Ⅰ. Why we need the BS EN 10244-2-2001 Zinc or Zinc-Alloy Coatings standard

 

Welded mesh fence, High-Security fence, Double wire fence, Chain link fence, BRC Fence, Airport fence, Euro fence are Chiefence’s main products. All of them are made of galvanized steel wire. That is why we need a zinc or zinc Alloy Coating standard to keep stable quality.

 

Ⅱ. How many coatings options we have?

 

1. Pre-electric galvanizing + Powder Coating

2. Pre-electric galvanizing + PVC Coating

3. Pre-Hot dipped galvanized + Powder Coating

4. Pre-Hot dipped galvanized + PVC Coating

5. Pre-Galfan wire+ Powder Coating

6. Pre-Galfan wire+ PVC Coating

7. Hot Dipped Galvanized after welding only

8. Hot Dipped Galvanized after welding + Powder Coating

9. Hot Dipped Galvanized after welding + Powder Coating

 

Ⅲ. Which coating options can apply to the BS EN 10244-2-2001 Zinc or Zinc-Alloy Coatings?

 

1.  Pre-Hot dipped galvanized

2.  Pre-Galfan wire

3.  Hot dipped galvanized after welding

4.  Your requirement

l The coating class with a designation starting with A related to thick coatings(Generally Final Coating). Designations ending in B related to classes usually but not always obtained by(zinc coating) and subsequent drawing. Classes C and D are standard classes for low mass coating which are usually produced but not exclusively, produced by hot zinc dipping and then wiping.l A x 3 related to very high mass requirement three times higher than class A. Other multiples of class A are possible and these classes will be identified in the same way e.g A X 4

NOTE: 

  • Class A: usually zinc alloy coated at final size

  • Class B: usually coated and drawn after coating

  • Class AB: re-Drawn or coated with zinc-aluminum alloy after the final drawing 

  • china standard Galfan wire is Zn90% Al10%
