The history of reinforced steel

The history of reinforced steel fe415 rightsteel

The construction of a building is virtually incomplete without reinforcement. In construction, Steel is the primary alloy used for reinforcement. There is a reason for that because as we know that concrete is used for the construction of the building, even though it provides the compressive strength, it has weak tensile strength for withstanding induced forces. Therefore by combining reinforced bars, it provides the tensile strength for concrete to withstand induced forces. Also, The properties of thermal expansion for both steel and concrete are approximately the same which is why steel is used as reinforcement.

Reinforced steel bars or rebars has become the preferred standard for construction of building structures, bridges and many other commercial structures. The most popular among them is the Thermo Mechanically Treated ( TMT) reinforced bars. About 35% of the total steel production in the country was accounted by the reinforced steel industry. Usage of high strength TMT steel rebars has ensured rapid growth within the construction sector.

Reasons why TMT bars are better than HYSD bars

While TMT stands for ‘Thermo Mechanical Treatment’, the name is basically their process of protection and HYSD means ‘High Yielding Strength Deformed’ which is their main characteristic when compared with other rods. HYSD bars can be further divided into Torsed / twisted steel (TOR Steel Bars) and Cold Twisted Deformed Steel Bars (CTD Steel Bars).
