Defects in colour coating sheets can include chalking, fading, peeling, and cracking.

• Chalking occurs when the coating breaks down and forms a powdery residue on the surface.

• Fading happens when the colour loses its vibrancy and becomes dull.

• Peeling occurs when the coating separates from the substrate, leaving patches of exposed metal.

• Cracking happens when the coating develops small cracks, which can lead to corrosion.
