Manufacturing Process: Step-by-Step Flow & Quality Control

0.5-4.0mm Wire 2×2 4×4 8×8 Hot Dipped Galvanized Coated Welded Wire Mesh Roll manufacturing process

Wire Rod Preparation – Quality controlled low-carbon steel rods (Q195/Q235).
Wire Drawing & Straightening – Down to specified diameter (0.5–4.0mm), ensuring uniform tensile strength and ductility (acc. to ISO 9044).
Welding Grid Formation – CNC mesh welding (spot-welding) for strong fusions at every crossing point.
Hot Dipped Galvanizing – Coated in molten zinc bath (425–450°C, per ASTM A641), guaranteeing anti-corrosion at grain boundaries.
Surface Smoothing & Quality Tests – Automated leveling, thickness check, adhesion testing, salt spray test (≥800hrs: SGS-certified), visual inspection, and random load tests.
Cutting & Rolling – Mesh is sheared to preset rolls; each roll is individually packed for shipping.

*Each production lot is sampled & tested for tensile strength (≥550Mpa), plating thickness, and mesh aperture tolerance (±1.5%).

Key Material and Technical Advantages

Corrosion Resistance: Hot-dipped galvanized coating provides superior protection even in marine or acidic industrial environments, tested to withstand >800hr salt spray test (per ISO 9227).
Precision Control: CNC mesh welding yields consistent mesh size and strength distribution (mesh deviation <±2mm).
Mechanical Integrity: Each joint withstands ≥500N tensile, exceeding EN 10223 standard for fencing and structural mesh.
Adaptability: Customizable roll length, width, mesh size, and coating for project requirements.
Certified Compliance: Manufactured per ISO 9001:2015 QMS, SGS, and third-party tested for coating adhesion and mechanical load.
