Detailed Manufacturing Process Flow

The production of a high-quality Galvanized Welded Wire Mesh Gabion Box/Basket is a meticulous process, adhering to strict technical specifications and quality control standards. Our manufacturing workflow is designed to ensure superior product performance and longevity.

Key Materials:

• High-Tensile Steel Wire: Sourced from certified suppliers, conforming to ASTM A641/A975 or EN 10218-2 standards for tensile strength and ductility. Common wire diameters range from 2.0mm to 6.0mm.
• Zinc Coating: Applied via hot-dip galvanization (conforming to ASTM A90/A641 Class 3, or EN 10244-2 Class A/B) for exceptional corrosion resistance. For extreme environments, a supplementary PVC/PE coating is applied over the galvanized wire.

Manufacturing Stages:

1. Wire Drawing & Straightening: Raw steel rods are drawn through dies to achieve the desired wire diameter, followed by precision straightening to ensure uniformity.
2. Automated Welding: Wires are accurately positioned and resistance-welded at every intersection to form a rigid, square or rectangular mesh panel. Our CNC-controlled welding machines ensure consistent mesh aperture and weld strength. This process is critical for the structural integrity of the gabion.
3. Hot-Dip Galvanization: Post-welding, the mesh panels undergo thorough cleaning, pickling, and fluxing before being immersed in a bath of molten zinc. This creates a metallurgical bond, providing a thick, durable, and sacrificial coating that protects the steel from oxidation and corrosion. Coating thickness is meticulously monitored to meet specified standards (e.g., minimum 245 g/m² for heavy galvanized).
4. Optional PVC/PE Coating: For extended service life in highly acidic, alkaline, or saline conditions (e.g., coastal or industrial areas), a polymer coating is electrostatically applied and cured over the galvanized wire. This dual protection system dramatically enhances durability.
5. Cutting and Folding: Galvanized (and optionally PVC-coated) mesh panels are precisely cut to the specified dimensions for the gabion faces, diaphragms, and end panels. Panels are then folded or pre-assembled into the box/basket shape, often flat-packed for efficient transport.
6. Quality Control & Testing: Throughout the process, rigorous testing is conducted, including:
   • Tensile Strength Test: To verify wire strength conforms to standards.
   • Weld Shear Strength Test: Ensuring welds can withstand significant forces.
   • Zinc Coating Adhesion & Thickness Test: Using magnetic or eddy current gauges and bend tests to confirm coating quality per ISO 1461 or ASTM A90.
   • Salt Spray Test: For PVC/PE coated wire, simulating corrosive environments to assess protective capabilities.
   • Dimensional Accuracy: Ensuring mesh opening and panel dimensions meet design specifications.
   Compliance with international standards such as ISO 9001 for quality management, ASTM A975 for gabion specifications, and EN 10244-2 for zinc coatings on steel wire is strictly maintained.
7. Packaging and Dispatch: Finished gabion panels are flat-packed, bundled, and secured for safe and economical transportation, ready for deployment.

This meticulous process ensures that each Galvanized Welded Wire Mesh Gabion Box/Basket delivers an exceptional service life, typically ranging from 50 to 100 years depending on the environment and coating type.
