Aluminium is an economical alternative to stainless steel and is often specified for its light weight and strength.

Aluminium is a very good conductor of electricity and heat, it can be hammered into sheets (malleable) or pulled out into wires (ductile).

Although it is corrosion resistant, Aluminium is a highly reactive metal. Aluminium prevents corrosion by forming a small, thin layer of aluminium oxide on its surface. This layer protects the metal by preventing oxygen from reaching it, which inhibits the corrosion process.

Fabrication Methods

Aluminium can be cut, shaped and joined using:

  • TIG Welding
  • Press brake bending
  • Punching
  • Sheared and sawn


Duffys offer a range of finishes for aluminium including:

  • Painted finish (to specification)
  • Powder coating
  • Natural metal finish
  • Anodized


Aluminium is often used in the marine and automotive industry for its lightweight and heat conducting advantages.

Aluminium is used to manufacture:

  • Ladders
  • Walk-overs
  • Gantries
  • Window frames
  • Window cills
  • Flashings
  • Guttering
