What is PVC coated wire rope?

PVC Coated Wire Rope is a steel wire rope with a protective layer of polyvinyl chloride (PVC) on its surface. It has the strength of steel wire rope and the corrosion resistance, wear resistance and insulation of PVC. It is widely used in many fields and has a variety of diameters, structures, colors and materials. Wanzhi Steel has a large number of regular sizes in stock, welcome to learn more.

The core of PVC-coated wire rope

There are fiber core and wire rope core, specifically: Fiber Core (F.C.), usually polypropylene (P.C.), sometimes hemp (H.C.), and sisal. Independent Wire Rope Core (IWRC), Wire Strand Core (WSC), IWRC, and WSC are sometimes referred to as steel wire core or steel center.

PVC coated wire rope features

Are you looking for a strong, durable, abrasion and corrosion resistant steel wire rope? Then our plastic coated steel cable is exactly what you need!

• Strong corrosion resistance: PVC coating can effectively isolate steel from the external environment and improve its corrosion resistance. In harsh environments such as humidity, acid and alkali, the life of PVC coated steel wire rope is 3.5 to 5 times that of ordinary galvanized steel wire rope.
• Excellent wear resistance: In dynamic load operations such as lifting and transportation, its service life is 1.5 to 2 times that of ordinary steel wire rope, especially suitable for working conditions with frequent friction.
• Stable mechanical properties: The plastic coating process maintains the original high strength characteristics of the steel wire rope, and at the same time enhances the stability of the overall structure through the coating to meet the heavy load requirements.
• Beautiful and practical: It provides a variety of color options such as transparent white, black, yellow, green, and red to meet the aesthetics of different scenes, and the smooth coating is also easy to clean and maintain.

• Shock absorption and anti-extrusion: The plastic coating has elastic buffering characteristics, which can effectively absorb impact and reduce the risk of breakage under dynamic load.
  Fatigue resistance: The coating reduces internal stress concentration, and its durability is about 2 times that of ordinary hemp core or metal core steel wire rope, which is suitable for long-term cyclic use.
• Combining economy and safety: plastic coated wire rope has moderate cost, strong comprehensive performance, wide application scenarios, and high overall cost performance.

The composition of wire rope

• 1×7 structure: single strand 7 wires, 1 center wire + 6 outer wires spirally wrapped, simple structure, high rigidity and tensile strength, poor bending.
• 1×19 structure: single strand 19 wires, 1 center wire + 6 middle wires + 12 outer wires. More flexible than 1×7, but still maintains high strength and better fatigue resistance than 1×7.
• 7×7 structure: 7 strands × 7 wires, 7 strands of steel wire bundles, each bundle consists of 7 steel wires, good flexibility and torsion resistance, medium load capacity.
• 7×19 structure: 7 strands × 19 wires, 7 strands of steel wire bundles, each bundle consists of 19 steel wires, extremely high flexibility, excellent fatigue resistance, suitable for frequent bending.
• 7×7+FC structure: 7×7 steel wire rope + fiber core, such as sisal or synthetic fiber. The fiber core provides additional flexibility, good shock absorption performance, and light weight.
• 7×19+IWRC structure: 7×19 steel wire rope + independent steel wire rope core. It combines extremely high strength and flexibility, has good anti-extrusion performance, and is suitable for heavy-load and high-frequency use.
• 19×7 structure: non-rotating type, with multiple layers of steel wire reversely wound to reduce rotation, and almost no rotation when loaded, suitable for vertical lifting.

Commonly used plastic coatings

• PVC Coating: PVC is a low cost, general purpose coating and regularly used to cover 1X19, 7X7, and 7X19 stainless steel wire rope. PVC is a very flexible coating.
• Polypropylene Coating: This material is often chosen for its resistance to corrosion and chemical leaching, it has a resilience against most forms of physical damage, including impact and freezing.
• Nylon Coating: Nylon 11 and Nylon 12 a flexible, hard-wearing, and abrasion-resistant coatings. A superior Ideal for running applications requiring a covered wire rope.

Plastic coated steel rope representation method

Standard structure representation method

“Wire rope structure” + “PVC coating” + “Technical parameters”, the wire rope structure is expressed in number of “strands x number” of wires.
Example:

• 6×19+IWS + PVC Coating + Ø12mm (Core: Fiber) – Breaking Load: 18kN. The explanation is as follows: 6×19+IWS: 6 strands, 19 wires per strand, IWS means independent wire rope core.
• 6 x 25: indicates that the wire rope consists of 6 strands, which in turn have 25 individual wires.

Common share counts

1×3, 1×7, 1×19, 1×37, 3×3, 3×7, 6×7, 6×19, 6×12+7fc, 6×24+7fc, 6×15+7fc, 6×37, 19×7, 6x19S, 6x19W, 6x25Fi, 6x26WS, 6×36, 6x31WS, 8x19S, 8x19W, 8x25Fi, 8×26, SW35W*K7, 35W*7, 6*K36WS, 4V*39S+5FC.

Production Process

• Wire rope pretreatment: Remove oil, dust, and impurities on the surface of the wire rope, and perform surface treatment (phosphating, galvanizing) to enhance the adhesion and corrosion resistance of the coating.
• PVC coating material preparation: Select the appropriate PVC resin type, such as soft or hard PVC. Add plasticizers, stabilizers, pigments and other additives to improve performance.
• Coating process: Extrusion coating, the pretreated wire rope is passed through the extruder, and the PVC melt is extruded at high temperature and evenly wrapped on the surface of the wire rope.
• Cooling and curing: The PVC coating is quickly cured through a cooling trough or cooling device to form a stable structure.
• Tractive and reeling: Reel into a roll through a traction device, and the roll weight and roll diameter must meet customer requirements for easy storage and transportation.

• Quality inspection: Check the appearance, thickness, adhesion, and other properties of the coating to ensure that the product meets the standards.
• Packaging and storage: Labeling packaging for easy identification and reasonable storage.

How to choose the right PVC-coated steel cable?

• Determine load requirements: Check the working load limit (WLL) and breaking strength depending on the application.
• Environment of use: To prevent saltwater exposure, ensure a high-grade PVC coating. To protect against UV rays, choose UV-stabilized PVC.
• Flexibility needs: Static applications such as fencing and guardrails, recommend 1×7 or 1×19 cables, and dynamic applications such as lifting and rigging recommend 7×7 or 7×19 structures.
• Diameter and coating: The thicker the coating, the better the protection, but flexibility may be reduced.
• Color and aesthetics: Choose a color that matches the functional or decorative needs.
