Hot-rolled steel coils have a rougher surface finish due to the scaling that occurs during the heating process. They typically have an oxide layer or mill scale on the surface, which may require additional surface treatments.
Hot-rolled steel coils have lower strength and hardness compared to cold-rolled steel. They are generally more ductile and have a higher tolerance for deformation.
Specification
Thickness
1.2 mm to 20 mm
Width
600 mm to 2180 mm
Hot-rolled steel coils are produced by heating the steel above its recrystallization temperature and passing it through rollers at high temperatures. This process allows for quick shaping and forming of the steel, resulting in larger thicknesses and a scaled surface finish.
