Steel is an indispensable part of construction. The possibilities presented by steel in the field of construction is not just limited to steel sections, but also as steel bars as reinforcement to cement concrete in construction of structures. The story of steel as a reinforcement presents a picture of innovation in the field of construction. Starting as iron as reinforcement to structures, to highly ductile mild steel to deformed bars (High yield strength deformed bars) and finally to thermo mechanically treated (TMT) steel bars, showcase an evolution of steel reinforcements to keep up with the needs presented by humans in the field of construction.
Reinforced steel bars have played a major role in the rise of the construction sector by evolving with the demands of the construction sector to provide safer buildings. The use of steel bars as reinforcement started from the 19th century. The rising demands led to the innovation of technologies that refined steel reinforced bars, used for constructing structures.
Steel has been a vital tool for mankind since its inception. Steel is the major component in almost everything starting from buildings, bridges, automobiles to pieces of machinery. Discovery of steel and it’s production dramatically changed the economic status of the world. Steel is an alloy of Iron and Carbon in which the carbon content is at 2% (Above 1%, it is classified as Cast Iron).
