What is a Reinforcing Bar? Reo Bar sizes, price and grades

Reinforcing steel, commonly called ‘Rebar’, is a type of qualified steel essential in the construction of big and small office and residential buildings. In fact, even your driveway concrete slab cannot be constructed without it. Let’s explore the various reo bar sizes and grades as well as how much it costs.

Reinforcing Bar

Even though concrete alone can be compressed, it’s still not strong enough to hold together the weight of a whole building and stand firm on its own. Therefore, reinforcing bars or ‘reo bars’ are bars made of steel reinforcing bar used to supply tensile strength to the concrete. They are long and thin steel bars having a ribbed, that is, a ‘ribs-like’ pattern.

Choosing the right type of Reo Bar

When choosing the correct type of rebar, there are two factors that you must consider. The first and most important criteria should be the type of material used in the making of the rebar plus its quality. And secondly, its coating material. Apart from this, the size of your project and the grade of material that must be employed to provide the right level of strengthening and support is also a crucial requirement. After taking note of the above factors, there are various types of rebars that you can choose from. Some of these include the following:  


  • Stainless Steel Rebar: Reo bars that are used in the construction of bridges and roads. 

  • Galvanised Rebar:  Although galvanised rebar is the most expensive choice, it is still reinforcing steel’s best bar when it comes to anti-corrosive properties.

  • High Strength Deformed Bars, i.e. HSD Rebar 

Rebar grades

‘Grade’ essentially refers to the exact extent of quality or standard that the reinforcing steel best bar must carry to deliver the right results. In order to evaluate it, you must have a basic understanding of how the yield strength differs from tensile strength. 

While yield strength means the least stress that a material can bear before it begins to deform, tensile strength means the maximum stress it can handle before it gets permanently broken or damaged. 

These are named on the basis of the minimum yield strength that they can handle. Likewise, the minimum yield strength of a grade 40 Reo bar is 40 KSI, that is, 40 Kilopounds Per Square Inch. At the same time, the lowest yield strength of a grade 80 Reo bar will be 80 KSI.

Rebar size options  

Note that apart from the Reo bar size, you must also have a good idea about its grade and the type of bar steel that it uses to choose the best for yourself.

Here is a list of Rebar sizes that you can purchase. 

  • #3
  • #4 
  • #5
  • #6
  • #7
  • #8
  • #9
  • #10
  • #11
  • #14
  • #18

Among these, while the #3 size is the mildest and most cost-effective size option used for building concrete roads, driving areas, and patios, the #18 size is the largest and the strongest Reo bar size utilised for industrial areas and large buildings. 

Reinforcing Reo Bar prices 

Reinforcing Reo bar prices are calculated using the linear foot size. It does not include installation costs and depends on some critical features of the material, such as:

  • Bar steel grade 
  • The thickness of the rebar
  • Type of material used to make the rebar


Purchasing the right kind of reinforcing bars can be a tough task when you have no idea about how it works and what options the market has to offer. But you don’t have to worry anymore; Neumann Steel is here for your help. Contact us for more detailed information according to your needs.
