Advantages of Hot-Rolled Steel Plate: Hot-rolled steel can effectively eliminate defects, such as grain refinement. Furthermore, bubbles and cracks generated during casting can be treated at high temperatures and then welded together, avoiding these issues.

Disadvantages of Hot-Rolled Steel Plate: After hot rolling, any non-metallic materials within the steel are compressed into thin sheets, causing delamination, which can affect quality and cause unnecessary problems.

Advantages of Cold-Rolled Steel Plate: It allows for greater deformation of the steel, raising its yield point. Furthermore, the forming speed is relatively fast, resulting in higher production yields without damaging the coating.

Disadvantages of Cold-Rolled Steel Plate: During the forming process, stresses are generated in the cross-section, causing changes in the steel's properties. Furthermore, the wall thickness of cold-rolled steel is relatively small, and subsequent processing does not increase the thickness, resulting in a reduced load-bearing capacity.
