Hot-dip galvanizing



metal protection against corrosion

Eskal Zinc LLC offers high-quality hot-dip galvanizing services in Uzhhorod (Zakarpattia region). The new plant is equipped with a production line with baths that allow galvanizing metal structures up to 7 meters long and with a capacity of 2000 tons per month.
We can galvanize:
– metal structures and metal buildings;
– power line poles (including high-voltage ones), mobile operator poles and antenna poles
– building metal structures, television and radio broadcasting masts and towers;
– lighting and searchlight poles, automotive parts, road fences and signs;
– steel round and shaped pipes, corrugated sheets;
– pipeline parts and hardware.

Eskal offers high-quality hot-dip galvanizing services for metal structures

Hot-dip galvanizing is the simplest and most cost-effective method of corrosion protection. Galvanizing extends the lifespan of metal structures by 50-70 years. Zinc coating is unique in that it provides not only a barrier protection but also electrochemical protection against corrosion.

The sequence of galvanizing steps

01
/08

Degreasing

01 stage

Degreasing is the removal of oils and contaminants. This process is carried out using a degreasing agent selected based on the type of contaminant.

Degreasing rinsing

02 stage

The rinsing procedure removes greasy substances and foam that settle on the parts from the degreasing bath.

Etching

03 stage

The etching operation involves cleaning the metal surface and removing the layer of oxides that form due to hot processing or unfavorable storage conditions.

Washing after etching

04 stage

Thorough rinsing is done to neutralize any potential residual acid and remove salts.

Fluxing

05 stage

This process is conducted to complete the surface preparation, protect the surface of the parts, and ensure good wettability with the molten zinc.

Heating and drying

06 stage

Moisture is evaporated from the surface of the parts and from hollow elements to prevent zinc from splashing due to water vapor when immersed in the furnace, as well as to avoid deformation of the parts.

Galvanizing

07 stage

The temperature of the zinc melt is 449°C, and galvanizing is performed within the classic range of 445 to 460°C.

Cooling

08 stage

Cooling takes place in the open air at the storage area, which is combined with the quality control (QC) section before packaging.

the company has already galvanized

The corrosion resistance of hot-dip galvanized coatings is 5-7 times greater than that of electroplated fasteners and approaches the resistance of stainless steel.

The coating self-repairs on damaged areas.

The coating is more resistant to chipping compared to polymer paint coatings with similar corrosion resistance.

Examples of Work

During hot-dip galvanizing, the steel item is completely immersed in a bath of molten zinc. The bath contains at least 98% pure zinc and is maintained at a temperature of about 449°C.

The molten zinc reacts with the iron in the steel to form a series of layers of zinc-iron intermetallic compounds. When the coating reaches the desired thickness, the items are slowly removed from the galvanizing bath, and excess zinc is removed by drainage, vibration, or processing in a specialized centrifuge.

The metallurgical reaction continues as long as the item remains at a temperature close to that of the bath. The items are then cooled either by immersion in a passivating solution or water, or they are left to cool in the open air.

Frequently Asked Questions

What parameters do you focus on during galvanizing?

To ensure a good result from the service, we focus on the following parameters:

– Quality of the zinc
– Quality of the steel
– Temperature of the molten zinc
– Immersion and extraction time
– Duration of immersion
– Cooling process

How long does the corrosion protection last after galvanizing?

Hot-dip galvanizing can extend corrosion protection for up to 50-70 years, providing both barrier and electrochemical protection against corrosion.

Is it necessary to subject galvanized metal to additional layers of protection?

There is no need for this, as the galvanized coating self-repairs on damaged areas, eliminating the need for repainting.
