Products of this type are produced by passing steel slabs, at extremely high temperatures, through a hot-strip mill. The hot-strip mill compresses the slabs, which are typically about 250mm thick, between horizontal rolls with a progressively smaller space between them (while vertical rolls govern the width). This produces a coil of flat-rolled steel with a thickness as low as 1.2 mm, and of considerable length. The resulting coil produced during this process can be sold in this form to customers or further processed.

Pickling is a process in which the steel is chemically descaled by means of immersion in acid. Removal of the scale gives an improved surface finish compared to the standard `as-rolled` product and is available for all grades of material. Types available include Mill-Pickled and Oiled, Batch-Pickled with or without Oil and also Pickled material with a specialist dry film protection.

There are two different types of hot rolled steels available, Structural and Forming and each of these come in a number of different grades. Structural hot rolled steels have high tensile strength without a great weight penalty and this makes them ideal for use in construction, commercial transport, offshore structures and vessels, etc. Forming hot rolled steels tend to be highly malleable and are used for purposes which require bending, forming and drawing. Such uses include the construction of tanks and boilers, automotive components, pipework, etc.
