Classification

According to the number of steel wire in a strand: 2 wire strand, 3 wire strand, 7 wire steel strand and 19 wire steel strand.

According to the surface morphology can be divided into smooth steel strand, scoring strand, mold pulling strand (compact), coated epoxy resin steel strand.

They can also be classified by diameter, or intensity level, or standard.

Specification

In the description and list of the table we often see, there are 15-7Φ5, 12-7Φ5, 9-7Φ5 and other specifications of the prestressed steel strand.

To 15-7Φ5, for example, 5 said a single diameter 5.0mm of steel, 7Φ5 said seven of the steel wire to form a strand, and 15 that the diameter of each strand of 15mm, the total meaning is "one The beam consists of 7 strands of diameter 15 mm (each having a total diameter of about 15.24 mm, a dimensional deviation +0.40 -0.20; a diameter of about 5.0 mm per filament).

The general sectional area is calculated according to 140mm ^ 2. The theoretical breaking value is 140 * 1860 = 260.4kN, which can withstand the tension of 156.24-169.26kN according to the prestressing standard of 60% -65%.

Material

Using high-carbon steel wire rod, after surface treatment of cold drawn into steel wire, and then by the strand structure will be a number of steel wire stranded into shares, and then through the elimination of stress from the stabilization process.

In order to extend the durability, the wire can have metal or non-metallic coating or coating, such as galvanized, epoxy resin coating. In order to increase the bond strength of the concrete, the surface can have nicks and so on.

The prestressed strands of the mold are twisted to form a mold compression process, the structure is more compact, and the surface layer is more suitable for the anchor.

Production of unbonded prestressed steel strand (unbonded steel strand) using ordinary prestressed steel wire, coated with oil or paraffin after the package of high-density polyethylene (HDPE) into.

Feature

The main characteristic of the prestressed steel strand is high strength and relaxation performance is good, the other when the more straight. Common tensile strength level of 1860 MPa, as well as 1720,1770,1960,2000,2100 MPa and the like intensity level. The yield strength of this steel is also higher.

Features

Compacted steel wire rope, characterized by their high strength, flexibility, and durability. Becoming indispensable in various heavy-duty applications across industries like construction, mining, and maritime. These ropes through a special manufacturing process that compacts the steel wires, and then become a denser and more robust structure.

1.High breaking strength.
2.Very stabile rope construction with good fatigue properties.
3.Very high resistance against flattening and wear.
4.Wear-resistant, anti-seismic and stable in operation at high speed.
5.Good corrosion resistance and can work normally in the harsh environment of various harmful media.
6.Good softness, suitable for traction, pulling, binding and other purposes.

Compacted steel wire rope refers to the wire rope which has undergone a special process. The strands of standard rope are round strand rope but after undergoing the compacting process the wires and strands become flattened. It increases the contact area of all strands.
