In this factory, using modern technology, simple and ribbed bars, A2, A3 and A4, from 8 to 32 mm in size are produced in the form of branches.

The equipment of this factory, which was purchased from Danieli Italy, was put into operation after installation in February of 2012.

After years of experience in construction rebar rolling, after setting up its own steel making units in order to improve the quality level and development of its construction products, the company produces high diameter rebars according to the contract and according to the needs of the country’s construction industry for high strength rebars. A4(tread 500) (in order to save 25% in rebar consumption) started producing this product.

Taking a step in this way considering that the production of ingots in the Iranian market is usually limited to simple carbon steel without alloy elements, faced a serious obstacle, and in this complex, by setting up steelmaking units to produce steel ingots with alloy elements, it is possible to produce brick rebar that has both appropriate tensile strength and It was provided to have enough ductility, especially in high diameter rebars.

In the rebar produced by this company, by keeping the amount of carbon low and using alloy elements, as well as controlling, optimizing and fixing the rolling parameters such as speed, design of calibers and ingot temperature, the following benefits are guaranteed in the rebar produced by this company:

  • Maintain rebar welding capability
  • In addition to checking the required yield strength and final strength, the ratio of final strength to yield strength, which increases the ability to absorb energy before failure, increases the efficiency of rebar in seismic applications.
  • The percentage of increase in length is high, which is usually the percentage of increase in the length of the rebar of this company in each grade, for example, the percentage of increase in the length of the A3 rebar of this company is at the level of A2 to ensure the ductility and bendability of the rebar.
  • Accurate control of the size and shape of the rebar tread to ensure the rebar’s grip in the concrete, reducing its stress concentration and fatigue.
  • In order to achieve this accuracy, this company is equipped with a modern roller turning workshop.

In the Natanz steel complex, achieving the above benefits in rebar production is constantly controlled by using the most modern laboratory equipment to control chemical analysis, mechanical properties and metallographic structure.
