Iron alloys are treated in factories to turn them mostly into iron bars of different shapes and sizes for various applications. Half Round Bright Bar is also a form and that too a popular one. Although tubes, pipes and sheets are also some popular shapes, none of them is called bars. Half Round bright bar manufacturers create these forms of iron products through the process called rolling and or extrusion. The manufacturers also cut them at various intervals to meet the customized needs of their customers.
Half Round bright bar manufacturers make or rather create the bars using two processes mainly. While one is known as Turned (in other words Peeled), the other method is known as Cold Drawn. Round bright bars are created by further treating hot-rolled bars. Which is why in the Turned or Peeled process, as the literal meaning of the term. Hot-rolled bars are passed through a machine that pulls off the exterior of bars till the required diameter is reached.
On the other hand, the Cold Drawn process used by the Half Round bright bar manufacturers makes the hot half-round bright bars pass-through Tungsten Carbide Die to achieve better polish on the surface. Also, the bars in this process are treated to clean polish them, free of all the impurities. These treatments make the bars well-polished, clean and better wear-resistant. And because the process requires no heat for drawing the Half Round Bright Bars, it is known as the Cold Drawn method.
Due to its polished shiny surface & accurate tolerance, Round Bright Bars have better attributes adding to the advantages and thus are preferred over hot-rolled ones. Some of the industries from where the Half Round Bright Bar Manufacturers get the most amount of orders are the Chemical, Food Processing, Fabrication, Paper, Water Supply, Oil & Gas and many more.
