The use of steel as a construction material has experienced spectacular growth in recent years. Although steel buildings have long been used in the commercial and industrial sectors, they are increasingly adorning the skylines of countries around the world.
The use of metals in construction began in the 18th century with the use of iron columns within the walls. Iron beams and columns became a common feature in large industrial buildings over the years. Ever since Sir Henry Basserner invented steel in 1855, it has become an integral part of bridges, pipelines, and even skyscrapers. Various difficulties related to the use of wood, such as its cost and the impact its use has on the environment, have contributed to the popularity of steel.
Steel buildings offer many advantages. They are generally built much faster than buildings using other materials; costs are typically lower compared to traditional construction methods; they are lighter in weight; they are easier to maintain; and carry a reduced risk of fire. In addition, steel is 66% recyclable, making it a particularly cost-effective and environmentally friendly alternative to any other building material. Above all, strength is a great advantage for steel. Steel structures can withstand unfavorable weather conditions such as hurricanes, strong winds, heavy snowfall, and even earthquakes. They are also resistant to termites, propagation, cracking, crazing and rot, which increases durability.
Although steel frame homes are still a bit more expensive than traditional wood buildings, the savings from being more energy efficient and having reduced maintenance make them an attractive alternative. Additionally, they can be given a conventional look by covering them with traditional building materials such as brick, siding, or stucco. There are several benefits, such as lower insurance costs (since the risk of fire is lower), lower assembly and labor costs, and lower material costs due to the prefabricated design. Modern technologies have also influenced the growth of the steel building systems industry as they can be used to improve design and manufacturing.
Steel building products, including steel frames, are made from recycled steel. No less than 28% of steel frames are recycled steel, which can then be recycled in turn. This is better for the environment than wood, as it is estimated that a typical 2000 square foot house uses the wood from around 50 trees. The same house, when built with steel, requires only about six scrapped cars.
