Frequently Asked Questions
It is hyphenated when used as a verb (to cold-roll) or a compound adjective (cold-rolled steel). As a noun phrase, you might see 'cold rolling' (the process) or 'cold roll' informally, but the hyphenated forms are standard for the verb/adjective.
Hot-rolled steel is processed at high temperatures, making it easier to shape but with a rougher surface and less precise dimensions. Cold-rolled steel is processed at room temperature after hot-rolling, resulting in a smoother surface, sharper corners, greater strength, and more precise dimensions.
No, not all metals are suitable. The process is common for steel, aluminium, copper, and brass. The metal must have sufficient ductility at room temperature to be deformed without cracking. Very hard or brittle alloys may not be suitable.
Extremely rarely. Its primary and almost exclusive use is in metalworking. In other contexts (e.g., food), it would be interpreted literally as a cold sushi roll or similar.
