Cold rolled sheet is a product made by rolling hot-rolled coils at room temperature below the recrystallization temperature. Mostly used in automobile manufacturing, electrical products, etc. Cold rolling is rolling at recrystallization temperature, but generally understood as rolling materials using room temperature rolling.

Hot-rolled sheets, that is, hot-rolled steel sheets and strips, commonly known as hot-rolled sheets, are usually written as hot-rolled sheets, such as hot-rolled sheets, but they all refer to the same hot-rolled sheet. Refers to steel plates with a width greater than or equal to 600mm, a thickness of 0.35-200mm and a steel strip with a thickness of 1.2-25mm.

The equivalent material of GB/T700 Q275 carbon steel and low alloy steel plate is S275JR steel plate. S275JR steel plate is a general-purpose carbon structural steel. This steel is similar to the steels listed in China GB/T700 and GB/T1591. It is also a carbon structural steel and low alloy structural steel used in engineering steel and structural steel, which is usually not heat treated.

A572 steel has four different grades: 42, 50, 60 and 65. Each of these grades differ in their mechanical properties and chemical composition.
