A steel bar is a long, cylindrical steel rod manufactured with ridges or deformations on its surface to enhance bonding with concrete and help increase the concrete’s tensile strength. This bar is mostly used to reinforce concrete structures and give the required tensile strength that is needed to counteract the weak tensile properties of concretes to help enhance their structural integrity and load-bearing capacity. The steel bars come in various grades, sizes, and configurations to be able to suit the different kinds of construction applications.
Steel Bar Prices
Steel bar prices can vary depending on the material’s grade, size, dimension, and length. On average, a single unit of steel bar can cost from 175.00 up to 705.00.

Advantages of Steel Bar
High Tensile Strength – Steel bars offer excellent tensile strength which makes them the perfect materials for reinforcing concrete and masonry structures, helping them withstand tensile forces and prevent cracking or failure.
Ductility – Steel bars possess a high degree of ductility which allows them to deform significantly before reaching their ultimate tensile strength. This property enables them to absorb energy and withstand dynamic loads, such as seismic or wind forces, without catastrophic failure.
Bonding with Concrete – The surface deformations or ridges on steel bars help enhance the mechanical bond between the steel and concrete, ensuring effective load transfer and preventing slippage or separation between the materials.
Corrosion Resistance – Many types of steel bars are manufactured with corrosion-resistant coatings or alloys to enhance their durability and longevity, especially when used in aggressive environments or marine structures.
Disadvantages of Steel Bar
Cost – Steel bars can be relatively expensive compared to alternative reinforcement materials, such as fiberglass or carbon fiber, especially if you opt for high-grade or corrosion-resistant steel bars.
Weight – Steel bars have a higher density compared to alternative reinforcement materials, which can result in heavier structures and increased dead loads, particularly in high-rise buildings or long-span structures.
Potential for Concrete Spalling – If steel bars are not adequately covered with concrete or if concrete quality is compromised, steel corrosion can lead to the formation of rust which can cause the concrete to spall or crack, reducing the durability and aesthetics of the structure.
FAQs
What is a steel bar used for?
Steel bars are mostly used in construction projects to provide concrete structures with excellent structural support and reinforcement.
What is a bar of steel called?
A bar of steel is commonly referred to as a steel bar or rebar.
Is steel bar the same as rebar?
Steel bars are designed to resist tension forces which helps bolster the concrete’s tensile strength. On the other hand, rebars are a type of steel bars characterized by their deformed shape that enhances the bond between concrete and steel.
Where are steel bars used?
Steel bars are used in various construction projects.
What are steel bars used for construction?
It is primarily used in construction projects, where they are embedded in concrete to help enhance tensile strength.
