Hot rolled steel coil
Hot rolled coils are rolled at high temperatures and have good ductility, toughness and wear resistance, which is beneficial for subsequent processing and application.

Cold rolling refers to a rolling method that changes the shape of steel by squeezing it with the pressure of rollers at room temperature. Although the steel plate will heat up during the process, it is still called cold rolling. Specifically, cold rolling uses hot-rolled steel coils as raw materials, and after pickling to remove the oxide scale, it is pressure-processed, and the finished product is hard-rolled coils.
