🏭 Hot Dip Galvanization – Premium Corrosion Protection for Steel Structures
Hot Dip Galvanizing is the most reliable and long-lasting method of protecting steel from corrosion. In this process, steel components are dipped into a molten zinc bath, creating a metallurgically bonded zinc coating that defends the steel against rust, weather exposure, moisture, chemicals, and industrial environments.
At M. Siddique Sons Engineering Concerns (Pvt.) Ltd., we offer ASTM-standard Hot Dip Galvanizing for a wide range of steel products across Pakistan.
Our modern galvanizing facility, skilled technicians, strict quality inspection, and decades of industry experience ensure that every steel component receives a uniform, durable, and high-performance zinc coating designed for long-term protection.
✔ 25+ Years Rust Protection
Zinc coating provides long-term resistance against moisture, UV exposure, and environmental corrosion.
✔ Strong Zinc Bond — No Peeling or Cracking
The metallurgical bond is far more durable than paint or spray-on coatings.
✔ Zero to Very Low Maintenance Cost
Once galvanized, steel requires almost no maintenance throughout its life.
✔ Ideal for Outdoor & Harsh Environments
High humidity, rainfall, coastal regions, and industrial zones — HDG performs everywhere.
✔ Cost-Effective vs. Painting
One-time galvanizing offers far better lifespan and cost savings compared to periodic painting.
✔ Complete 360° Uniform Protection
Every edge, corner, and internal surface receives full coverage.

From small steel items to large-scale assemblies, we handle all kinds of galvanizing requirements.
We follow an internationally approved 5-step process to ensure superior coating and long-term protection:
1. Surface Cleaning (Degreasing)
In this stage, all grease, oil, dirt, and contaminants are removed from the steel surface. Proper cleaning allows zinc to bond strongly with the steel.
2. Pickling (Acid Rust Removal)
The steel is treated in an acid solution to remove existing rust, scale, and oxidation. This deep cleaning ensures a perfectly fresh surface for galvanizing.
3. Fluxing
The flux solution activates the steel surface and prevents oxidation before dipping. This ensures maximum adhesion between zinc and steel.
4. Hot Dip in Molten Zinc (450°C)
The steel is fully immersed in a molten zinc bath, allowing zinc to metallurgically bond with the steel. This creates a solid, uniform coating that protects the steel from corrosion for many years.
5. Cooling, Finishing & Quality Inspection
After dipping, the material is cooled and inspected for:
Coating thickness
Zinc adhesion
Surface consistency
Overall finishing quality
We ensure the coating meets ASTM A123 / A153 standards, guaranteeing long-term performance.
