Normally aluminium canopies are designed to protect and cover metallic surfaces that are exposed to the environment. Surfaces that are exposed to salt spray, steam, and exposure to varying temperatures are respectively called marine coverings. Aluminium canopies are designed to provide low-impact corrosion protection to structures as substantial as an aircraft fuselage panel. They were designed initially by the British Aircraft Corporation.
When designing canopies for use in aircraft, the British Aircraft Corporation requirements called for a corrosion-resistant material that was able to offer protection against corrosion in an aircraft fuel tank or any other corrosion-prone environment. The material was also required to resist the agents that can cause corrosion. The canopies provided the integrity and protection needed for use in aircraft that were manufactured to this specific specification.
Aluminium has long been used to increase the impact resistance of concrete grades and sheet metal thickness as a base material for magazines as well. Specially treated aluminium is applied to surfaces to form a protective covering to protect against corrosion. The material provides marine coverings that are resistant to water, solvents, and solvents, oil, fuels, alkalis, and airborne particles. They offer the same corrosion resistance as stainless steel that the tough surfaces used in aircraft make it possible for them to withstand salt spray, jet fuel, oil, fuel, and acid.
