The Importance of Structural Steel In Constructing Buildings Private

  Structural steel has become one of the most prevalent 



construction materials of the century, often seen as an extremely 



important component of modern buildings and housing. According to 



the World Steel Association, over 1,600 million tonnes were produced 



in 2016, 197 million more than the previous year. It’s become 



viable for any kind of project and offers several benefits, which 



many building plans rely on for structural safety.





    Availability





    The widespread adoption of steel has made it easy to find, both 



as a raw alloy and pre-made components. Fabricated parts will often 



be openly sold by suppliers (with many factories selling both 



locally and overseas), allowing beams and frames to be purchased 



directly.  Thanks to this, companies can work under tighter 



deadlines and access a supply of steel parts anywhere in the world.



    







    Steel parts can be ordered as soon as the architectural plan is 



agreed on, saving time that would be spent waiting for them to 



arrive at the site. This provides extra time to check measurements 



and find suitable storage, issues that could normally delay 



construction by several hours.





    







    Weight





    Its lightweight makes steel easy to transport over land and lift 



via a crane, reducing the amount of fuel wasted getting it to the 



site. In addition, this can make buildings far easier to take down: 



a prototype ProLogic warehouse was built at Heathrow to demonstrate 



how over 80% of the entire structure was reusable, which could be 



disassembled in a fraction of the time an average warehouse would 



take.





    







    Low weight can aid in moving and rebuilding structures, as shown 



with the 9 Cambridge Avenue warehouse relocation: the warehouse 



itself was dismantled and rebuilt 1 mile away, using almost no steel 



except the existing components. This added mobility and versatility 



makes steel a very desirable building material for structures that 



have extra land for expansion.





    







    Sustainability





    As the desire for eco-friendly buildings increases, steel will 



become more convenient for construction projects. It can easily be 



recycled and doesn’t need to be permanently disposed of, so old 



buildings or temporary supports can be repurposed into new projects 



as needed. Roughly 97.5% of all steel from UK demolition sites is 



recovered and reused, according to data gathered by Steel 



Construction.





    







    Recovered steel components that haven’t been damaged can be 



re-used in other projects, removing the cost of getting the alloy 



melted down and re-cut as a new part. If a building is being 



demolished and rebuilt, existing parts could be stripped out and 



repurposed to save money kept in storage for future projects or 



simply sold to another company as components (or raw alloy, if sold 



back to a steel fabrication company).





    







    Strength





    Due to its high strength-to-weight ratio, less steel is needed 



in a single support or beam, reducing material costs and improving 



its sustainable nature. It can withstand strong physical impacts and 



forces, keeping building occupants safe, but won’t wear away or 



need to be replaced afterwards. This extra strength can be retained 



through the design, rather than the amount of steel used. Steel I-



beams are often used in modern construction since they’re lighter, 



stronger and less wasteful than any wooden beam of the same size.





    







    The natural fire and rust resistance of alloy steel makes it 



viable for exterior structures, such as fire escapes or balcony 



supports – MIMA also suggest possible use as external walls to 



contain insulating materials.





    







    Price





    Modern regulations are very specific about how efficient 



construction should be: these rules often have the added benefit of 



cutting maintenance or material costs in the long run. Concrete 



remains more consistent compared to the varying price of steel, but 



the costs of repairing and reinforcing a concrete beam or pillar 



will usually make steel cheaper over a building’s lifetime.





    







    As mentioned earlier, steel is entirely reusable. It retains all 



of its properties, so a large amount of recovered steel could 



drastically reduce the cost of a new structure. A small study on the 



cost of a London office building revealed that steel composite was 



roughly 8% cheaper than concrete slabs across all ten storeys.
