Deformed bars
Deformed bars, also known as reinforcement steel or rebar, play a crucial role in construction. Let’s delve into the details:
What Are Deformed Bars?
Deformed bars are long, solid metal rods typically made from carbon steel. They come in various sizes, shapes, and grades.
These bars have ridges or deformations on their surface, which provide better bonding between the concrete and the steel.
Their primary purpose is to reinforce concrete structures by adding tensile strength, which concrete lacks on its own.
Why Use Deformed Bars?
Concrete has high compressive strength but relatively low tensile strength. It can withstand forces that push against it but can easily crack or break under forces that pull on it.
Steel bars are added to concrete to provide the necessary tensile strength and help it resist forces that might cause it to fail.
Deformed bars are typically placed in a grid pattern within the concrete structure, forming a reinforced concrete framework. This evenly distributes forces, preventing any part from bearing too much weight and potentially failing.


Sizes of Deformed Bars for Construction Work:
The size of steel bars used for construction work depends on the specific application and project requirements.
Common sizes of deformed bars include:
- 1.6mm diameter steel bar
- 2.8mm diameter steel bar
- 3.10mm diameter steel bar
- 4.12mm diameter steel bar
- 5.16mm diameter steel bar
- 6.20mm diameter steel bar
- 7.25mm diameter steel bar1
