Coating of metals
What this code covers
Use this class for coating of metals when the main activity includes Galvanising, including general (batch) hot-dip galvanising and Phosphate or chromate conversion coating. Check exclusions and nearby codes before applying it to a mixed activity.
Official NACE Rev. 2.1 labels and explanatory notes are imported from the source dataset. Plain-language explanations are shown separately so readers can compare interpretation with the source text.
No child codes; this is a class-level code.
- galvanising, including general (batch) hot-dip galvanising
- phosphate or chromate conversion coating
- cladding, electroplating, anodising, etc., of metals
- colouring of metals
- activities of farriers, see 01.62

What is NACE 25.51 used for?
Use NACE 25.51 for coating of metals when the main activity matches this scope: Use this class for coating of metals when the main activity includes Galvanising, including general (batch) hot-dip galvanising and Phosphate or chromate conversion coating. Check exclusions and nearby codes before applying it to a mixed activity.
What are typical examples for 25.51?
Typical examples include Galvanising, including general (batch) hot-dip galvanising, Phosphate or chromate conversion coating, and Cladding, electroplating, anodising, etc., of metals.
When might 25.51 not be the right code?
Review another code when the activity is closer to activities of farriers, see 01.62 and printing onto metals, see 18.12.
Which codes should I compare before choosing 25.51?
Compare 25.51 with 01.62 Support activities for animal production, 18.12 Other printing, and 22.25 Processing and finishing of plastic products when the activity description is ambiguous.
