Buildings that are constructed from steel generally use a type of steel called ‘mild steel’. It is very strong – you could actually hang two and a half African Elephants from a one inch diameter steel bar! This is a great advantage if you are erecting a building from the stuff.
Steel is also flexible. It can bend but it won’t crack – useful in places where there is extreme weather. Although steel structure very rarely collapse, the plasticity of the material means that it won’t suddenly give way, it will bend out of shape – this is an added safety feature meaning that anyone inside a steel building has plenty of chance to evacuate before the roof comes down! However, steel does lose this strength in a fire. In fact, it can lose almost half its strength at 500 degrees celsius – which happened in the World Trade Centre Towers in 2001. Steel used in buildings are therefore protected from fire or high temperature by wrapping with boards or spray on material.
Steel is used most often for high rise buildings, industrial buildings, warehouses, residential and for temporary structures that are quick to build and quick to remove again when no longer needed.
Let’s look at the different types of steel fabrication.
Conventional Steel fabrication uses piece of steel that are welded together. This can be done on site but is better if done partially in the workshop as this reduces the time it takes – and gives better working conditions for the erecting team.
Bolted Steel Construction starts in the workshop where pieces of steel are finished and painted, then transported to the build site and bolted in place. This is probably the most common type of construction with steel as it is more time efficient. Everything is made in the workshop then transported by lorry to the build site when cranes lift the pieces to where they need to be. The whole process is much faster than welding.
In some parts of Europe and North America, Light Gauge steel construction is sometimes used. These are much thinner sheets of steel that are bent to shape as needed and is often used for residential and smaller buildings.
