Hot and cold rolled steel sheet is a kind of metal material widely used in
the manufacture of electronic equipment, machine parts, automobiles, and
Cold-rolled steel is recommended for general-purpose casings. It provides a
good combination of cost and structural integrity (stiffness).
If corrosion resistance is required, consider galvanizing, stainless steel,
or aluminum. Also, consider considering the minimum weight and/or corrosion
resistance of aluminum.
Cold-rolled steel plates are made by pressing billets to the desired
thickness and shape at room temperature. It has better surface quality and
dimensional accuracy than hot-rolled steel. Cold-rolled steel plates are
commonly used to manufacture products requiring high precision and smooth

Hot-rolled steel plates are made by rolling billets at high temperatures. It
is generally cheaper than cold-rolled steel and can be used to make some
products that do not require high precision and surface quality. However, there
may be oxide skin on the surface of the hot rolled steel plate, which needs
In addition, the thickness of the steel plate is also a factor to consider.
Thick steel plates are usually used to make durable structural parts, while thin
steel plates are suitable for lightweight products.
Cold and hot rolled steel sheets can be surface treated by different
processing methods, including spraying, electroplating, and anodizing. These
finishes can improve corrosion resistance, wear resistance, and the aesthetics
of the steel plate.

In conclusion, it is very important to know the basics of hot and cold rolled
steel sheets, because they are the basic materials necessary to manufacture many
