Manufacturing Process: From Wire to Robust Fence
The creation of a high-quality Metal Chain Link Fence is a sophisticated process that ensures durability and performance. Here's a detailed breakdown of our manufacturing process:
Manufacturing Process of Chain Link Fence Metal
Wire Drawing and Annealing
High-carbon steel rods are first drawn through a series of dies to reduce their diameter to the desired wire gauge (e.g., 9 gauge, 11 gauge). This process increases the wire's tensile strength. Following drawing, the wire undergoes annealing, a heat treatment process that softens it to improve ductility and workability, making it suitable for weaving.
Galvanization / Coating
The drawn wire is then galvanized to protect it from corrosion. This can be done in two primary ways:
- Hot-Dip Galvanization (GAW - Galvanized After Weaving): The most common and effective method. The finished woven fabric is submerged in a bath of molten zinc, ensuring every part, including cut ends and joints, is thoroughly coated. This offers superior corrosion resistance conforming to standards like ASTM A392.
- Electro-Galvanization (GBW - Galvanized Before Weaving): Wire is electrolytically coated with zinc before weaving. This provides a uniform, smooth finish but a thinner coating compared to hot-dip.
- PVC Coating: For colored fences or enhanced corrosion resistance, galvanized wire may be coated with PVC (Polyvinyl Chloride) through an extrusion process. This meets standards like ASTM F668.
Weaving the Fabric
The galvanized or PVC-coated wire is fed into specialized automatic weaving machines. These machines weave the wire into the characteristic diamond pattern. Two wires are twisted around each other and then interlocked with adjacent pairs, forming the mesh. The mesh size (e.g., 2 inch) and height are precisely controlled during this stage. The selvage (edge finish – Knuckled or Twisted) is also formed by the machine.
Quality Inspection & Testing
Once the fabric is woven, it undergoes rigorous quality control inspections. This includes checking for:
- Mesh Consistency: Ensuring uniform diamond size.
- Wire Gauge Accuracy: Verifying wire diameter.
- Coating Adhesion & Thickness: Testing the zinc or PVC coating for uniform application and adherence to standards (e.g., ISO 9001, ASTM A392 for galvanized, ASTM F668 for PVC coated).
- Tensile Strength: Samples are tested to ensure they meet specified strength requirements.
- Overall Dimensions: Height and length of the rolls are checked.
Packaging and Dispatch
The finished **metal chain link fence** rolls are then compacted, wrapped, and prepared for shipping. Posts, fittings, and accessories are also prepared for a complete fencing solution. Each roll is securely packaged to prevent damage during transit to our global clientele.
