Detailed Manufacturing Process Flow of Chain Link Wire Mesh Fence

The production of a high-quality chain link wire mesh fence is a meticulously controlled process designed to ensure durability, strength, and longevity. The process typically begins with the selection of high-grade raw materials and proceeds through several stages of transformation and finishing.

Materials Selection:

• Steel Wire Core: Primarily low carbon steel wire (ASTM A824, A641) for standard applications or high tensile steel wire for enhanced security. Wire diameters typically range from 1.6mm (16 gauge) to 5.0mm (6 gauge), selected based on required strength and application.
• Protective Coatings:
  • Galvanization: Zinc coating applied through hot-dip galvanizing (ASTM A116, A392) or electro-galvanizing, offering robust corrosion resistance. Hot-dip galvanization typically yields a thicker, more durable coating, extending service life significantly.
  • PVC/Polyester Coating: A layer of polyvinyl chloride (PVC) or polyester applied over galvanized wire, providing superior corrosion resistance, aesthetic appeal (available in various colors), and a smoother finish. This process often involves extrusion bonding or fusion bonding.

Manufacturing Process Steps:

1. Wire Drawing: Raw steel rods are drawn through a series of dies to achieve the desired wire gauge (diameter). This process increases the tensile strength and consistency of the wire.
2. Weaving/Knitting: The drawn wire is fed into automated chain link weaving machines. These machines continuously form a series of interlocked wire spirals that are woven together to create the characteristic diamond mesh pattern. The mesh size (diamond opening) is precisely controlled during this stage.
3. Knuckling/Barbing: At the top and bottom edges of the fabric, the wire ends are either "knuckled" (bent over to form a closed loop for safety and a neat finish) or "barbed" (twisted into sharp points for enhanced security). The choice depends on the application's security requirements.
4. Coating (if not pre-coated): If non-pre-galvanized wire is used, the woven fabric undergoes a hot-dip galvanization process where it is immersed in a bath of molten zinc. For PVC-coated fence, the galvanized wire or finished fabric is coated with PVC through an extrusion or fusion process.
5. Quality Control & Testing: Throughout the process, rigorous quality checks are performed.
   • Material Composition: Spectroscopic analysis of steel and coating materials.
   • Wire Diameter: Caliper measurements for consistency (e.g., +/- 0.05 mm tolerance).
   • Mesh Size: Dimensional checks of diamond openings.
   • Coating Thickness: Magnetic induction gauges for zinc (e.g., minimum 2.0 oz/sq ft or 610 g/m² for Class 2 hot-dip galvanized as per ASTM A392) and PVC (e.g., 0.25mm to 0.40mm).
   • Adhesion Tests: For PVC coatings, to ensure proper bonding to the wire.
   • Tensile Strength: Material testing according to ASTM A824 standards to ensure structural integrity.
   Compliance with international standards such as ISO 9001 (Quality Management Systems), ASTM A392 (Standard Specification for Zinc-Coated Steel Chain-Link Fence Fabric), and ANSI/UL 752 (Bullet Resisting Equipment - for high-security variants) is paramount.
6. Packaging: Finished rolls of chain link wire mesh fence are compacted, secured, and often wrapped for protection during transit, ensuring product integrity upon delivery.

A properly manufactured and coated chain link wire mesh fence can achieve a service life of 15-20 years for standard galvanized options and upwards of 25-30 years for heavily galvanized or PVC-coated systems, even in challenging environments like petrochemical, metallurgy, and water supply & drainage facilities.
