The difference between hot-rolled and cold-rolled plates is as follows:


Hot rolled steel plate is divided into structural steel, low carbon steel, welded cylinder steel, and then according to various steel to find the steel you need, in order to find the density and composition of specific steel.


Hot rolled steel plate has low hardness, easy processing and good ductility.


Cold rolled sheet has high hardness and relative strength.
