Hot Dip Galvanizing

Hot-dip galvanizing is the process of coating iron and steel with a layer of zinc by immersing the metal in a bath of molten zinc at a temperature of around 450°C.

Our company, KAPLANOGLOU S.A., undertakes the supply of whole Hot-dip galvanizing lines, equipment as well as chemicals.

Acid Degreasing

Our companies offers acid Degreasing Products, appropriate for the pretreatment of Steel items before Hot Dip Galvanizing.

These are mixtures of mixtures of acids, appropriate surface-actives  substances  and inhibitors, which remove oil, fat and paraffin from the metal surface.
These oils are emulsified and accumulated at the bottom of the tank of acid degreasing.
The inhibitors, that these products contain, protect  Steel  from etching .

Soak Cleaners

These are alkaline soaps, which are diluted with water  and at working Temperature 60-70 degrees Celsius remove polishing pastes, oils etc.  from  Steel items.

 

Pickling Additives

Our company can provide products which are added to pickling solution, based on Hydrochloric Acid or Sulfuric Acid and ameliorate  steel pretreatment.

  • Degreasing Additives

added in small amounts in acid pickling solutions (usually based on  Hydrochloric Acid)and  help the degreasing of the articles.

  • High Efficiency  Inhibitors 

-These are added in acid pickling solutions and protect Steel  from etching
-Elongate the life time of pickling solutions

  • Suppressing Acid Fumes Additives

-These are added in acid pickling solutions with Hydrochloric Acid and reduce the escape o Hydrochloric Acid vapours into the atmosphere
-Protect metallic parts in working area against corrosion
-Improve working conditions

 

 

Flux

 Crystallized or even anhydrous powder.

Passivation – Polymer

We can provide passivation products (polymer), specifically designed to protect  hot dip galvanized steel items against white rust corrosion.
It offers an environmental friendly alternative to products based on formulations, that contain fluoride, chromium and other heavy metals.
Typical coating weights have weight:  0,4-0,8gr/m2.
The galvanized steel coming from the zinc bath is dipped directly,  after galvanizing, in the passivation bath.
