what is simple rebar meaning
Generally, rebar without tread is called simple rebar. A lot of building projects use this product. As you know, there are two main categories of rebars on the market, rebars and ordinary steels, which have different properties.
There are three forms of ribbed bars on the market: helical, twill and composite. Also, reinforcement is divided into two categories: branched and coiled. Below, we have tried to familiarize you with the characteristics of simple rebar and its use in the industry.
Introduction of simple steel bar and its application in industry Typically, simple steel reinforcement is used in concrete to compensate for the low tensile strength of concrete.
The diameters mentioned in this product identification table are nominal diameters. Most simple rebars have a certificate sheet in which the product analysis is given.
The use of this steel bar can also be mentioned in industry and construction. Furthermore, for simple rebar welding, preheating conditions must be observed according to the Iranian national standard ISIRI 3131.
Simple rebar production steps to produce this rebar, first, ingots are placed in a furnace at a temperature of 1100 degrees Celsius using hydraulic jacks in specific rows, and when the ingots are placed in the furnace, they are ready to be rolled by eddy current at high temperature.
After reaching the desired temperature, the ingots are sent to the production line for rolling, after which the baked ingots are placed on rolls and guided to the next stage.
The roughing stage reduces the diameter of the ingots and increases their length in three stages. After the roughing stage, they go to the scissors stage to cut the produced steel bars to specific lengths without going through the steps of the frame for reinforcing the bars.
The rebar produced is cut under the packing guillotine according to the Iranian ISIRI standard and finally packed into bales.
Simple Rebar Standard This kind of rebar is called A1 rebar based on the old standard and 240 simple rebar based on the new standard.
Production of simple bars with diameters from 6 to 200 mm. Mechanical properties of unpatterned steel bars the tensile strength of the treadless rebar is approximately 360 N/mm2 and the yield strength is 240 N/mm2.
In terms of hardness, simple steel bars belong to the soft category. Simple rebar application This product is used as a reinforced concrete structural member or as a round bar in reinforced concrete buildings.
In some cases, this kind of reinforcement can also be seen in buildings as insulation reinforcement, which is a common mistake in building construction.
Also, among other uses of this product, we can mention industrial shafts and facades, while ribbed steel bars are used in construction and concrete structures.
How to Determine the Price of Simple Rebar To find out the price of this product, the easiest way is to go to the sales center and ask for the price.
But you need to know that there are many factors that affect the price of simple rebar.
The main consumption area of this product is the construction industry, so we conclude that the improvement or stagnation of the housing market has a large impact on the increase in demand for construction profiles and the price of steel bars.
In addition to the demand for the product, political and economic issues and international factors also affect its price.
The price of the product is basically determined based on the price of the raw material plus its production cost. In addition, transportation costs will directly affect the price of simple rebar.
The current highest price can be considered the price of Isfahan rebar, which is also the highest quality available.
Among other factories that produce this product, we can mention Zagros, Mianeh, Abhar, etc. The difference between unribbed and ribbed steel This type of rebar is called ribbed due to its ribbed surface.
Compared to standard steel bars, these goods have better structural qualities. Ribbed steel bars are used to increase the strength of concrete structures by 30% to 40%.
Due to the tensile, flexural and elastic properties of reinforced concrete, such steel bars are used in metal skeletons of concrete structures.
The calculation characteristics of rebar are surrender resistance Rebar spacer tensile strength Ribbed bar standard According to the old standard, these types of reinforcement were called A2, A3 and A4.
But under the new standard, these products are called 340 ribbed bars (spiral), 400 or double ribbed bars, and 500 or composite ribbed bars. The product comes in diameters ranging from 5.5 to 40 mm.
Check the standard type of reinforcement, there are 6 common types of rebar in the market, including the following European Carbon steel Galvanized epoxy coating glass fiber Stainless steel European rebar: This rebar includes carbon alloys, manganese, silicon, etc., mainly using manganese as raw material.
The cost of the item is the primary factor in its appeal. The resistance is small, and it is forbidden to use in earthquake-prone areas. Black rebar is another name for this item made of carbon steel. This product is not recommended as it does not rust easily in wet locations.
Epoxy Rebar: This black rebar has an epoxy coating to make it more rust-resistant. Galvanized rebar: This product is more resistant to corrosion than epoxy rebar and is therefore more popular. Of course, its price is also higher than that with epoxy coating.
