Reinforcing Steel refers to TMT Steel bars that are used in RCC constructions for strengthening the brittle hard concrete and offering tensile strength to the construction. Steel is an alloy of iron and carbon and other elements. Because of its high tensile strength and low cost, it is a major component used in buildings, infrastructure, tools, ships, automobiles, machines, appliances and weapons
The properties of Reinforcing Steel are
1- Strength: The steel is strong as a material, due to uniform lattice structure at the atomic level.
2- Ductility: The ability of steel to be drawn into wires is quantitatively higher than other metals. This is affected by the proportions of the alloying materials in its composition.
3- Malleability: The steel can readily be beaten into sheets due to the intrinsic property of the alloy due to its lattice structure.
4- Weldability: Steel materials can easily be welded, as their melting temperature is within the limit of majority welders.
5- Durability: Steel products survive years of damage, wear and tear, and endure impacts before failures are observed.
6- Toughness: Steel as a material is tough, making it resistant to sudden impacts. Agni Steels’ TMT Steel rods possess tolerance up to 6.127-6.506 Kg/metres.
