Steel building is a metal structure utilised for the external shield and internal assistance. Steel buildings are used for a wide range of purposes including living space, office space and storage. They have developed into definite types depending on their uses.

Steel buildings gained popularity near the beginning of 20th century. Their application became more prevalent during World War II and considerably extended after the war. Use of steel in construction has seen an exceptional growth in the past few years. Even though have been employed in the industrial and commercial sectors for a longer time, their demand is progressively rising amongst many countries all round the world. In the recent years, steel buildings have become widespread as their competence have extended with the availability of superior computer aided designs and programs.

Some frequently used steel buildings are arch, straight-walled and clearspan. Arch and Straight-walled refers to the external shape of the building. Arch buildings are the most structurally sound and cost effective types of steel buildings. They are widely used in the agricultural industry. However, Straight-walled buildings present more practical space as compared to the arch buildings. These buildings are easier to combine into established architecture and are commonly applied for office space.

Clearspan refers to the inner construction of the building. Clearspan buildings make use of the strong support beams, thus derogating the need for internal column support. Clearspan buildings can be used a public arenas and can also be utilised to store commercial aircraft.

The modern steel building comprises of many individual sections that have developed over the time. With the availability of Computer Aided Design, steel buildings have turned into a much safer construction. The maximum snow and wind load have increased in particular, with the more precise calculations offered by CAD.

These advancements have led to a more proficient manufacturing process as most steel buildings are assembled. The smaller steel buildings are easy enough to be constructed, but the larger steel buildings entail specialized construction to ensure accurate assembly.

Steel buildings provide many benefits. Some of the main steel building advantages are as follows:

1    They are normally constructed much quicker than buildings utilising other materials. Steel buildings are also lighter in weight.

2    The costs involved in operations are comparatively lower to the conventional building methods.

3    They are easier to preserve and carries a reduced fire risks.

4    In addition, steel is an environmental friendly and cost effective material due to the fact that it is 66% recyclable. This makes it superior to the other existing materials for construction.

5    Above all, strength is the most important factor of steel. Steel buildings can withstand adverse weather conditions such as high winds, heavy snow, hurricanes and even earthquakes.

6    Steel buildings provide an increased durability since it is resistant to cracks, creeping, splitting, rotting and termites.

Steel framed buildings are certainly more energy and cost efficient as compared to the other customary buildings. They entail reduced maintenance and provide an attractive alternative.
