China [CN] 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.
2 Another name: steel sheet,steel plate,steel coil,cold rolled steel sheet or coil
3 Materials: Q235, Q345B, etc.
4 Surface: normal surface,bare,checkered,antiskid,galvanized
5 Technique: cold rolled
6 Specifications: 1.5m width or as the clients’ requests.
