steel reinforcement barsReinforcing rods or steel reinforcing bars are used to improve the tensile strength of concrete because concrete is very weak in terms of tensile, but strong in terms of compression. Steel is used only as rebar because the increase in length of steel due to high temperature (coefficient of thermal expansion) is almost equal to concrete.
Types of steel reinforcing rods
The main types of steel rods used in construction are as follows:
Light steel rodThe surface of the steel bars is smooth, simple and round. They are available in different sizes from 6 mm to 50 mm. They are used in concrete for special purposes, such as dowels in expansion joints where the bars must slide on a metal or paper sleeve for shrinkage joints on roads and airport runways and column spirals. They are easy to cut and bend without damage.
For structural buildings such as bridges and other heavy structures, a light steel strip is not recommended due to the lack of a high connection between concrete and steel, slip and resistance.
What Factors Affect the Quality of Steel Reinforcement Bars in the Process of Production?
Investigating the special strategic importance for the development of the country’s economic plans: As you know, the production of rebars made of steel is one of the major commercial and strategic sectors of any country. Therefore, the design of the rebar factory should be cost-effective in this regard as well.
Check the import and price of rebar in the last 5 years: To produce any type of rebar, you need the desired alloy ingots made of steel. The alloy you are interested in may be produced in Iran or imported from other countries. Therefore, you should specify this issue and calculate exactly how many alloys you need for the desired production amount and check the amount of its import or production in the country and its price in the last 5 years so that by calculating its average, you can get a certain price for materials. Consider the raw material of the factory and consider it as a basic factor in calculating the cost of setting up a rebar factory.

What Is the Classification of Steel Reinforcement Bars in Constructions?
In the construction industry, more than any other steel industry plays a very important role in them. So, if this metal alloy did not exist, we would not have seen the development of these industries. Today, steel can be seen in all stages of a structure. It is used in the decoration of buildings from the construction of foundations and foundations to some delicate works. Even in the construction of many indoor appliances, this metal alloy plays a very important role. For each stage of building construction, there are different requirements for the use of steel. Each of which is made of a steel section.
Steel rebar is used to improve the tensile strength of concrete. Because concrete is very weak in stress. At the same time, its resistance to pressure is very high. Steel rebar is used to increase the strength of concrete. Because the tensile strength of steel is almost equal to that of concrete due to its high temperature (coefficient of thermal expansion).
The role of rebars in buildings
Rebar is one of the most important and widely used steel sections in the construction industry. The invention of this steel section caused a great change in the construction industry. And played a very important role in the construction of tall buildings and towers. The use of rebars is also used in the construction of columns, frames and stairs. And that it can be used to build a building foundation. One of the main applications of rebar in construction is to withstand the pressure of the building in the foundation and transfer it to the ground, or concrete foundation.
In ancient times, wooden rods were used instead of rebar. One reason for this was the unavailability of iron metal. Given that mining technologies and metal refining were not as advanced as they are today, the use of iron was not an easy and inexpensive task. But after the Industrial Revolution, it became possible to use this metal extensively in various industries. But the use of rebars was in the form of simple cylinders obtained by melting and shaping iron.
