Hot Dip Galvanizing
The Galvanizing Facility has been fitted with totally up-to-date equipment supplied by the internationally recognized German company LOI-Thermprocess. This technology is being continually upgraded whenever new updates are announced.
We are a member of the American Galvanizers Association (AGA) and have a strong technical collaboration agreement with them.
The Hot Dip Galvanizing process complies with company standards and BS EN ISO 1461: 2022. However, the company can adhere to any Hot Dip Galvanizing international standard as per the customer's requirement.
The total production capacity of the plant is 6.2 MT per hour and runs 24 hours per day.
Hot Dip Galvanizing has proven to be the most stable method of preventing corrosion. The process works by metallurgically bonding the layers of zinc-iron alloy to the steel, becoming an integral component of the structure, rather than a mere surface coating.
A Hot Dip Galvanized coating provides three types of protection:
- Cathodic protection
- Barrier protection
- Zinc patina

Pros
The intermetallic layers are strongly bonded to the steel (3,600 psi) and harder than the base metal, offering excellent abrasion resistance.
If the hot-dip galvanized coating is damaged, adjacent zinc molecules will sacrificially protect the exposed steel until all the surrounding zinc is consumed.
The coverage of the surface is uniform and complete. All interior surfaces of hollow structures and hard-to-access recesses of complex pieces are effectively coated.
Cons
Pieces that do not match the size and shape of the Zinc kettle cannot be galvanized using the Hot Dip method.
The process can only be applied in the factory, and not on structures that are already fixed. Such structures would have to be dismantled and coated as separate components.
