Understanding Hot Dipped Galvanized Mesh Fundamentals
Hot dipped galvanized wire mesh undergoes a zinc immersion process where steel strands are submerged in molten zinc at 450°C (842°F), creating a metallurgical bond. This industrial-grade coating provides 3-5 times greater corrosion resistance compared to electroplated alternatives. Typical zinc coating weights range from 90-275 g/m², with service lifetimes exceeding 25 years in moderate climates based on ASTM A123 testing protocols.
Technical Advantages in Extreme Environments
Third-party laboratory testing reveals critical performance metrics:
| Parameter | Hot Dipped | Electro-Galvanized | Stainless Steel |
|---|
| Salt Spray Resistance (hours) | 1,800+ | 250 | N/A |
| Tensile Strength (MPa) | 500-700 | 300-500 | 600-800 |
| Cost per m² (USD) | $8.50 | $6.20 | $28.40 |
The zinc-iron alloy layers provide sacrificial protection that maintains structural integrity even with surface scratches, unlike organic coatings.

FAQS on hot dipped galvanized mesh
Q: What is hot dipped galvanized mesh?
A: Hot dipped galvanized mesh is a wire mesh coated by immersing it in molten zinc, providing superior corrosion resistance. It is ideal for outdoor and industrial applications. This process ensures long-lasting durability.
Q: How does hot dipped galvanized wire mesh differ from regular wire mesh?
A: Unlike regular wire mesh, hot dipped galvanized wire mesh undergoes a zinc-coating process, making it resistant to rust and harsh environments. It lasts longer and requires minimal maintenance. This makes it suitable for fencing, agriculture, and construction.
Q: What are the benefits of Hot Dipped Galvanized Welded Mesh Panels?
A: These panels combine welded strength with zinc coating for enhanced structural integrity. They resist corrosion, weathering, and physical damage. Common uses include partitions, animal enclosures, and security fencing.
Q: Can hot dipped galvanized mesh be used in marine environments?
A: Yes, the thick zinc layer protects against saltwater corrosion, making it suitable for marine applications. It’s often used in docks, seawalls, and coastal fencing. Regular inspections ensure prolonged performance.
Q: How long does hot dipped galvanized mesh typically last?
A: Depending on environmental conditions, it can last 20-50 years due to its robust zinc coating. Proper installation and maintenance extend its lifespan. It outperforms non-galvanized or electroplated alternatives.
