Overview
Executive summary

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.
