Rebars are one of the basic foundations of building construction, and as their price increases, the cost of construction also increases. Rebar is used in all construction areas, from the building floor to the roof and columns. A rebar is a steel rod that exists in many sizes and is used for concreting the building.

Concrete is one of the strongest materials that has a very high resistance to compressive forces and is so strong that a lot of force is needed to break it. But it has a big weakness that it does not have much resistance against rotational and tensile forces, and rebar plays a role in this.

The use of rebar increases the resistance of the building against tensile force, and in other words The rebar strengthens the concrete. One of the most important tasks of rebar in concrete pouring is that during an earthquake, it prevents cracks and breaks and ensures the safety of residents.

Using rebar in concrete reduces the required thickness of concrete and instead increases its strength. The use of rebar also reduces the cost of construction. As we said, rebars have many types and sizes that are made depending on their use. According to the appearance, rebars can be divided into two groups: simple and ribbed.
