SOCOVRAI®

Protect steel & iron againstcorrosion

• A Zn layer is chemically attached to the steel surface.

• Zn corrodes slower than iron and, thus, protects

Hot-dip galvanizing

• Zn corrodes slower than iron and, thus, protects iron from corroding.

• Very strong protection against corrosion.

• Different metals (Ni, Cr…) are attached to the base metal surface.

• Used for high-gloss applications.
