The first step in the process when making sheet metal is hot rolling. Hot rolling means that steel is rolled from a 1200° warm steel compound. Hot rolled materials are available in a variety of grades and has a wide range of applications. It can be delivered both treated and untreated. Thickness from 1.5 mm.
Below are the most common hot rolled grades:
