Overview
Executive summary

Aluminium flat bar is a solid extruded product with rectangular cross-section, manufactured to AS/NZS 1866:1997 standards. Common architectural alloys include 6061-T6 (high strength), 6063-T5 (architectural grade), and 6082-T6 (structural grade). The material combines lightweight properties with excellent corrosion resistance, making it ideal for Australian construction environments from marine to inland applications.
