Rolled Steel: A Gift to Modern Day Engineering

There is no doubt that steel has changed the dynamics of infrastructure and construction businesses completely. The idea of rolled steel has taken that feat to a whole new level. Rolled steel is not less than any precious gift to the modern times of engineering. It is an eco-friendly option, cutting the budget costs of the construction and helping our mother Earth sustain a healthy environment.

The idea of Rolled Steel-

The idea of rolled steel is derived from the art of metal rolling. Metal rolling is the art that human history has known from as early as 600 BC. Such historical evidence of rolling mills in several parts of the Middle East and South Asia have derived the path for these advanced hot and cold rolling mills of the present times.

Introduction to Steel Rolling Methods-

Steel rolling is mainly performed in two forms: Hot Rolling and Cold Rolling. Because of these techniques, ordinary steel can be modified into different shapes to serve the diverse range of engineering needs.

● Hot Steel Rolling:

First, let's talk about hot rolling. The steel is treated at really high temperatures (usually above 1000 degrees Fahrenheit) in hot rolling. Such high temperatures do not allow recrystallization of the steel. The hot rolling technique is used to make sheet metals consisting of plain and straightforward cross-sections, which can be prominently used where there is no strict need for precise surface quality and material strength. Its affordable price makes it a perfect choice to build rail tracks, metal buildings, truck frames, agricultural equipment, and many more. If there is a need for better material strength, the hot-rolled steel is made to pass through a pickling process. In this process, uneven scaling gets fixed by the sandblasting and grinding treatments.

● Cold Steel Rolling:

Cold Rolled Steel is better than hot-rolled steel in terms of surface dimension and other features. These types of steel are used where there is a need for high aesthetics and precision. 

Cold Steel Rolling includes four processes which are pickling, cold rolling, annealing and temper rolling. During pickling, the scales formed on the surface of hot-rolled steel get scraped out. After pickling, cold rolling is done to reduce the thickness of the steel strip. Next, annealing is done to relieve the stress developed in steel during cold rolling. Then comes the temper rolling, which provides the desired mechanical properties in the market-ready cold rolled steel strips.

There are different types of cold-rolled steel grades available in the market to serve diverse needs.

To get the finest quality of Steel, you should always buy from the trusted brands in the market, such as JSW ColdRolled Steel, India's leading producer of best quality cold rolled steel products.
