The development of construction methods in iron and steel was the most important innovation in architecture since ancient times. These methods provide far stronger and taller structures with less expenditure of material than stone, brick, or wood and can produce greater unsupported spans over openings and interior or exterior spaces. The evolution of steel frame construction in the 20th century entirely changed the concept of interior and exterior construction.

The steel frame has a profound impact on the exterior appearance of buildings, which no longer relies on load bearing masonry. The steel “skeleton” could simply be clad in a variety of other materials. Steel trusses also allow the construction of buildings with mighty internal spans. 90% of all metal that is refined today is iron. Iron’s toughness, resistance to harsh conditions and strength make it suitable for hard tasks. Adding iron to the construction gives strength and durability to the construction. It can withstand the environmental wear and tear for long. The ductile strength and hard of iron gives them strength to bear heavy weight.

Advantages of Iron and Steel Structures –
  • They are super-quick to build at site, as a lot of work can be pre-fabbed at the factory.
  • They are flexible, which makes them very good at resisting dynamic (changing) forces such as wind or earthquake forces.
  • A wide range of ready-made structural sections are available, such as I, C, and angle sections
  • They can be made to take any kind of shape, and clad with any type of material
  • A wide range of joining methods is available, such as bolting, welding, and riveting
