Aluminum

Aluminium (the Commonwealth and preferred IUPAC name) or aluminum (North American English) is a chemical element; it has symbol Al and atomic number 13.

Aluminum is the most abundant metallic element in Earth’s crust and the most widely used nonferrous metal.

The top of the Transamerica Pyramid is covered with aluminum panels.

High-tech architecture makes extensive use of aluminium, steel, glass, and to a lesser extent concrete (the technology for which had developed earlier), as these materials were becoming more advanced and available in a wider variety of forms at the time the style was developing, generally, advancements in a trend towards lightness of weight.

Building styles resembled those of the Ashanti, including construction from earth, wood, palm oil and straw bolstered by timber frameworks and roofed with thatched leaves and wood, or later aluminum and corrugated iron.

Leopold (1902-1907) and especially the Austrian Postal Savings Bank (1903-1906, extended at 1910-12), had straight lines and geometric forms, a striking use of new materials, such reinforced concrete and aluminum, and a minimum of decoration on the facade or inside.

The facade is made of anodized aluminum and black glass.

The facade system of glass and aluminum panels installed into an inclined movement-resisting lattice contributes to overall lateral rigidity by tying back to the mega-columns with one-story high trusses at every eighth floor.

The exterior curtain wall is made of glass, stainless steel, aluminum, and granite and is criss-crossed by complex latticework cladding made of aluminum alloy pipes.

The facade for the upper stories is mostly a curtain wall made of aluminum and glass.

The buildings at the Getty Center are made from concrete and steel with either travertine or aluminium cladding.

It is a high-tech architecture structure, with use of exposed steel, aluminium panels and glass.

It consists of eight groups of four aluminium-clad steel columns which ascend from the foundations up through the core structure, and five levels of triangular suspension trusses which are locked into these masts.

The tension in the movement and free form are expressed by the gradual twisting of the aluminium-clad ribbons as they move around the building.

Their structural engineers realised the "floating dome" from 7,850 aluminium stars of varying sizes, which tessellate over eight layers to create a perforated roof structure that allows sunlight through to the spaces below.

They ended up using aluminium sheeting to replace the concrete on the outside walls because the concrete had left cracks.
