How is a Chain Link Fence Made?

From Raw Steel Wire to Heavy-Duty Perimeter Protection

When securing property in Kenya—whether it’s a residential shamba in upcountry Kitale, a commercial godown along Mombasa Road, or a gated community perimeter—Chain Link Fencing remains one of the most reliable and trusted barriers.

Ever wondered how raw wire transforms into that durable, diamond-pattern mesh? At Durafence, we engineer and supply heavy-duty chain link fences built precisely to withstand local weather elements and security requirements.

Here is a look inside the manufacturing process of how a professional chain link fence is made.

Step 1: Wire Sourcing & Material Selection

The backbone of any strong chain link fence is the quality of the steel wire.

  • Low-Carbon Steel: The process begins with high-tensile, low-carbon steel rods drawn down to precise wire gauges (thicknesses). Low-carbon steel is chosen because it has the ideal balance of flexibility and strength—allowing it to absorb impacts without snapping.
  • Galvanization / Coating Choice: Depending on where the fence will be installed in Kenya, raw steel wire is either hot-dip galvanized (coated heavily with zinc to prevent rust in wet or humid coastal climates like Mombasa) or coated with a UV-resistant PVC layer (ideal for aesthetics and added protection against harsh tropical sunlight).

Step 2: Wire Drawing & Preparation

Before entering the weaving machine, the raw steel wire is pulled through a series of tungsten carbide dies in a process called wire drawing. This reduces the wire to the exact gauge required for structural integrity (such as heavy-gauge options used for industrial sites versus standard gauges for residential plots).

Step 3: Automatic Diamond Weaving (The Knitting Process)

This is where the signature diamond pattern is born.

  1. The Machine Feed: The prepared steel wire is fed continuously into advanced automatic chain link weaving machines.
  2. The Helix Formation: As the wire feeds through, a specialized rotating blade (or arbor) bends and flattens the wire into a spiral or helical shape—often called a “picket.”
  3. Interlocking: Each rotating spiral is screwed or interlocked seamlessly into the preceding vertical spiral. This continuous interlocking motion creates the iconic diamond mesh grid.
  4. Edge Finishing: As the sheet reaches the desired height (ranging from 4ft up to 10ft), the machine finishes the top and bottom edges either by knuckling (bending the ends back on themselves) or barbing (twisting the ends to form sharp points for extra security).

Step 4: Quality Testing & Tension Control

Quality control is vital to ensure the fence won’t warp or unravel under pressure. Durafence chain link rolls undergo rigorous testing for:

  • Tensile Strength: Ensuring the wire can withstand stretching during installation.
  • Coating Uniformity: Checking that the zinc or PVC coating has no gaps or thin spots prone to early rusting from rain or soil moisture.
  • Aperture Consistency: Making sure the diamond diamond-shape spacing remains uniform across the entire roll length.

Step 5: Compacting, Rolling & Packaging

Once woven, the continuous mesh sheet is mechanically compressed and rolled tightly into standard-length rolls. This makes it compact, easy to load onto transport trucks, and simple to unroll on-site across rough or uneven Kenyan terrain without tangling.

Why Manufacturing Standards Matter in Kenya

Not all chain link fences are created equal. Fences made from substandard, thin-gauge wire or poor galvanization rust out within a couple of rainy seasons.

Durafence supplies heavy-gauge, tightly woven, and corrosion-resistant chain link fences specifically designed to meet the rigorous demands of Kenyan infrastructural, agricultural, and residential projects.

Frequently Asked Questions

  • What type of steel is used for chain link fences? High-tensile, low-carbon steel wire is used because it provides the ideal balance of flexibility and structural strength to absorb impacts without snapping.
  • How does galvanization protect a chain link fence? Hot-dip galvanizing coats the steel wire in a protective layer of zinc, preventing moisture and oxygen from causing rust—making it ideal for wet or humid climates.
  • What are the edge finishes on a chain link fence? The top and bottom edges are typically finished either by knuckling (bending the wire back on itself for safety) or barbing (twisting the ends into sharp points for enhanced perimeter security).
  • How is a chain link fence made? A chain link fence is made by feeding high-tensile steel wire through automatic weaving machines that bend the wire into interlocking spiral helices. These spirals mesh together to form a continuous diamond pattern, which is then trimmed at the edges (knuckled or barbed), galvanized or PVC-coated for rust resistance, and rolled for installation.
