Own Hot-dip Galvanizing

Do you need to galvanize parts?

Hot-dip galvanizing is the best way to protect steel against corrosion.

According to the general principle, the steel parts are coated with a layer of zinc by immersion in a molten zinc bath at ± 450 °C to protect them against corrosion.

Building on the research work of pioneers, including Luigi Galvani, the French engineer Stanislas Sorel invented the galvanized sheet as we know it in 1836.  Even though galvanizing is not a new process, it retains a modern quality by its approach to building sustainability.

Galvanizing involves eight stages:

  1. Degreasing removes dirt and grease.
  2. The first rinse makes sure the subsequent baths are not contaminated.
  3. Pickling removes millscale and other oxides from the surface to be treated.
  4. The second rinse has the same purpose as the first.
  5. Fluxing prevents re-oxidation of the steel prior to immersion into the zinc bath.
  6. Drying prevents zinc splashing during immersion.
  7. Actual galvanizing, during which the workpieces are dipped into a molten zinc bath at 450 °C.
  8. Controlled cooling.

As a result, hot-dip galvanizing provides unparalleled protective coating, excellent adhesion, impermeability and mechanical strength.
