TMT bars are hot treated bars that are high in strength used in reinforced cement concrete (RCC) work. Strength, ductility, welding ability, bending ability, and highest quality standards at international markets are the qualities that the latest induction of the MS steel bar posses. Few characteristics of TMT rebars are better ductility and malleability, high yield strength and toughness, more bonding strength, earthquake resistance, corrosion resistance, high thermal resistance, economical and safe in use, and no loss in strength at welded joints, etc. TMT steel bars are the number one preference for coastal construction where, where extreme humidity is a big problem. The outer surface of the TMT bars is hard and the core surface is soft. Their manufacturing process includes hot rolled steel wires passed through water. This makes the surface hard and keeps the core warmer softer. TMT bars and rods are all manufactured in the same process.
