Maharsh Metal Heat Treatment

Dip Galvanizing Service, also known as Hot-Dip Galvanizing (HDG), is a process where steel or iron components are submerged in molten zinc to apply a protective coating. This zinc layer provides exceptional corrosion resistance, durability, and an attractive finish, making it a preferred solution for industries requiring long-lasting metal protection.

1. Complete Coverage: Ensures a uniform coating on all surfaces, including edges, corners, and hard-to-reach areas.
2. Corrosion Resistance: Protects metal components from rust and oxidation in harsh environments.
3. Long Lifespan: Offers decades of maintenance-free service in most applications.
4. High Durability: The metallurgical bond between zinc and steel withstands mechanical stresses and environmental conditions.
5. Eco-Friendly: Recyclable materials and a sustainable process minimize environmental impact.

1. Surface Preparation:
   • Degreasing: Removes grease, oil, and dirt.
   • Pickling: Eliminates rust and mill scale using an acidic solution.
   • Fluxing: Applies a flux solution to prevent oxidation before dipping.
2. Galvanizing:
   • The metal is immersed in molten zinc at approximately 450°C (842°F).
   • Zinc reacts with the steel to form a series of zinc-iron alloy layers, topped with pure zinc.
3. Inspection:
   • Thorough checks for coating thickness, uniformity, and adherence to standards.

1. Construction:
   • Beams, columns, and structural steel for buildings and bridges.
   • Roof trusses, handrails, and guardrails.
2. Infrastructure:
   • Utility poles, power transmission towers, and street furniture.
3. Industrial Equipment:
   • Pipelines, storage tanks, and conveyor systems.
4. Agriculture:
   • Fencing, gates, and irrigation systems.
5. Automotive and Transportation:
   • Chassis parts, frames, and components for long-term durability.
