Aluminum Roofing Sheet Aluminum roofing sheets are extremely light and have a high strength-to-weight ratio. Aluminum is an increasingly popular choice for use in installations and buildings. It is corrosion-resistant in almost any kind of environment. Even in highly corrosive industrial environments, it is resistant to fumes and vapours of organic compounds and to chemicals like ammonia, carbon dioxide and acids such as hydrochloric acid, nitric acid and sulphuric acid. Such corrosion resistance gives the metal a long life and keeps it looking good throughout its life. The shine and brightness of aluminum livens its surroundings, and, because it doesn't stain, discolor or rot, it keeps its brightness and shine for a long time. Aluminum corrugated sheets can take a variety of finishes, colors and textures, which protect them and further enhance their appearance. An aluminum structure can be easily dismantled, transported and re-assembled in a new location. Though the metal is a good conductor of heat, its high reflectivity for radiant heat and light (75 to 80 per cent when new, 60 per cent after several years) keeps the interiors of aluminum building from five to eight degrees Celsius cooler in summer, while its low emission rate cuts heat loss in winter.
