What is hot dip galvanization?

✅  It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 449 °C (840 °F)

✅ This is what makes a tank 100% rust free for lifetime 

✅  It is intended to have a long service life that is easily inspected and self maintaining.

✅  Famous applications of Hot dip galvanization are railway structures, mordern buildings & in fact, this process is used by the Indian & U.S. Navy to create all of its ships

Benefits of HDGI

✅ Extremely Long Life Galvanized coatings on steel can last in excess of 50 years.

✅ There is Less Maintenance Required 

✅ Reliability The base metal needs to have a standard minimum thickness otherwise the metal deforms during the hot dip process. So, the manufacturers cannot get away with a thin metal base that maintains high quality of the tank.

✅ Tougher Coating & Automatic Protection for any Damaged Areas Hot dip galvanising process gives the tank outstanding resistance to any physical damage. As an added benefit, small damaged areas do not need touching up as they get coated with additional metallic zinc layer. 

✅ All Over, Complete Protection With hot dip galvanising, all parts of the fabrication being galvanised is coated, and hence protected, even sharp corners, recesses, or what could normally be inaccessible areas.

✅ No other corrosion protection coating can offer the same protection to your tank.
