Galvanized steel strand

Folded surface mass
1, the surface of the steel wire in the strand should not be imprinted, scratched, broken, flattened and hard bending defects.

2, the surface of the steel strand must be free of oil, dirt, water and other impurities.

3. The galvanized layer on the surface of the split steel wire inside the strand wire should be uniform and continuous, without cracks and spalling. However, the surface of the zinc layer allows a small amount of flash and white thin layer and color difference.

The packing, marking and quality certificate of steel strand shall be carried out in accordance with the provisions of GB/T 2104.

In general, all kinds of steel strands should be delivered in trays. According to the agreement between the two parties, moisture-proof paper, linen, plastic woven cloth and other supplementary packaging can be added.

Galvanized steel strand is usually used for messenger wire, guy wire, core wire or strength member, etc. It can also be used as an earth wire/ground wire for overhead transmission, a barrier cable on both sides of a highway, or a structure cable in a building structure.

Prestressed Steel Strand

Steel strand corrosion resistance is better: bimetal no residue, better corrosion resistance. The horizontal continuous casting process uses high temperature melting, and the residue will overflow the copper surface after calcination, and will not remain in the rigid conductor covered with copper, so there will be no internal corrosion. When flat steel or building foundation is used as the grounding body, the reliability of steel strand grounding device is affected by poor corrosion resistance. Galvanized Angle steel (round steel) as a grounding body, slow steel corrosion. However, because zinc is more active than steel, zinc corrodes faster than steel. Due to the Angle between the galvanized layer and the soil, the corrosion is constantly changing, the stability is poor, the service life is short (generally less than 5 years), and a lot of work needs to be done.

Unbonded Steel Strand

Non-stick steel strand technology has been applied many times in social practical system engineering, especially in the vertical and vertical development directions of three-way prestressed box girder. Good performance. The application of longitudinal reinforcement bars in prestressed simple supported beams makes the small span first free from the tension bench, and then free from the process of hole formation and grouting, thus reducing the construction equipment.

Steel Strand for Concrete

The application of prestressed steel strand in concrete beams is very wide, including Bridges, high-rise buildings and water conservancy projects. Among them, bridge is one of the main fields of application of prestressed steel strand. As an important part of transportation, the quality and safety of Bridges are crucial to social development. The use of prestressed steel strand can greatly improve the bearing capacity and durability of the bridge, and ensure the safe operation of the bridge.

Various Steel Strands

According to the use of classification: prestressed steel strand, (electric) galvanized steel strand and stainless steel strand, which prestressed steel strand coated with anti-corrosion grease or paraffin after the package of HDPE is called unbonded prestressed steel strand, prestressed steel strand is also galvanized or galvanized aluminum alloy steel wire made.
