A steel strand is a steel product composed of multiple steel wires. The surface of carbon steel can be added with galvanized layer, zinc-aluminum alloy layer, aluminum cladding, copper-plated layer and epoxy resin coating according to needs. )wait.
According to classification, steel strands are divided into
1- Classification by use: prestressed steel strands, (for electric power) galvanized steel strands and stainless steel strands, among which the prestressed steel strands are coated with anti-corrosion grease or paraffin and then covered with HDPE, which is called unbonded prestressed steel Stranded wire (unbonded steel strand), prestressed steel strand is also made of galvanized or galvanized aluminum alloy steel wire.
2- Classified by material properties: steel strand, aluminum clad steel strand, stainless steel strand.
3- Classification by structure:
Prestressed steel strands can be divided into 7 wires, 2 wires, 3 wires and 19 wires according to the number of steel wires. The most commonly used structure is 7 wires.
Galvanized Steel Cable Assembly and Aluminum Ferrule Wire Rope for electric power are also divided into 2, 3, 7, 19, 37 and other structures according to the number of steel wires. The most commonly used structure is 7 wires.
4- Classification by surface coating:
It can be divided into (smooth) steel strands, Galvanized Steel Turnbuckle, epoxy resin coated steel strands, aluminum-clad steel strands, copper-plated steel strands, plastic-coated steel strands, etc.
Steel strand production process
The manufacturing process is divided into monofilament manufacturing and stranded wire manufacturing. The (cold) wire drawing technique is used to manufacture monofilaments. Depending on the material of the product, it can be high carbon steel wire rod, Stainless Steel Wire rod or medium and low carbon steel wire rod. Zinc, should be electroplated or hot dipped on the monofilament. Stranding machines are used to twist multiple steel wires into one product during the manufacturing process of strands. The prestressed steel strand also needs to be continuously stable after forming. (no scroll) Done.
The application fields of steel strand are
Wire Rope Ferrule is usually used for catenary cables, stay cables, core wires or reinforcements, etc., and can also be used as ground/earth wires for overhead power transmission, isolation cables on both sides of roads or structural cables in building structures. Commonly used prestressed steel strands include uncoated low-relaxation prestressed steel strands (uncoated steel strands for prestressed concrete) and galvanized (galvanized) steel strands, which are often used in bridges, Construction, water conservancy, energy and geotechnical engineering, etc., unbonded steel strands or single-strand steel strands are often used in floor slabs, foundation engineering, etc.
