The material used in hot rolling is steel slabs with typical dimensions of 12,000 x 1,650 x 250 mm. The slabs are heated in special ovens to up to 1,250° C and then pass through a series of rollers that gradually reduce their thickness. Finally, the slabs are moved onto a roll. Hot-rolled sheet is produced in thicknesses of approx. 1.5 to 20 mm. For better surface finish, the sheet can be pickled after cooling off. Pickling means that the sheet goes through an acid bath that removes iron oxide from the surface. Strip pickled sheet is manufactured in thicknesses of approx. 1.5 to 12 mm.

Mild steel:
Used when forming and drawing properties are more important than tensile ones.
Structural steel:
Used for general construction purposes that do not place such high requirements to plasticity. Guaranteed minimum yield and tensile strength values
High-strength micro-alloyed steel:
Combines high strength and good plasticity. The perfect steel for bending, which also provides great opportunities for weight savings.
Pressure vessel steel:
Designed for closed pressurised containers.
Weathering steel:
Develops an effective atmospheric rust protection of its own.
