Compared with carbon steel, alloy steel plate is a steel plate with other alloy elements added to the material, and the material performance is more excellent. Compared with other steel plates, alloy steel plates have outstanding performance. First, A573 Grade 58 welded construction, alloy steel plate has higher strength, stronger bearing capacity, less breakage when bearing large objects, and longer service life. Second, alloy steel plate has good corrosion and wear resistance. In the open air environment, the steel selected for road and bridge paving must have high corrosion resistance and wear resistance, otherwise it will be damaged after a period of use and it will easily lead to accidents.
