Rebars in Iran are produced in different sizes based on the diameter of the cross-section, which the rebar size table is 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40 and 50 mm. .
These construction materials are used in different parts of the building including foundation, beams and columns. The size of non-treaded rebar is generally similar to ribbed rebar, and in fact, you can refer to the same numbers to know the types of simple rebar sizes.
The size of rebars used in beams and columns is selected depending on the plan designed by the building designer, however, in normal buildings, the minimum size of rebars for columns is usually not less than 20. Beams are generally reinforced with size 14 to 20 rebars.
The sizes of rebars in the foundation are usually chosen in such a way that the main and reinforcing reinforcements are usually 18 and 20 sizes and the transverse reinforcements are between 14 and 16 sizes.
Khamut rebar size
Khamuts used in beams, columns and foundations of the building are closed using a specific size of rebars. Khamuts are placed in the form of rings around the main bars of beams and columns. To choose the size of Khamut rebar in normal buildings, the smallest size, i.e. 8 or 10, is often used. Click to know the price of rebar 8.
Vault rebar size
Vault rebar has no structural use and is used in building foundations to hold the upper network of reinforcements. To choose the size of the vault rebar, you must pay attention to the depth of the foundation; In fact, we need more diameters for the rebar at greater depths. However, the diameter of the vault rebar is not less than 14 mm.

Rebar sizes in normal buildings
The amount and size of the rebars are different in the foundation and different floors, and the rebars should be purchased based on what is shown in the building plan. Based on the experience of the manufacturers, the 14th rebar can be considered the most widely used rebar size in the market, which is used more than other rebar sizes for the purpose of reinforcing concrete. One of the important factors affecting the use of this section is the price of 14 rebar compared to the size and requirements of reinforcement in normal buildings. In general, rebars of size 12, 14, 16 and 25 can be the most widely used rebar sizes in He knew ordinary buildings. It should also be kept in mind that you can use the experience of people active in the iron market to choose rebar in terms of quality and manufacturing plant.
Thermal rebar size
In the case of thermal rebars, it should be said that these types of steel sections have their own sizing. These rebars are used in order to prevent the stresses caused by the temperature change in reinforced concrete.
The use of thermal rebars in building construction should also be done according to the design engineer's opinion. However, the most common thermal rebars in normal buildings have a cross-sectional area of 4 and 5 mm in diameter. If you have a problem with rebar size, you can determine different sizes of rebar by using some methods.
