Aluminium handwheel is prone to atmospheric corrosion when exposed to natural elements. Corrosion leads to surface degradation involving pitting and flaking. Flaking is particularly risky in oxygen service and may act as fuel if it comes in contact with the gas.

CED (Cathodic Electro Deposition) coating is a process of painting using electrical current to deposit the paint on the surface of a part connected to the cathode. The paint primarily consists of epoxy resin with suitable pigment for colour.
