Steel Strand
Steel strand, commonly referred to as steel strand wire, is a critical material in modern engineering and construction. Composed of multiple steel wires twisted together, it is known for its exceptional strength, durability, and versatility. Wanzhi Steel produces steel strands of various structures. The factory stocks stainless steel, carbon steel, and other materials, and the length and diameter can be customized.

Performance And Advantages
Steel strand is widely recognized for its superior performance in demanding applications. It is a preferred choice in construction, transportation, and industrial sectors:
- High Tensile Strength: The steel strand is designed to withstand tremendous tensile forces. For example, 270 ksi steel strand (270,000 psi) is often used in high-stress applications such as bridges and high-rise buildings.
- Durability: Steel strand resists abrasion, fatigue, and environmental degradation, especially when coated or made of corrosion-resistant materials such as stainless steel.
- Flexibility: Despite its high strength, steel strands can be bent and formed, making it suitable for complex structural designs.
- Load-Bearing Capacity: The steel strand is capable of supporting heavy loads, which is why it is often used in steel strand cables for suspension bridges and steel strand ropes for lifting and rigging.
These properties make steel strands indispensable in applications where strength, reliability, and longevity are critical.

Types of Steel Strand
- Steel Strand for Prestressed Concrete (PC Steel Strand): This type is specifically designed for use in prestressed concrete structures. It is tensioned before the concrete is poured, providing additional strength and reducing the risk of cracking. PC steel strand also called prestressed steel strand, is widely used in bridges, parking structures, and high-rise buildings.
- Steel Strand Cable: It is typically used in large construction projects and is critical for suspension bridges, cable-stayed bridges, and other structures that require high tensile strength and flexibility.
- Electro Steel Strand: This type is used for electrical applications due to its conductive properties. It is commonly used in transmission lines and other electrical infrastructure.
- Argon Steel Strand: Known for its high purity and oxidation resistance and is used in specialized industrial applications such as aerospace and precision engineering.

Galvanized Steel Cable Packaging
- Galvanized Steel Strand: It is coated with a layer of zinc for enhanced corrosion resistance, making it ideal for outdoor and marine environments. It is also not an inexpensive alternative to stainless steel strands.
- Stainless Steel Strand: As the name implies, the material is stainless steel. Stainless steel strand has superior corrosion resistance to all materials and is highly resistant to corrosive environments. It can be exposed to chemical and marine environments.
- Steel Rope Strand: It consists of multiple strands of steel strands twisted together for excellent performance in lifting, rigging, and towing applications. Wire rope is a variant of cable that consists of metal wires and strands twisted into a spiral. Typically wire rope refers to cable that is at least 3/8 inch thick.
Uses
- Construction: Steel strand for prestressed concrete is widely used in bridges, buildings, and other infrastructure projects.
- Transportation: Steel strand cables are essential in the construction of suspension and cable-stayed bridges.
- Industrial applications: Electro steel strand and argon steel strands are used in specialized machinery and equipment.
- Marine and outdoor: Galvanized steel strands and stainless steel strands are preferred for this scenario.
- Lifting and rigging: Steel rope strand is used for cranes, elevators, and other lifting equipment.

Stainless steel and other specialty grades are available for special applications. Most strands are made from round wires. Triangular and shaped wires are used for special structures.
Typically, the higher the strength of the strand, the lower its ductility.
What are the production steps of steel strands?
Wire preparation
High quality wire rod (high carbon steel or low alloy steel) → pickling and rust removal → Multiple cold drawing by wire drawing machine → annealing → galvanizing/epoxy coating (optional)
Twisting steps
arranging a number of steel wires (usually 2-7) → twisting by stranding machine → pre-tensioning treatment → low temperature tempering (eliminating internal stress) → cooling → surface treatment (oiling/waxing/polymer coating) → cutting and winding → specification, model production batch marking

Packing method
Wrap with moisture-proof paper, plastic film, or woven bag and secure with steel straps.
- Coil packing: rolled into coils and bundled with strapping tape.
- Spool Packaging: Larger quantities are wrapped around spools and placed in protective sleeves.
- Box Packaging: Smaller lengths are packed in boxes, usually with protective pads.

Influencing factors
- High carbon steel, low alloy steel as the main raw material, if the use of stainless steel will increase the cost.
- Diameter, strength grade (e.g. 1570MPa, 1860MPa), structure (e.g. 1×7, 1×19) will affect the price.
- galvanized, coated with epoxy resin treatment process, can enhance the performance, but will increase the price.
Recommended application types and prices
