Aluminium plate frequently asked questions:

Aluminium plates are metal plates known for their multi-functions and durability. They are used in various applications and in different industries, due to their high ductility level, which refers to how various shapes can form a curvature without breaking. On top of their ductility level, they also have a low-density level, making them lightweight.

Aluminium plate is commonly used for:

  • Transport, trailers and tippers, rail and automotive
  • Boats
  • Building systems and sun control
  • General engineering
  • Electrical boxes and housing 
  • Aquaculture and water management
  • Fixings and brackets

Aluminium plate has excellent corrosion resistance due to the formation of aluminium oxide, which adheres to the metal, eliminating the need for protective coatings.

Thickness level (also known as gauge) is the key difference between aluminium plate and sheet. Aluminium sheets are thinner in thickness than aluminium plates. Aluminium sheets range up to 5.99mm in thickness, aluminium plates have a thickness level of 6.0mm or greater.

Aluminium plates have a thickness level greater than or equal to 6.0mm. BlueScope Distribution stock Aluminium Plate products ranging from 6mm up to 50mm. We can also supply any thickness greater than 50mm through our carefully selected partner brands.

Aluminium can be as strong or soft as the project or application requires. Aluminium is available in a range of alloys and tempered to suit the application. Please ask our sales team for more information about the differences between our steel and aluminium sheet range.

Fabrication is referred to as the process in which products are created through cutting, bending and/or assembly. Here are some aluminium plate types suitable for fabrication:

  • Aluminium 3003 offers excellent corrosion-resistance, moderate strength and top-notch formability. It can undergo processes such as welding and machining across various industries including architecture, automotive and transport industries. 
  • Aluminium 5005 is the most common Australian alloy offering easy of manufacture, good corrosion resistance, simple welding solutions and the most accessible alloy in Australia. 
  • Aluminium 5052 has excellent thermal conductivity and corrosion resistance. It is widely used in the marine industry for welding and machining processes to construct fuel tanks, containers and pressure vessels.
  • Aluminium 5083 has excellent weldability and increased durability, essential for small to large vessels where high stress, minimal weight management and yield gain. It is commonly used in applications that include transport, defence, mining, agriculture, and many more.

Aluminium plates are used across various industries in Australia, requiring a variety of sheet sizes for many end-use applications. At BlueScope Distribution, we stock most standard sheet sizes (see below); and offer DNV certified products up to 2200mm wide and 11800mm in length.
