cold rolled sheet

The products details 1 Definition: it is formed by rolling hot-rolled plate coils (raw materials) at normal temperature and then at recrystallization temperature. Cold-rolled steel plate is produced by a cold rolling process, and is called cold plate for short.

The thickness of cold-rolled plates is generally 0.1-8.0mm; the thickness of cold-rolled steel plates produced by most factories is less than 4.5mm; the thickness and width of cold-rolled plates are determined by equipment capacities of various factories and market demands.
