The Art of Engineering: Manufacturing Process of Wire Mesh Baskets Retaining Walls (Gabion Fence)

The manufacturing of Gabion fence, which forms the robust backbone of wire mesh baskets retaining walls, is a precise multi-stage process that ensures product integrity, durability, and performance. Unlike traditional casting or forging, wire mesh production relies on advanced wire drawing, weaving/welding, and coating technologies. Our process adheres strictly to international quality management systems like ISO 9001, guaranteeing consistency and excellence.

Detailed Manufacturing Process Flow:

1. Wire Rod Selection & Quality Check:

   Input: High-quality low-carbon steel wire rods. These raw materials are selected based on their chemical composition and mechanical properties to ensure they meet the required tensile strength and elongation for gabion wire (e.g., conforming to ASTM A641 standards). A crucial initial check ensures no impurities or structural defects are present.

2. Wire Drawing:

   Process: The thicker steel wire rods are drawn through a series of dies to reduce their diameter to the desired gauge (e.g., 2.0mm to 4.0mm). This process not only reduces the wire's diameter but also enhances its tensile strength and refines its grain structure, making it tougher and more ductile.

3. Corrosion Protection (Galvanization/Galfan Coating):

   Process: The drawn wires undergo meticulous cleaning (degreasing, pickling) before being immersed in a bath of molten zinc (for Hot-Dip Galvanization) or a zinc-aluminum alloy (for Galfan coating). This creates a durable, sacrificial coating that protects the steel core from rust and corrosion. The coating weight is precisely controlled (e.g., min. 260 g/m² for HDG) as per relevant standards (e.g., ASTM A90/A90M).

4. PVC Coating (Optional, for Enhanced Protection):

   Process: For applications in highly corrosive environments (e.g., marine, industrial areas), galvanized wires are further coated with a durable layer of Polyvinyl Chloride (PVC). This is typically achieved by extruding PVC onto the galvanized wire. The PVC layer acts as a robust barrier against chemical degradation, UV radiation, and abrasion. The minimum PVC thickness is usually 0.5mm (0.02 in) and is rigorously checked.

5. Mesh Weaving or Welding:

   Process: Depending on the type of gabion (double-twist woven or welded mesh), the wires are either woven together on specialized machines to form hexagonal mesh or individually welded at each intersection to form square/rectangular mesh. Our Gabion fences primarily utilize advanced double-twist weaving machines, which produce a mesh that is incredibly strong and flexible, preventing unraveling even if a wire breaks.

6. Panel Cutting and Edge Reinforcement:

   Process: The large rolls of woven or welded mesh are then cut into specific panel sizes (front, back, sides, lid, base, diaphragms) according to standard gabion dimensions. Selvedge wires, which are typically thicker, are either integrated during weaving or mechanically attached to the panel edges to provide extra strength and prevent deformation when the basket is filled.

7. Folding and Assembly Preparation:

   Process: The cut panels are then folded flat for economical shipping. For ease of assembly on-site, pre-formed folds and necessary lacing wire or connectors are prepared and packaged with the gabion units.

8. Quality Inspection and Packaging:

   Standards: Throughout the entire process, rigorous quality control checks are performed at every stage. This includes dimensional accuracy, wire diameter, coating thickness (using X-ray fluorescence or magnetic induction methods), tensile strength, mesh opening size, and visual inspection for defects. Our products adhere to international standards such as ISO, ASTM (e.g., ASTM A975 for double-twist gabions), and EN standards, ensuring that every wire mesh baskets retaining walls unit meets the highest performance criteria. Once approved, the gabions are compactly bundled and packaged for shipment.
