment process, pc wire can be categorized as follows: cold-drawn pc wire and low relaxation pc wire.
6. According to wires applied, pc wire can be classified as single individual pc wire and helically stranded wire ( pc strand).
7. According to applications, pc wire / strand can be divided into:
Un-bonded strand: zinc coated, grease filled; uv stabilized polymer sheath, for post tensioning
Bonded strand, retardant, galvanized bright, with PE shielding, for stable cable, suspension wire cable for bridge construction
8. According to structures, stranded wire can be classified into 2 wire strand, 3 wire strand or 7 wire strand mostly.
Prestressing steel wire / pc wire, functions differently compared with reinforcing steel (rebars):
Post-tensioning is very useful to defeat the natural weakness of concrete in tension and to optimize its strength in compression. In concrete structures, using high-tensile steel wire / strand placed in the element prior to casting will:
1,
Reduces occurrence of cracks .
2,
Increase in durability.
3,
Less deformations (improved serviceability).
4, Increase in shear capacity.
Since concrete is weak in tension, the reinforcing steel bar / rebar is used inside concrete for strengthening and reinforcing the tensile strength of concrete. Reinforcing steel bars are used to absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure.
