Hot Dipped Galvanised Coil: A Brief Overview

Galvanized coils are a widely used material in the construction and manufacturing sectors. One of the popular varieties of this category is the hot dipped galvanised coil. In this article, we will take a closer look at this material and explore its various aspects.

What is Hot Dipped Galvanised Coil?

The process of hot-dip galvanization involves coating a steel coil with zinc. This is done by immersing the coil in a bath of molten zinc at a temperature of around 450°C. The zinc layer adheres to the steel surface, creating a protective barrier that shields it from rust and other forms of corrosion.

The thickness of the zinc coating depends on several factors, including the thickness of the base metal and the duration of the immersion process. Typically, the zinc layer ranges from 50-275 g/m2, but higher thicknesses can be achieved if required.

Advantages of Hot Dipped Galvanised Coil

Hot dipped galvanised coil has many advantages when compared to other types of coating. Some of these advantages are:

1. Corrosion Resistance: The zinc coating acts as a protective barrier, preventing rust and corrosion from forming on the underlying steel.

2. Durability: The thick zinc coating on hot dipped galvanised coil makes it highly durable and resistant to wear and tear.

3. Cost-effectiveness: Although the initial cost of galvanising may be higher than other coatings, the long-term cost of maintaining and replacing corroded materials is much lower.

4. Aesthetic Appeal: Hot dipped galvanised coil has a shiny finish that gives it an attractive look and improves its overall aesthetic appeal.

Application of Hot Dipped Galvanised Coil

Hot dipped galvanised coil is used in a variety of applications, including:

1. Construction: It is used for framing, roofing, and cladding in buildings, bridges, and other structures.

2. Automotive: It is used to make car bodies, chassis, and other components.

3. Agriculture: It is used for fencing, irrigation, and other agricultural applications.

4. General Engineering: It is used for making various types of equipment, including machinery, appliances, and tools.


In conclusion, hot dipped galvanised coil is a versatile and reliable material that offers excellent protection against corrosion. Its durability, cost-effectiveness, and aesthetic appeal make it a popular choice in many industries. If you are looking for a reliable and durable material for your construction or manufacturing needs, then hot dipped galvanised coil may be the right option for you.
