What makes iron and steel widely used in building infrastructure?

Iron and steel are widely used in building infrastructure due to their strength, durability, and versatility.

Iron and steel are two of the most commonly used materials in the construction industry. They are favoured for their exceptional strength and durability, which make them ideal for use in structures that need to withstand heavy loads and harsh weather conditions. Iron and steel are also highly versatile, meaning they can be shaped and moulded into a wide variety of forms to suit different architectural designs and construction needs.

Iron is a very strong material, but it is also malleable, which means it can be shaped and formed without breaking or cracking. This makes it a great choice for structures that need to be both strong and flexible, such as bridges and skyscrapers. Iron is also resistant to corrosion, which is a major advantage in environments where the material may be exposed to moisture or other corrosive substances.

Steel, on the other hand, is an alloy of iron and carbon, which gives it additional strength and durability. Steel is even stronger than pure iron, and it is also more resistant to rust and corrosion. This makes it an excellent choice for use in structures that need to be extremely strong and long-lasting, such as buildings, bridges, and tunnels.

In addition to their strength and durability, iron and steel are also relatively easy to work with. They can be cut, shaped, and welded using standard construction tools and techniques, which makes them a practical choice for a wide range of construction projects. Furthermore, iron and steel are recyclable, which makes them a more sustainable choice compared to some other construction materials.

In conclusion, the strength, durability, versatility, and practicality of iron and steel make them widely used in building infrastructure.
