TMT (Thermo-Mechanically Treated) Bars are a critical component in modern construction, known for their high strength, flexibility, and durability. Manufactured using advanced thermo-mechanical treatment processes, TMT bars offer superior performance compared to conventional steel bars, making them ideal for residential, commercial, and infrastructure projects.
At Mangla Steels, our TMT bars are designed to provide structural safety, long service life, and cost efficiency, even under demanding construction conditions.
TMT bars combine a hard outer core with a soft inner core, giving them excellent tensile strength along with high ductility. This balance allows structures to withstand heavy loads, vibrations, and seismic forces without sudden failure.
They also offer better bonding with concrete, resulting in stronger and more reliable RCC structures.
Key Features
High Tensile Strength: Typically ranging from 500–600 MPa, suitable for heavy-load applications
Excellent Ductility: Elongation values of around 14–18%, reducing the risk of brittle failure
Superior Earthquake Resistance: Ideal for seismic-prone zones
Strong Bonding with Concrete: Ribbed surface ensures better grip and load transfer
Corrosion Resistance: Enhances structural life, especially in humid and coastal environments
