Aluminium sheet has a long and well-proved record of reliability and economi- cal service for a wide range of permanent building applications, In the severe industrial atmospheres and under extreme climatic conditions, notably in the tropics, aluminium has demonstrated its remarkable quali- tios of endurance by comparison with other building materials. The special properties of aluminium-notably its durability, lightness and strength-have es- tablished it as on ideal material for such building applications as roofing and siding, flashings' and weatherings, guttering, glazing bars, structural members and decorative trim.
