It wouldn’t be a boast to claim that TMT bars are the backbone of our daily lives – from the homes we live in to the offices we spend our days working in to the bridges and flyover we passover during our commute – most modern structures get their strength from TMT steel bars interwoven through them.

The modern construction industry would undoubtedly be less robust and much more expensive without TMT bars.

What Is A TMT Bar And What Are Its Advantages?

Thermo Mechanically Treated bars or TMT bars are manufactured by using a unique technique that leaves them with a tough outer area and a soft inner core – this makes the TMT bar strong but also flexible.

Moira Sariya uses the advanced German “CRS” technology to manufacture its TMT bars. This cutting-edge technology exposes the steel to temperatures as high as 1100 degree Celsius. The steel ‘billets’ are then passed through rolling mills to give them shape and then quickly cooled with a process called quenching wherein high-pressure water spray cools the outside of the bars leaving the inner core to cool slowly on the cooling beds.

This two-layered cooling process makes the outer area of the bars extremely strong and gives the inner core more ductility.

Let’s look at the advantages TMT bars bring to the construction industry –

1. More strength and ductility – the high strength of the bars make them an ideal material to be used with concrete for making structures more robust. The unique ribbed pattern on the TMT bars also provides extra strength by bonding them more tightly with concrete. The ductility of the TMT bars makes them easier to work with, and pre-welded meshes can be made off-site reducing the overall construction time.

2. Corrosion-resistant – The TMT manufacturing process imparts anti-rust properties to the bars. Coarse carbides, which are the main culprits for corrosion in steel, are stopped from building up during the water-cooling phase making the structures made from TMT steel more durable.

3. Fire-resistant – due to its high thermal stability, TMT bars can withstand temperatures ranging from 400 to 600 degree Celsius; this ensures the building’s structural integrity even during a fire.

4. Earthquake proof – The soft core of the TMT bars imparts a high level of ductility – giving the structures made with TMT more leeway to manage dynamic and seismic loading.

5. Cost-effective– TMT bars have higher tensile strength and better elongation value, which basically means you need less steel for the same amount of construction. Apart from reducing the cost of raw material, this also saves cost on transportation and storage. TMT steel bars are also easier to manage on-site, which leads to a further cost saving due to reduced construction and fabrication time.

Applicability of TMT bars –

TMT bars have now become the gold standard in construction and are used widely in diverse projects, such as –

• Residential projects
• Highrise residential buildings
• Office / industrial structures
• Dams
• Long span bridges and flyovers
• Large structures such as Malls, Schools, Airports, Hospitals, etc.
• Underground structures
• Underwater or marine structures

If you want to construct a durable, cost-effective, and robust structure, then TMT bars should be your default choice of steel. However, it is important to buy from a reputable manufacturer such as Moira Sariya to ensure that you are working with a genuine, high-grade product.
