Each production step is governed by rigorous quality protocols:
- Steel rod traceability (Heat No.), surface purity analysis
- Welding strength per ISO 15614-1
- Coating thickness - minimum 40μm (test per ISO 2178)
- 48/96/240 Hour Salt Spray Test (ISO 9227)
- Dimensional and appearance inspection (ISO 2768)
1. Outstanding Corrosion Resistance — The hot dip process produces a metallurgical bond between zinc and steel, creating a barrier with self-healing abilities that protect even when cut or scratched.
2. Extended Lifespan: 15-30+ years service in most outdoor, marine, or industrial surroundings (ref:
Galvanizers Association - ISO 1461 FAQ)
3. Superior Mechanical Bond: Joints are welded, not twisted — giving excellent impact/tear resistance for perimeter, cages, security fencing.
4. Customizability: Wide range of aperture size, wire diameter, panel sizes, can be prefabricated or rolled.
- Environmental Safety: Zinc used is recyclable; meshes are sustainable and non-toxic (meets EU RoHS directives).
- High Weld Shear Strength: Resistance-welded mesh meets industrial loading/impact requirements.
- Low Maintenance: Total cost of ownership is up to 64% less than that of regular painted or electro-galvanized mesh (Research: Construction Industry Institute, 2022).
- Certification/Compliance: Many suppliers (incl. tikemetal.com) are ISO 9001, ISO 14001, and CE certified.

7. FAQ: Professional Terminology & User Concerns
Q1: What does "Hot Dipped Galvanized" mean for welded wire mesh?
Answer: It refers to the process of immersing welded mesh in molten zinc (~450°C), ensuring each surface, corner, and joint is completely sealed by a thick, robust zinc-iron alloy layer, yielding maximum weather and corrosion resistance. Unlike electro-plating, this method leaves no bare areas at welds.
Q2: What wire materials are commonly used?
Answer: Typically, low carbon steel grades (such as Q195, Q235 per GB/T 343 or ASTM A36), with options for higher-tensile or stainless steel for critical/security usages.
Q3: What are mesh opening and wire diameter, and why are they important?
Answer: Mesh opening refers to the clear space between wires (e.g., 25mm × 25mm); wire diameter (e.g., 2.5mm) affects strength, weight, and flexibility. These determine suitability for intended loads and particle filtration sizes.
Q4: What international standards apply to HDG welded mesh?
Answer: Key standards include ISO 1461 for hot-dip coating, ISO 15614-1 for welding qualification, and ASTM A123 for material and coating quality.
Q5: How is the corrosion resistance of HDG mesh tested?
Answer: Salt-spray (fog) corrosion tests (ISO 9227), adhesion, thickness (ISO 2178), and impact/peel adhesion checks are standard for qualifying every batch.
Q6: Is installation of HDG welded mesh different from other meshes?
Answer: While physical fixing is similar (panels/rolls attached with clips, ties, or brackets), additional grounding, edge sealing, or HDG-compatible hardware is recommended for full system longevity.
Q7: What is the warranty and after-sales service for projects?
Answer: Leading suppliers offer 10-year+ anti-corrosion warranty, free technical guidance, and fast inspection support (see
Tike Metal's service policy).
