TMT Bars
TMT - Thermo Mechanically Treated
TMT - Thermo Mechanically Treated bars also known as "reinforcement steel" are bars of steel used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and hold the concrete in tension. Rebar's surface is often patterned to form a better bond with the concrete. Their manufacturing process includes hot rolled steel wires passed through water.
This makes the surface hard and keeps the core warmer and softer.This helps in making the steel corrosion resistance and also increases its weld ability.
They are used in General Concrete reinforcements in high rise buildings,bridges & other concrete structures.
