Superior Anti-Corrosion Solutions for Airport Fencing in Tropical Climates
Why can our airport fencing mesh perfectly withstand hot, rainy, and salt-laden climates? The secret lies in the dual-layer surface treatment technology: Hot-Dip Galvanization + PE/HDPE Plastic Coating.
Detailed Content:
First Layer of Protection: Hot-Dip Galvanization – The Steel’s “Armor”
All steel components are immersed in a 450°C molten zinc bath. This process forms a robust zinc-iron alloy layer that tightly bonds to the steel surface, providing the following benefits:
Cathodic Protection: The zinc “sacrifices” itself by oxidizing first, thereby protecting the underlying steel—effective even if the coating is scratched.
Standardized Durability: A thick zinc coating of ≥70µm (microns) ensures rust prevention for over 10 years in general environments.
Second Layer of Protection: PE/HDPE Plastic Coating – The Weather-Resistant “Outer Shell”
After galvanizing, the product is coated with a dense layer of Polyethylene (PE) or High-Density Polyethylene (HDPE) via dipping or spraying methods.
Resistance to Chemical & Mechanical Corrosion: A thick plastic layer of 0.8mm – 1.2mm completely isolates the steel from sea salt, weak acids, chemicals, and UV rays.
Aesthetic Versatility: Available in standard colors such as grass green, blue, and warning yellow, complying with airport safety regulations.
