Galvanization
Galvanization provides anti-corrosion protection for steel tubes.
The galvanizing process provides the protective coating with enhanced adhesion, impermeability and mechanical strength.
Standard EN ISO 1461 requires a minimum thickness of :
- 55 µm for steel thicknesses between 1.5 and 3 mm
- 70 µm for steels between 3 and 6 mm thick
- 85 µm for steels thicker than 6 mm.
Treatment
Hot-dip galvanized to NF EN ISO 1461 standards.

The raw material used
The raw material used to manufacture our tubes is grade E235 Quality 2 (S235 JRH) steel with a scraped inner weld seam.
Our tubes comply with the regulations for longitudinally pressure-welded, cold-finished tubes, and conform to standard NF EN 10219.
The material used is suitable for bending, end flaring and hot-dip galvanization (Class I – II steels).
A 3.1 certificate for the material can be supplied on request.
