TMT Bars at a Glance
Reinforcement Steel
Ribbed TMT bars used to reinforce concrete in slabs, beams, columns and foundations.
Multiple Sizes & Grades
Requirements are selected according to the structural design and the applicable specification.
Project & Bulk Supply
Support for requirements ranging from individual projects through to larger quantities.
What Are TMT Bars?
TMT stands for Thermo-Mechanically Treated. The bar is hot rolled and then rapidly cooled at the surface while the core cools more slowly, producing a hard outer layer around a softer, more ductile core. That combination is what makes TMT steel bars suitable for structural reinforcement.
In reinforced concrete, concrete carries compression while TMT reinforcement bars carry tensile and bending forces, so the two act as a single structural element. The ribs rolled onto the bar are not decorative — they key the steel into the surrounding concrete so load transfers without the bar slipping. Bar size, grade and spacing are set by the structural designer for each project.

Choosing the Right Bar
Four points that keep a TMT bar enquiry moving.
- Start from the drawing or bar bending schedule — bar size is a design decision.
- List every diameter the project needs, with the grade and standard named in the design.
- Convert running length into weight; TMT bars are quoted and dispatched by weight.
- Confirm delivery location and site access early, as both affect lead time.

Where Are TMT Bars Used?
Residential & Commercial Construction
Slabs, beams, columns and footings in houses, apartments, offices and retail developments.
Industrial Structures
Factories, warehouses and plant buildings where floors and bases carry heavy static and moving loads.
Foundations, Columns & RCC Work
Raft foundations, footings, pile caps and columns that carry the load path into the ground.
Infrastructure Projects
Culverts, retaining walls, bridge decks and public works exposed to weather and traffic loading.

TMT Bar Weight & Size Guide
Kilograms per metre, with D in millimetres
TMT bars are quoted and dispatched by weight, while drawings and bar bending schedules are prepared in running length. The industry converts between the two using a single approximation derived from the density of steel and the cross-section of a round bar. A 12 mm bar works out to 12 × 12 ÷ 162 ≈ 0.889 kg per metre, so a 12 metre length weighs roughly 10.67 kg.
Figures are approximate and should be verified against supplied material documentation.
| Diameter | Approx. kg/m | 6 m Weight | 12 m Weight |
|---|---|---|---|
| 6 mm | 0.222 kg | 1.33 kg | 2.67 kg |
| 8 mm | 0.395 kg | 2.37 kg | 4.74 kg |
| 10 mm | 0.617 kg | 3.70 kg | 7.41 kg |
| 12 mm | 0.889 kg | 5.33 kg | 10.67 kg |
| 16 mm | 1.580 kg | 9.48 kg | 18.96 kg |
| 20 mm | 2.469 kg | 14.81 kg | 29.63 kg |
| 25 mm | 3.858 kg | 23.15 kg | 46.30 kg |
| 32 mm | 6.321 kg | 37.93 kg | 75.85 kg |
TMT Bar Quality & Documentation
On a reinforcement order, quality comes down to the specification and the paperwork agreeing with each other.
Product Specification
Confirm that what arrives is the product described in your order, and that markings and packing correspond to the consignment documentation.
Grade & Size
Grade is a design decision, so check it against the order rather than assuming it. Measure diameter and length on a sample basis at receipt.
Material Documentation
Keep the documentation supplied with the consignment in your project records. Available documentation can be requested at the time of enquiry.

TMT Bar Questions, Answered
Common questions on TMT bar sizes, grades, weight and ordering. Not covered here? Reach us on WhatsApp or at sales@raipursteelmart.com.
What are TMT bars used for?
TMT bars work as reinforcement steel inside concrete, carrying the tensile and bending forces that concrete alone cannot. They are used in slabs, beams, columns, footings and retaining walls across residential, commercial, industrial and infrastructure construction — effectively every reinforced concrete element on a modern site.
Which TMT bar sizes are available?
TMT bar sizes are quoted as the nominal diameter in millimetres, and construction enquiries most commonly cover 8 mm to 25 mm, with larger diameters on heavier structures. Availability depends on our current product range, so share the diameters from your drawing or bar bending schedule and we will confirm what can be arranged.
How do I choose the right TMT bar size?
Bar size is specified by the structural design, normally through a drawing or bar bending schedule prepared by a qualified structural engineer. Smaller diameters typically serve as stirrups, ties and distribution steel, while larger diameters act as main reinforcement. Send us the drawing if you are unsure.
What is the difference between TMT bar grades?
A grade designates the strength characteristics of the steel, and the applicable standard defines how that grade is manufactured and tested. Different grades suit different structural and approval requirements. Which grade applies to your project is a design decision, so confirm it with your consultant and share it with the enquiry.
How is TMT bar weight calculated?
The common industry approximation is D² divided by 162, where D is the bar diameter in millimetres and the result is kilograms per metre. A 12 mm bar therefore works out to roughly 0.889 kg per metre. Actual weight varies with rolling tolerance and rib pattern, so verify against the documentation supplied with your consignment.
Can I request TMT bars for bulk project requirements?
Yes. Project, commercial and repeat requirements are supported, and dispatch can be phased around your site schedule rather than delivered in one consignment. Share the total quantity, the phasing you need and the delivery location, and we will plan the supply around that programme.
What information is required for a TMT bar quotation?
Five things move an enquiry forward quickly: the bar size or sizes, the grade and applicable standard, the quantity, the delivery location and your project timeline. If you have a bar bending schedule, sending it is faster than describing the requirement in words.
