Hot-dip galvanization is a form of 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).
When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances.
Talk to anyone in the hardware and construction industries, and ask them about what is that one concern that drives them to the wall – (not literally of course!) In all likelihood, the answer will be “the quality, longevity, and performance of the metals in use.
Hot-dip galvanizing has come a long way since it was first invented 150 years ago. The popularity of the process is because of the many qualities and traits it endows steel with. Above all, hot-dip galvanizing is termed as steel’s “best friend” for it endows it with anti-corrosion properties.
At Hylite, we receive numerous inquiries and requests for improving the quality of their steel objects and structures, and we recommend our best-selling solution – hot-dip galvanizing. One of the foremost reasons why hot-dip galvanizing continues to receive increasing endorsement is because it is the only process that facilitates metallurgical bonding between two metals. The amalgamation ensures enhanced anti-corrosion and durability. In other words, hot-dip galvanizing is the secret behind steel’s agility, quality, function, and performance. If these are qualities that you’d like to infuse in your steelworks, then why not opt for hot-dip galvanizing, and let us do it for you?
The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel, with a series of distinct iron-zinc alloys. A typical hot-dip galvanizing line operates as follows:
Steel is cleaned using a degreasing solution. This removes oil/grease, dirt, and paint.
Galvanized steel is widely used in applications where corrosion resistance is needed and is considered superior in terms of cost and life-cycle.
Like other corrosion protection systems, galvanizing protects steel by acting as a barrier between steel and the atmosphere. However, zinc is a more electropositive (active) metal in comparison to steel. This is a unique characteristic for galvanizing, which means that when a galvanized coating is damaged and steel is exposed to the atmosphere, zinc can continue to protect steel through galvanic corrosion, it self-repairs when damaged, sacrifices itself to protect the base metal.
Our hot-dip galvanizing services are a bestseller because there are a lot of individual clients and companies that want to prolong the lifespan of their steel appliances and applications. Hot-dip galvanizing has earned a reputation and popularity because it helps steel to last up to 20 years. What’s more, the performance and quality stay intact throughout, and very little maintenance is required.
Galvanized Steel has versatile applications. It can be installed outdoors and indoors, wherever higher service life of the steel is required and corrosion protection is needed to maintain functionality of the product.
The galvanization process occurs through an electrochemical action, where the surface of a metal is coated with a highly corrosion resistant material such as zinc on steel or iron products. An alternate method is known as hot dip galvanizing. Where articles are submerged and then coated with hot zinc, this method is used to usually galvanize steel sheets.
We at Hylite Group offer our clients premium service as a recognized brand that provides hot dip galvanizing in Mumbai . Our staff work to ensure the quality of our products is top notch and we are a well-known name amongst galvanizers in Mumbai and also galvanizers in pune.
The list of items that can be galvanized varies and according to your requirements, items that belong in the household category such as buckets, tubs and other types of containers can be put through the galvanization process, thereby ensuring a long corrosion free life!
In the constructional and engineering fields, machine part, tools, tanks, ships, and even wires can be galvanized to ensure long term use.
There are several different methods in which the galvanization process can occur. Zinc is widely used to prevent corrosion and that too has multiple different types of zinc coating, each with its own set of unique characteristics.
Steel metal is a rather popular and common material that is utilized in various industry, to ensure that steel can be durable and long lasting, manufactures, and the constructional industry therefore, opt for galvanized products.
Most common methods are:
A coil-to-coil process that is used to bond zinc on layers of steel sheets, wires, or strips. The continuously moving ribbon applies a fine thickness of zinc on the sheets, and the thickness of the coating can reach up 1.70 inches to 72 inches, depending on your requirements. To prepare for this process, the material is annealed, a treatment process where metals are heated until they are glowing and then allowed to cool at room temperature, this is done to ensure that no foreign particles are attached to the articles in the process to undergo galvanization.
Sheets that have been galvanized using this process are used in the automobile industry for in car bodies, roofing for residential projects and piping.

Inspection of work before dispatch to the Galvaniser
Fabricated assemblies, casting and other components for hot dip galvanising should be inspected and any significant surfaces identified before dispatch to the galvaniser to ensure that the following points conform to design requirements. This may avoid costly rectification and delays at the galvinishing plant.
