 You may have heard of the terms “cold rolled,” “hot rolled,” and “cold drawn” in the steel industry. Understanding how these types of steel are processed, as well as the proper applications for each, can help you choose the right steel for your project. Buying the right type of steel will save you time and money, as well as ensure your customers receive the best quality products.

Steel can be processed with a variety of machinery and at a variety of temperatures. In one of these processes, the steel is sent through rollers that shape the metal to a specific thickness. In comparing cold rolled steel to hot rolled steel, the main difference is the temperature at which the metal is processed. Cold rolling is performed when the metal is below its recrystallization temperature, which is the temperature at which the steel grain structure can be altered. Cold rolling is done at room temperature or near it.

As cold rolled steel is processed at this lower temperature, it requires additional pressure to form the finished product. Often, multiple passes through the rollers will be required to achieve the desired thickness. As a result of this process, steel has a high tensile strength, which means it is less likely to deform or break under tension.

Cold rolling does not melt steel, so the finished product will maintain a consistent thickness. Cold rolling also produces a more polished finish. It is ideal for products that require consistent thickness and a smooth, aesthetic finish, such as home appliances, metal furniture, and certain construction materials.

 What is a Cold Drawn Bar ?

There are two types of bright bars. The first is cold drawn and the second is peeled. Firstly in Cold Drawn Bright Bars the Hot Rolled Bars are pickled and drawn through a Tungsten Carbide Die as Cold Rolled, no heating is done, thus the name Cold Drawn Bright Bars. Secondly in Peeled / Turned Bright Bars, the Hot Rolled Bar is fed into a Turning machine and the surface is turned / removed to the required size. This is also a Cold process, no heat is required. Bright bars can be further ground for special applications.

Bright Bars have a smooth and a Bright surface with Accurate Tolerance on the Dia. Accurate Tolerance means the tolerance of the Dia is very restricted i.e 0.10 mm approximately depending on the size of the Dia and as per the customer’s specific requirement. These are the reasons why a Bright Bar has advantages over Hot Rolled Bar. Bright Bars can be used in automatic Machines for making Steel Components whereas a Hot Rolled Bar cannot be used. 

We have more advantages on producing cold drawn steel bars:

  • Big stocks of hot rolled round bars or wire rods as raw materials

  • Wide range of cold drawn steel bar sizes: from 10mm to 150mm
  • Different cold drawing medias powder or oil to get different surface
  • Straightening machines to get better straightness up to 0.5mm/m
  • Grinding and polishing machines to get better roughness upto 0.4um
  • Heat treating furnaces to adjust the mechanical properties
  • Full sets of testing equipment to test the sizes, mechanical properties  and microstructure.
  • Multiple packages to avoid broken packages and anti-rusty
