Lightweight, corrosion-resistant hollow extrusions available in structural (6061-T6) and architectural (6063-T6) grades, offering excellent strength-to-weight ratios and 95% recyclability for sustainable construction applications
Aluminium tubes are precision-extruded hollow sections manufactured from high-grade aluminium alloys, primarily 6061-T6 for structural applications and 6063-T6 for architectural uses. These tubes comply with AS/NZS 1866:1997 standards and offer exceptional corrosion resistance, particularly in Australian marine and coastal environments. Available in diameters from 6mm to 300mm with wall thicknesses from 1mm to 25mm, they provide versatile solutions for frameworks, handrails, structural supports, and architectural features. The material's inherent properties include excellent thermal conductivity, non-combustibility for bushfire compliance, and infinite recyclability with minimal energy input.
