Iron and steel are integral components in every construction which provides strength to the structure and make it capable of tolerating extreme weather and damaging forces of nature. They need to be of supreme quality as the quality of construction must never be compromised as when natural calamities strike, it's the houses that provide shelter. Structural steel and angle steel are just two of the most essential reinforcement required in every building. They're used in building columns, beams and the roof, that needs to sustain the load of the whole construction. Steel holds so much importance due to its attributes like strength to weight ratio, flexibility and being rust free. After 100 years of its invention, no structure can be fathomed with no steel. When it's a high rise construction, war boats or long pipelines, steel is in each such thing.
