Galvanised vs Mild Steel
Galvanised vs Mild Steel

Galvanized steel and mild steel are two popular materials used in construction, manufacturing, and various other industries. While they share some similarities, they also have distinct differences that make them suited for different applications. In this article, we will explain the differences between galvanized and mild steel, their properties, and their uses.


Why is galvanising better than painting.jpg


Galvanized steel is a type of steel that has been coated with a layer of zinc. The process of galvanizing steel involves immersing it in a bath of molten zinc, which creates a protective layer over the steel. This layer of zinc helps to prevent the steel from rusting or corroding, making it an ideal material for outdoor use. Galvanized steel is also more durable than mild steel, making it suitable for heavy-duty applications.

Mild steel, on the other hand, is a type of carbon steel that has low carbon content, typically below 0.25%. This makes it a relatively soft and malleable material, making it easy to shape and form. Mild steel is also inexpensive, making it a popular choice for a wide range of applications. However, it is not as strong as galvanized steel and is more prone to rusting and corrosion, especially in outdoor environments.

In terms of properties, galvanized steel is much more durable and resistant to corrosion than mild steel. It can withstand exposure to harsh weather conditions, making it suitable for outdoor applications such as roofing, fencing, and structural support. Galvanized steel is also resistant to fire, making it ideal for applications where fire protection is important. However, galvanized steel is more expensive than mild steel, which may make it less suitable for some applications.

Mild steel, on the other hand, is more ductile and easier to work with than galvanized steel. It can be easily welded and formed into various shapes, making it ideal for applications such as pipes, sheet metal, and automotive parts. However, mild steel is also more prone to rusting and corrosion, especially in wet environments. It may require regular maintenance to prevent rust and corrosion from developing.

In summary, galvanized steel is a more durable and corrosion-resistant material that is suitable for outdoor applications where rust and corrosion are concerns. Mild steel, on the other hand, is a more malleable and ductile material that is ideal for indoor applications that require shaping and forming. Both materials have their own unique properties and are suited for different applications, so it is important to choose the right material for the job based on its specific requirements.
