Construction technology has evolved rapidly over the past few years. Right from the techniques and technology deployed in construction, to the materials used – a lot has changed to become better and better.
However, this advancement in the building construction domain has left the builders and their clients more confused than ever. And right so – there are so many options to choose from, with little knowledge about what works the best for specific needs.
But worry not! In this post, we talk about one of the most important components of building construction – steel bars, and tell you about their different types their features and utility. So let’s get started!
5 Different Types of Steel Bars Used in Construction
1. Mild Steel Plain Bars
This is one of the simplest types of steel bars which is being used in building construction for a long time now. Mild Steel Plain Bars, as the name suggests, is characterized by plain outer surface unlike the ribbed structure displayed by other kinds of bars), and have relatively less tensile yield strength (which stands at around 40000psi).
This kind of steel bars is typically used in the construction of small building projects, which do not require a lot of steel strength. Further, these bars are cheaper, and hence the best suited from the economic point of view.
2. Hot Rolled Deformed Bars
Hot-rolled deformed bars are undoubtedly one of the most common types of reinforced steel bars used in R.C.C structures. These bars have high tensile strength (of about 60000psi) and are suited for all kinds of constructions. The steel provides great strength to the building construction.
In fact, the holt rolling process through which such steel bars are manufactured leads to the creation of deformities on the surface of the bras called ribs), which help create a storing bond with the concrete. This is a feature peculiar to the Hot Rolled Deformed Steel Bars and is not present in the type we discussed before.
3. TMT Steel
Well, TMT steel is the most widely used variety of steel bars in modern-day building construction. Along with unmatched tensile strength, TMT steel offers many features and properties that other steel bars do not. TMT steel is anti-corrosion, earthquake resistant, lightweight, and easy to assemble.
In fact, the very composition of the TMT steel and its manufacturing process make it the best that we have in the market today. Further, TMT steel comes in various sub virtues with varied features and strength, and you can choose the one that suits your needs the best.

4. Cold Worked Steel Bars
Cold Worked Steel bars are another type of reinforced steel that is obtained on the further processing of the hot-rolled bars. In this process, the hot-rolled bars are made to undergo the cold working process, during a cold-worked.
A reinforcement bar is obtained by letting the hot rolled steel bars undergo cold working. In the cold working process which is performed at room temperature, the bars will undergo twisting and drawing, which also leads to a reduction in the ductility of the steel.
So if you are looking for steel bars with that peculiar feature, Cold Worked Steel bars should be the ideal choice for you!
5. Prestressing Steel Bars
Prestressing steel bars are based on a different technology than all other kinds of steel bars. In this, steel bars are modelled as strands, which when deployed together in a construction frame, give rise to the Prestressing action. Strands of Prestressing steel bars are made of multiple wires, with a typical strand constituting as many as 2 to 7 wires. The tensile strength that these strands provide lies in the range of 250000 – 270000 psi, coupled with great flexibility.
Takeaway
Steel bars come in various types with varied features. However, if you have to choose the best and most reliable amongst them all, we would suggest you go with TMT Steel Bars only.
