Identification and marking
The type of identification needed for steel articles influences the recommended method of identification.
For permanent identification, recommended methods are:
- Heavily embossed markings
- Punched markings
- Welded markings
Before and after galvanizing: the recommended method is the use of heavily embossed metal tags, generally attached to the article via wire.
Prior to galvanizing: recommended methods are water-based paints or marking pens.
Identification methods not acceptable:
- Oil-based paints or marking pens
Oil-based paints or marking pens and adhesive residue from stickers cannot be fully or effectively removed by the normal pre-treatment performed during the galvanizing process and will generally result in ungalvanized areas on the article where the identification was located.
