China PVC Coated Chain Link Fence Suppliers

PVC coated chain link fence consists of a steel wire core that is first galvanized for corrosion resistance and then extruded with a polyvinyl chloride (PVC) layer. The coating adds a barrier against moisture, chemicals, and UV exposure while providing a smooth, colored finish.

The resulting product combines the tensile strength of steel with the protective properties of PVC, making it suitable for environments where both durability and appearance matter.

Material and Construction

The core wire is typically low‑carbon steel with a diameter ranging from 2.0 mm to 4.0 mm, depending on the required mesh strength. Prior to PVC application the wire receives a zinc coating of 10‑20 g/m² to inhibit rust formation.

After galvanization the wire is woven into a diamond pattern mesh. Common mesh openings are 50 mm × 50 mm, 60 mm × 60 mm, or 75 mm × 75 mm, which determine the fence’s visibility and climb resistance.

The PVC extrusion adds a uniform coating thickness of 0.3 mm to 0.8 mm on each side of the wire. The compound includes UV stabilizers and impact modifiers to maintain flexibility and colour stability over years of outdoor exposure.

Coating Process

The extrusion line pulls the galvanized wire through a heated die where molten PVC is forced around the strand. Precise temperature control ensures proper adhesion between the zinc layer and the polymer.

Immediately after extrusion the coated wire passes through a cooling bath to set the thickness. Samples are taken inline for coating uniformity checks using a micrometer or non‑destructive gauge.

Adhesion is verified by a peel test according to ASTM D903, with typical values exceeding 1.5 N/mm, indicating that the coating will not delaminate under normal handling.

Technical Specifications

Applications

In sports facilities the fence provides a clear boundary while allowing spectators to see the field. The PVC colour can be matched to team branding, and the smooth surface reduces the risk of abrasion injuries.

Industrial sites use the fence to secure perimeters where chemical splashes or moisture are present. The PVC layer prevents direct contact between the steel core and corrosive agents, extending service life compared with bare galvanized mesh.

Agricultural installations benefit from the fence’s visibility for livestock containment and its resistance to rust in humid climates. The coating also limits the accumulation of dirt, simplifying cleaning routines.

Quality Control

Each production lot undergoes coating thickness measurement at multiple points along the wire using a calibrated magnetic induction probe. The acceptance criterion is a minimum of 0.30 mm PVC on each side.

Adhesion strength is tested by peeling a 25 mm length of coated wire at a 180° angle; results must exceed the specified threshold to prevent delamination during handling.

Corrosion resistance is validated through a salt‑spray test (ASTM B117) for 500 hours, after which the wire must show no red rust beyond the zinc layer.

Visual inspection checks for uniform colour, absence of bubbles, and proper selvage formation before the product is rolled.

Customization Options

• Fence height from 0.9 m to 3.0 m in 0.1 m increments
• Mesh size selection: 38 mm, 50 mm, 60 mm, 75 mm, 100 mm
• PVC colour choices: green, black, white, blue, custom RAL upon request
• Selvage types: twisted, barbed, or knuckle‑top for safety
• Optional top tension wire or bottom tension cable for added stability

Packaging and Shipping

Finished rolls are typically wound on a core with an inner diameter of 50 mm and an outer diameter not exceeding 300 mm. Roll width corresponds to the fence height, and the length is adjusted to meet project requirements, commonly 20 m or 25 m per roll.

Each roll is wrapped in a UV‑stable polyethylene film to protect the PVC surface from scratches during transit. Rolls are then placed on pallets, secured with strapping, and labelled with product code, dimensions, and batch number.

For export shipments, pallets are fitted with corner boards and stretch‑wrapped to resist moisture and shifting. Documentation includes material safety data sheets and inspection certificates upon request.

Frequently Asked Questions

Can dimensions be customized?

Yes, fence height, mesh size, roll length, and coating colour can be adjusted to match project specifications. Provide the required parameters when requesting a quotation.

What information is needed before quotation?

Project drawings or a simple list of required height, length, mesh size, colour, and any accessories such as posts or tension wires will enable an accurate price and lead time.

Which materials are available for the core wire?

The core is low‑carbon steel with a zinc coating; stainless steel or aluminium cores can be supplied upon special request for specific corrosion or weight considerations.

How is quality inspected?

Coating thickness, adhesion, and corrosion resistance are tested in accordance with ASTM standards. Visual checks are performed on every roll before packaging.

What packaging methods are available?

Standard packaging includes polyethylene film wrapping and palletizing. Additional protection such as corner boards, moisture barriers, or custom crates can be arranged.

How are export shipments protected?

Pallets are stretch‑wrapped, strapped, and fitted with corner boards to resist shifting and moisture. All shipments comply with international export packaging guidelines.

What is the typical production lead time?

Lead time varies with order size and customization but generally ranges from 2 to 4 weeks after receipt of confirmed specifications and deposit.

How are samples arranged?

Sample sections of 1 m length can be provided upon request, typically shipped via express courier with the customer covering freight costs.
