HRC gauge distribution - hot strip mill.

Typical gauge distribution - hot strip mill

An analysis is shown of the gauge distribution for a typical [traditional] hot strip mill producing hot rolled coil (hot band, HRC).

A coil thickness of ~2mm usually dominates, accounting for ~25-30% of strip mill output. A small proportion of thinner gauge steel is also produced, down to ~1.5mm. A typical hot rolling mill will also make thicker gauge hot rolled coil up to a thickness of ~12mm or 15mm gauge.

Plate typically starts at ~3mm but few facilities do this. A minimum plate thickness of ~4mm or even 6mm is much more common. Plate thicknesses are usually in the 3–150 mm range, with the bulk of plate volume being in the 12-35mm gauge range.
