Typical Hot Strip Mill Gauges
An analysis is shown of the 2024 gauge distribution for a typical [traditional] European hot strip mill producing hot-rolled coil (hot band, HRC).
A coil thickness of about 2 mm usually dominates, accounting for about 25–30% of strip mill output. A small proportion of thinner gauge steel is also produced, down to about 1.5 mm. A typical hot rolling mill will also make thicker gauge hot-rolled coil up to a thickness of about 12 mm or 15 mm gauge.
Plate typically starts at about 3 mm but few facilities do this. A minimum plate thickness of about 4 mm or even 6 mm is much more common. Plate thicknesses are usually in the 3–150 mm range, with the bulk of plate volume being in the 12–35 mm gauge range.
