Characteristics, applications and classification of prestressed concrete steel wire

 As a producer of prestressed concrete steel wire, I mainly talk about prestressed concrete wire from three perspectives: characteristics, applications and classifications, and I hope it will be helpful to you.


prestressed concrete steel wireFeatures of Prestressed Concrete Steel Wire

PC Wire (also referred to as Prestressed Concrete Steel Wire) is high tensile, low relaxation steel wire made from high-carbon steel and widely used for prestressed and post-tensioning technology in various shapes of PC structures. It has the following characteristics and advantages:

（1）High tensile strength and low relaxation

（2）More bonding stress between wire and concrete

（3） Stable modulus of elasticity

Uses of Prestressed Concrete Steel Wire

1. Reduces occurrence of cracks .

2. Increase in durability.

3. Less deformations (improved serviceability).

4. Increase in shear capacity.

Prestressed Concrete Steel Wire 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, Prestressed Concrete 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, Prestressed Concrete Steel Wire can be classified as: 1470MPa, 1570MPa, 1670MPa, 1770MPa and 1860MPa.

3. According to the surface coating, Prestressed Concrete Steel 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: 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: 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).

  Glass wool insulation  products and rock wool insulation products have now become the main insulation materials. Household needs, industrial needs, and major businesses also use various insulation materials. Can you tell the difference between glass wool and rock wool? Are their performance and their uses? In the current market, many people do not know which kind of venue uses glass wool and which kind of rock wool? Here   Huamei Glass Wool   and you break down the use and difference between the two in detail. Double-slotted XPS Order glasswool or rockwool now 1. The difference in production performance: Glass wool has a lower specific weight than rock wool, low content of slag balls, low thermal conductivity, long service life, and high fiber toughness. However, the maximum temperature of rock wool is about 600°C, and glass wool is only about 260°C.    Glass Wool      Glass wool uses glass as the main raw material, and it is a glass thin-flow fiber that is subjected to high-speed ce
