Aluminum Angle                                               Architectural Angle is produced with square corners and is generally used for lighter strength applications when cosmetic appearance is a concern. It is generally produced in the 6063 alloy. Normally produced in smaller, lighter thicknesses than structural angle. Structural Angle has rounded corners and is used when strength is main requirement for the application. It contains more material on the inside radius of the angle therefore giving it more strength. It is also produced in the 6061 alloy to offer greater strength than 6063. It is normally produced in larger sizes than the architectural angle.
