Square Tubes

Aluminium Square Tubes are easily fabricated into cubic or box structures and are an ideal component for rack building or window frames. All our Square Tubes are available in alloy grade 6063 T6, a medium strength alloy also known in the metal industry as an ‘architectural alloy’. This material has excellent corrosion resistance making it ideal for outdoor use. We supply our Aluminium Square Tubes in a standard length of 6m with the option to ‘cut-to-size’. Typical uses for Aluminium Square Tubes include:

  • Door frames
  • Furniture crafting
  • Shop fittings and stands
  • Stairs, balustrades, rails and posts
