Cold rolling steel is made of hot rolled coil under recrystallization temperature at room temperature. Cold rolled steel sheet is produced by cold rolling process, which is called cold plate. The thickness of A588 Gr A structural steel plate, cold rolled sheet is generally between 0.1 mm and 8.0 mm. The thickness and width of cold rolled sheet produced by most factories are less than 4.5 mm. The thickness and width of cold rolled sheet are determined according to the equipment capacity of each factory and market demand.

Low alloy high strength steel is a kind of engineering structural steel developed by adding a small amount of Mn, Si and a small amount of Nb, V, Ti, Al and other alloy elements on the basis of carbon structural steel, A588 Gr A structural steel plate. The so-called low alloy means that the total amount of alloying elements in steel is less than 3%. High strength is relative to carbon engineering structural steel. The development principle of low alloy high strength steel is to use as few alloy elements as possible to obtain as high comprehensive mechanical properties as possible, so as to meet the requirements of use and low cost.
