Description

Aluminium angles are extruded structural profiles featuring two perpendicular legs forming an L-shape, manufactured primarily from 6000-series aluminium alloys. These profiles combine lightweight properties (2.7 g/cm³) with excellent strength characteristics, offering tensile strengths ranging from 190-310 MPa depending on alloy and temper. Available in equal and unequal leg configurations with thicknesses from 1.5mm to 12mm, they provide versatile solutions for framing, brackets, trim, and structural support across residential, commercial, and industrial applications throughout Australia's diverse climate zones.

Aluminium angle profiles emerged in Australian construction during the 1950s with the establishment of domestic smelting capacity at Bell Bay (1955) and subsequent facilities. The introduction of curtain wall systems in the 1960s drove widespread adoption, with AS1664 aluminium design standard published in 1975 based on American standards. The 1980s saw rapid growth in architectural applications with companies like HHRobertson (later Cupples) pioneering high-rise façade systems. Modern sustainability focus has positioned aluminium as a circular economy exemplar, with Australian smelters increasingly powered by renewable energy and achieving world-leading low-carbon production metrics. Contemporary applications span from residential window frames to complex structural systems, with ongoing innovation in thermal break technology and surface treatments addressing performance requirements across Australia's diverse climate zones.
