ASTM A1008 Grade 50 Cold Rolled Steel Plate 0.30-3.5mm Thickness SPFC 590 S3550 Q345
Zhengde cold rolled steel plate is manufactured from hot-rolled steel strips through cold rolling processes to produce steel plates with thickness less than 4mm. The cold rolling at room temperature eliminates oxide scale formation, resulting in superior surface quality and precise dimensional accuracy. Annealing treatment further enhances mechanical and technological properties, making these plates suitable replacements for hot-rolled thin steel sheets in various applications, particularly in home appliance manufacturing.
