The steel rebar for sale contains many sizes including 8mm, 10mm, and 12mm. the sizes mentioned are all available in our stock. One of the things that a supervising engineer should check in the workshop is the control of the reinforcement of the foundation, rebar, beam, or shear wall, and the first thing to check in this check is the size of the reinforcement. On the surface of the rebar, the tread sits around them, as it makes them stronger and engages the concrete to pour concrete around them, which is why they are useful. Therefore, the steel bars have accurate values in size and weight and are produced and sold in accordance with international standards, and their dimensions are also estimated according to this standard so that the final weight of the structure can be calculated correctly. However, each country has chosen a number of different standards for production in their factories. These are mainly available in two simple rib models from 12 to 36. 
Although it is not difficult to determine the size of the rebar, if there are several bars of similar size in the workshop, the rebar may be wrong, and the supervision engineer's size control may be accompanied by an error. Visual identification of rebar size: The most common method to determine the size of the steel bar is the visual inspection. Many engineers do it based on their own work experience, and they can know the size of the steel bar at a glance. But this method is not at all suitable for novice engineers, and there is no such authority given to supervising engineers in the regulations, and the percentage of errors and mistakes in this method is very high. 
Check the size of the rebar based on the size of the finger and a mental estimate: This method is a quick and professional method for experienced engineers and architects who already know the size of the knuckles, so they put their fingers on the rebar and can easily find the size of the rebar without the use of tools. This method is the best way to check rebar size without the rebar or contractor noticing, but it is certainly not an easy task to distinguish 18 out of 20 tie rods when they are only 2mm apart. 
12mm rebar
A3 type 12mm rebar or 12-rib steel bar is one of the most widely used steel structure building materials in construction engineering. The primary use of rebar is in concrete because rebar is used in structures as tensile members and to compensate for the tensile strength of the concrete as concrete itself has a very low tensile strength which is considered equal to zero in structural calculations. For example, a concrete beam is stretched under the influence of bending force, and since the tensile strength of the concrete is zero, the steel bars play the role of carrying the tensile force in the concrete beam. If the rebar 12 is used in a concrete element, it is called reinforced concrete or reinforced concrete. It is best to use ribbed rebar in concrete so that the tread on the rebar creates maximum contact with the surrounding concrete. Reinforcement grades in concrete elements are determined according to Iran Building Code No. 9 on the basis of two factors. The first factor is the required tensile capacity of the concrete elements, which depends on structural loads and seismic forces. 
The second factor to determine the rebar score is the density of the rebar in the section of the concrete element, which according to regulation should not exceed the limit. Rebar grade 12 means that the cross-section of the bar is equal to 12 mm. Rebar produced in Iranian factories has the standard number 3132 from the Iranian National Standardization Organization. According to the table of the Iranian standardization organization, the density tolerance should be between 4% and 8% of the density of each bar. The price of rebar 12 fluctuates a lot, usually, fluctuations in the dollar and the economic situation will strongly affect the price of rebar. Normally, after the rebar tonnage is determined, a provisional invoice is issued for the purchase of 12 rebars, but if the purchase tonnage is high, the final price will be determined based on the weight of the scale. 
There are two types of reinforcement in concrete columns, longitudinal reinforcement, and narrow reinforcement. Damping is used in concrete beams to increase the shear resistance of the beam. Reinforcing bars are used in reinforced concrete to compensate for the low tensile strength of the concrete. The steel used for this purpose in reinforced concrete structures is in the form of cables or rebars called rebars. Factory-made steel bars have different degrees of hardness depending on the amount of carbon used in the steel alloy. Based on this, rebars in the market are mainly produced in 4 types: non-ribbed A1 type, ribbed type A2, ribbed type A3 and ribbed type A4. 
rebar for sale
Many companies in the market have rebars for sale in their stocks and If you are planning to build a home or individual unit or to complete a construction project as an engineer, you need to know about buying rebar. Since the purchase of rebar in any quantity and size is considered an expensive purchase, it is necessary to know about rebar before and during purchase. A reliable and experienced advisor can help you make an informed purchase to avoid financial and time loss. Factory purchase: This method is suitable for customers who buy more than one trailer (equivalent to 24 tons capacity) and buy large quantities and seek the lowest rebar price. Although buying directly from the factory seems cost-effective, in some cases the factory due to insufficient daily supplies, long shipping times, difficulties in shipping and tracking orders, restrictions on minimum purchase quantities, inability to deliver directly to end consumers, etc. 
Wait. . Many people do not check this option when they buy. Purchase from the company: A hardware sales company is a suitable choice for customers who buy in small quantities. This type of purchase can provide customers with many benefits: You have no minimum purchase limit, you can buy rebar and even more. Another advantage of buying from the company is easy to access and shipping at a lower price. (You can easily buy rebar from the company closest to your workplace.) Among the disadvantages of buying from a company, we can also mention the limitations of buying in bulk, the purchase price compared to the factory and the limitations of storage.

10mm rebar
The composition of 10mm rebars is made of steel, also known as steel mesh. Its primary use is in concrete, as a tensile device to further strengthen and hold the concrete. The appearance of rebar 10 is simple concrete without steps on it. A simple 10-bar is generally good flexibility due to its relatively small diameter, so this bar is best used in situations where bending is required. Because concrete and steel used in simple rebars have high thermal coefficients, this may be another reason to use simple 10 rebars in buildings to minimize heat and temperature variations. 
In the general classification, simple reinforcement is divided into two categories:
- Simple rebar model,
- Simple coiled steel bars, each with its own purpose.
Size examples made from these two models are available on the building materials and equipment market in the form of 5.5 to 12 mm. The importance of using Simple 10 rebar, together with various examples on the building material market today, is the reason to introduce you to the uses and examples of Simple 10 rebar to build structures with high resistance. 
10 simple disadvantages of steel reinforcement
Since the majority of the 10 simple rebars are not completely pure steel, this leads to more concrete damage and destruction and rusting of the rebar. In order not to rust, the pH of the concrete surface must be greater than 12. Now, if the amount of concrete coverage is greater than usual, we produce concrete with a large width, which can be a threat to local conservationists. On the other hand, rust in steel causes a large pressure inside the concrete to enter its surroundings, which eventually causes it to crack, protrude, and even destroy its structure. Other problems and disadvantages of rebar are related to the head. Minor damage and scratches can be protected to some extent by covering the ends of the rebar with plastic protective sheets, but this covering does not prevent more serious risks. 
Ordinary steel rods are sold in different diameters, each serving a very different purpose. The main use of simple 10 rebars is in the manufacture of rabbits. The most common example of making a rabbit is the simple 10mm model. As we said in the previous section, the use of rebar is related to the problem. To fix it, the simple rebars are coated with epoxy resin so that they show greater resistance to corrosion during the transport and loading industry, the rebar installation phase, and the concrete casting process during the work. 
8mm rebar
A3 type 8mm steel rebar or A3 type eight ribbed steel bar is one of the most widely used steel structure building materials in construction engineering. The primary use of rebar is in concrete because rebar is used in structures as tensile members and to compensate for the tensile strength of the concrete as concrete itself has a very low tensile strength which is considered equal to zero in structural calculations. For example, a concrete beam is stretched under the influence of bending force, and since the tensile strength of the concrete is zero, the steel bars play the role of carrying the tensile force in the concrete beam. If A3 type 8-rib steel bars are used in concrete elements, it is called reinforced concrete or reinforced concrete. 
It is best to use ribbed rebar in concrete so that the tread on the rebar creates maximum contact with the surrounding concrete. Rebar scores are determined based on two factors. The first factor is the required tensile capacity of the concrete elements, which depends on structural loads and seismic forces. The second factor to determine the rebar score is the density of the rebar in the section of the concrete element, which according to regulation should not exceed the limit. Grade 8 ribbed steel A3 type means that the cross-section of the steel bar corresponds to 8 ribbed A3 type steel bar. The price of the A3 type 8-rib rebar fluctuates a lot. 
Usually, factors such as dollar fluctuations and economic situation greatly affect the price of rebar. Normally, after determining the tonnage of steel bars, an advance invoice will be issued for the purchase of A3 type eight-ribbed steel bars, but if the purchase tonnage is high, the final price will be determined according to the weight of the scale. There are two types of reinforcement in concrete columns, longitudinal reinforcement, and narrow reinforcement. Damping is used in concrete beams to increase the shear resistance of the beam. In addition, in order to better and faster identify the type of rebar in the construction shop, the steel mill will consider the different tread types when producing rebar for quick identification. 
They produce A1 rebar without tread, A2 spiral rebar, A3 cross pattern rebar, and A4 composite rebar. According to the building regulations, it is divided into hardness level of soft A1 steel bar, A2 semi-hard steel bar hardness level, A3 hard steel bar hardness level, and high resistance A4 steel bar hardness level. According to National Standard No. 3132, the minimum yield strength of the A1 ribbed steel bar is 240 MPa, and the minimum tensile strength is 360 MPa. A2 ribbed bars have a minimum yield stress of 340 MPa and a minimum tensile strength of 500 MPa. The minimum yield strength of the A3 ribbed steel bar is 400 MPa, the minimum tensile strength is 600 MPa, the minimum yield stress of the A4 ribbed steel bar is 500 MPa, and the minimum tensile strength is 650 MPa. Among other rebars on the Iranian market, we can mention stepless rebars. Wire-free rebar 8 is normally used for plastering, and wire-free rebar 6 is used as insulation reinforcement for building floors.
