Unbonded steel strand manufacturer: What are the classifications of steel strands?

Unbonded steel strand manufacturer: Steel strand is a steel material made by twisting multiple steel wires together. The carbon steel surface can be coated with zinc, zinc-aluminum alloy, aluminum, copper, or epoxy coatings. Depending on the needs, then steel strand manufacturer: What are the classifications of steel strands?

Unbonded steel strand manufacturer: What are the classifications of steel strands?

1. Classification by use

Prestressed steel strand, galvanized steel strand (for power), and stainless steel strand. Among them, prestressed steel strand coated with anticorrosion grease or paraffin is called unbonded steel strand. Prestressed steel strand is also made of galvanized or galvanized aluminum alloy steel wire.

2. Classification by material properties

Unbonded steel strand manufacturer: Steel strand, aluminum-clad steel strand, stainless steel strand.

3. Classification by structure

(1) Prestressed steel strands can be classified into 7-wire, 19-wire, and other structures according to the number of wires; 7-wire structure is commonly used.

(2) Galvanized steel strands and aluminum-clad steel strands for power are also classified into 2, 3, 7, 19, 37, etc., structures according to the number of wires; 7-wire structure is commonly used.

4. Classification by surface coating

(1) Can be divided into (smooth) steel strand, galvanized steel strand, epoxy coated steel strand, aluminum-plated steel strand, copper-plated steel strand, plastic-coated steel strand, etc.

(2) Unbonded steel strand manufacturer: Galvanized steel strand is usually used for tensioned cables, inclined cables, reinforcing cores, etc. It can also be used as ground wires for overhead power transmission, blocking cables on both sides of highways, or structural cables in building structures. Commonly used prestressed steel strands include uncoated low-relaxation prestressed steel strands and galvanized steel strands, often used in bridge, building, water conservancy, energy, and geotechnical engineering. Unbonded prestressed steel strands are often used in floor slabs and foundation engineering.

Unbonded steel strand manufacturer: What is steel strand?

1. Steel strand is composed of many steel wires twisted together, so we call it steel strand. This kind of steel strand is usually used in large construction sites or bridge construction.

2. Unbonded steel strand manufacturer: Adding a carbon steel layer to the steel strand can serve as a good carrier for power supply, but many coatings are also introduced. Steel strands are mainly divided into prestressed steel strands and galvanized steel strands, and different types of steel strands have different properties and characteristics. However, the commonly used steel strands are prestressed steel strands or galvanized steel strands, and others are not used for a long time.

3. The steel wires of this steel strand are coated with an anti-corrosion coating, which has a good anti-corrosion effect. During the manufacturing of this steel strand, there will be a division, such as single-strand wire and multi-strand wire, but most steel strands are made of multi-strand wire. If galvanizing is required, it can be heated or electroplated on the single wire. The products synthesized by prestressed steel strands are mostly tied to the I-beam wheel in the later stage, and then they can be sold to the construction site.

4. Unbonded steel strand manufacturer: The elongation of steel strand is strictly controlled, and most of them are wrapped by anchors or jacks, and the elongation length cannot be directly measured.
