Architectural Aluminum
Architectural aluminum parts are used as decorative and structural components of building construction. 6063 aluminum is often the first choice because it is weather resistant, meaning it won't corrode easily, is able to withstand both high and low temperatures and won't rust when wet. Aluminum is able to last for very long periods of time without much maintenance or upkeep and provides light gauge but highly sound support. Schools, hospitals, skyscrapers, homes, offices and storefronts all use aluminum in their building construction, both internally and externally. Architectural aluminum is used to make many structural components, including window frames, railings, ceiling beams, decorative trim, window paneling, entrances, curtain wall systems, walkway covers, sunshades and doors.
Aluminum used in architectural applications is never pure aluminum, as it is much too soft. 6063 aluminum is alloyed with magnesium and iron to improve strength properties and extruded into different shapes. These shapes are often welded together and put through post-forming treatments including anodizing and coating. Anodized aluminum provides the metal with a protective surface coating of aluminum oxide by dipping it into a chemical bath. The coating will not ever peel off, as it is an actual part of the metal. PVDF coating is powder or liquid paint that provides a more temporary protective coating, as well as different surface colors and finishes to choose from. Corrugated aluminum is a popular type of ribbed sheet used in building and structural applications, usually as siding and roofing.
