Materials and Surface Treatments
Electro-galvanized:
Thin zinc coating; suitable only for dry indoor environments; not recommended for long-term outdoor projects abroad.
01
Hot-dipped Galvanized (HDG) (Recommended):
Thick zinc coating; rain-resistant and corrosion-resistant; suitable for general outdoor use.
02
PVC/PE Coated:
Primarily green or black; aesthetically pleasing with enhanced corrosion resistance; suitable for residential areas and scenic spots.
03
304/316 Stainless Steel:
Highly resistant to salt spray; suitable for coastal areas and corrosive chemical environments; higher cost.
04

FAQ
Q: What is the difference between electro-galvanizing and hot-dip galvanizing? What is their service life?
A: Electro-galvanizing: Features a thin, shiny coating with limited corrosion resistance; suitable for dry climates or short-term use, with a lifespan of approximately 5–10 years.
Hot-Dip Galvanizing (HDG): Involves dipping the wire into molten zinc to form a thicker, rougher gray coating; offers 3–5 times the corrosion resistance of electro-galvanizing and is suitable for long-term outdoor use, with a lifespan of 15–30 years.
PVC/PE Coating: Adds a plastic layer over the galvanized coating for extra protection; the lifespan can reach 20–30 years.
Galfan (Zinc-Aluminum Alloy) Coating: A coating that outperforms hot-dip galvanizing-especially in coastal or high-salinity environments-typically lasting 2–3 times longer than standard hot-dip galvanizing.
Q: What is the Minimum Order Quantity (MOQ)?
A: For standard specifications, the MOQ is typically 5 tons or one 20-foot container (approximately 15–18 tons); small-batch trial orders can be negotiated.
For customized specifications, the MOQ is generally higher, such as 5 tons or one 20GP container.
Q: What zinc coating weight should be selected for coastal or tropical regions?
A: Tropical regions: Hot-dip galvanized products with a minimum coating weight of 50g/m² are recommended.
Coastal regions (within 10 km of the ocean): Hot-dip galvanized products with a coating weight of 60g/m² are recommended, or hot-dip galvanized products with an additional PVC coating. Electro-galvanized products are not suitable for outdoor fencing.
