Why do the construction companies provide more demand for aluminium ?
Answers
Explanation:
As the extraction process is relatively expensive, aluminium was generally not used in construction until the early-20th century. In the 1920s, it began to be used primarily for decorative detailing and Art Deco structures. In the 1930s, a breakthrough was achieved when the Empire State Building used aluminium for much of its interior structures and its famous spire. Subsequently, it began to be used for roofing, flashing, wall panels, spandrels, and so on.
Today, aluminium is the second most used metal in buildings after steel.
Because of its ductility, aluminium can be formed into many shapes and profiles. Aluminium wall cladding systems are commonly used for building exteriors, with large wall panels requiring fewer joints, resulting in time-efficient installation.
Some of the most common applications for aluminium are:
Long-span roof systems covering large areas such as halls and auditoriums.
Structures located in inaccessible places where the economy of transport and ease of installation are important, such as electrical transmission towers.
Structures in corrosive or humid environments, such as swimming pools, bridges, hydraulic structures, offshore superstructures, and so on.
Structures with moving sections, such as moving bridges.
Structures to which access for maintenance is limited, such as masts, lighting towers, antenna towers, and so on.
