TMT Bars: 8 Facts to Know


The basic framework of a building decides its strength. And TMT bars are the most important components that give structural strength to a building. This is the reason why TMT steel bars are mostly preferred for building earthquake-resistant structure. Here are some facts about TMT bars:

1. TMT Steel bars are fire resistant. They can withstand extreme heat and that’s why it’s highly preferred in the construction industry.

2. TMT steel bars are fatigue resistant. These bars can withstand extreme pressure and absorb shock. These bars have good bending and re-bending properties. TMT bars have a soft ferrite-pearlite core and a strong exterior. The soft core allows it to bend a bit under pressure while the strong outer core brings its back to its former shape. This quality makes them capable of resisting extreme pressure and seismic shock. There are a number of TMT bar manufacturers in the country. Among all, SRMB is considered one of the leading TMT steel bar manufacturers. To browse their products, visit

3. TMT Bars have excellent weldability. With high weldability, architects, and civil engineers can create futuristic structures and designs and that too without affecting the bar’s strength and the quality of the structure.

4. TMT bars have superior elongation power. This quality is defined by the ability of the TMT bar to deform before it breaks. Higher elongation power decreases the chances of greater damage to the structure. This quality is specific to TMT bars and makes them the best material for safeguarding the building from damages in earthquake-prone zones.

5. These are economic options. Yes. Compared to ordinary steel bars, TMT bars give you 20% stronger structure with the same amount of steel. As a result, the production cost of TMT bars is lower than conventional steel bars.

6. TMT bars are ductile. These bars available in many grades including Fe-415, Fe- 500 and 550. Higher grades mean superior strength. That’s the reason why major construction projects go for high-grade TMT bars.

7. These bars have great weldability. And this quality makes it possible for the architects and civil engineers to create innovative structures and designs. This doesn’t affect the strength and quality of the bar and the quality of the structure.

8. TMT bars have a unique manufacturing process. During the manufacturing process, the bars are chemically treated to make them resistant to corrosion and rust.


Planning to Build a Home? Know The Facts of Construction Materials


Construction materials are important factors in deciding the quality of the structure. If the construction materials are not carefully chosen, the safety and security of the concrete structure are endangered. So, when planning a construction, the materials must be carefully chosen to avoid any kind of mishap. From TMT steel bars to bricks, there are many construction materials that are widely used for building homes and multi-storey buildings.

Construction Materials-TMT Bars

Here are a few facts about the commonly used building materials:

TMT Bars

From homes to bridges, TMT bar is commonly used in almost all type of construction. The manufacturing method of TMT bar follows processes such as compressing, rolling them in the mill, heat treatment followed by an intense quenching process with Tempcore system. The quenching process hardens the surface of the TMT bars, leaving the core of the bars soft. This process makes the TMT bars extremely durable and delivers superior strength. Also, it makes the bars ductile and gives it high bendability. Moreover, the ribbed surface of the bars helps form strong bond with the concrete, thus providing extreme strength to the concrete structure. For these reasons, TMT bars are highly preferred in zones prone to seismic activities.


This is a commonly used building material. Concrete is manufactured by mixing binder (such as cement) and aggregate composites. There are many types of concrete such as Rapid-setting concrete, fluid-fill concrete, Portland cement concrete, Roller-compacted concrete, to name a few. Among all, Portland cement concrete is commonly used in construction work. This cement is made of cement, sand, water, and gravel. After mixing all these components together, the mixture is hardened. The solid mass thus obtained is knows as concrete. Concrete has very low tensile strength. However, it’s highly durable and ensures longevity of the building.


Bricks, be it of clay or mud, or of ceramic material, is one of the most basic and essential construction materials. No construction is complete without bricks. These are used to make walls, roofs, partitions and other components of a house or building. Bricks are made by burning clay, mud or ceramic material in a brick kiln and then drying them to make them hard. The most common kind of bricks used for construction purpose is fired bricks. It’s because these bricks have cavities and thus, dries at a faster pace. Bricks are reinforced using a mixture of sand and cement and are placed upon one another for making walls and other parts of a building.


Cement is basically used to bind and reinforce all the construction materials such as TMT bars and bricks together. Cement is of two types:

  • Hydraulic Cement: this type of cement has adhesive properties and sets well with water.
  • Non-Hydraulic cement: It is a cheaper alternative to hydraulic cement and doesn’t harden with water.

Hydraulic cement is widely used for construction purpose.

We hope that these points will help shed some light on the various construction materials and their unique properties.
