Hot Rolled Coil is a type of steel coil that is produced by rolling steel at high temperatures, typically above 1700°F (926°C). This process is used to create flat steel products, which can be used in a variety of industries and applications. The hot rolling process involves passing a slab of steel through a series of rollers, which reduce its thickness and shape it into a coil. The resulting Gp base Colour Coil has a rough surface finish.
