amplibeam Aluminium Beams

AMPLIBEAMS - Expanded aluminium beams

AMPLIBEAMS are aluminium beams manufactured using the AMPLIFORM process. This unique process makes use of an aluminium alloy extrusion that firstly has slots punched in preset positions using a purpose made machine and then stretched to a predetermined width.

There are 3 standard AMPLIBEAMS –

  • ALB 200 – 200mm deep x 50mm wide up to 6m long
  • ALB 365 – 365mm deep x 50mm wide up to 6m long
  • ALB 475 – 475mm deep x 75mm wide up to 6m long

Amplibeams are manufactured for Aluminium Alloy 6063 Condition T6.

For more information and design assistance please do not hesitate to contact us.

Amplibeam expanded beams have found applications in a wide variety of structural aluminium applications. These have included roofing structures and stringers in bridges etc. The light weigh and corrosion resistance of the aluminium makes them perfect for corrosive and inaccessible areas.

The various uses and benefits of the AMPLIBEAM


Amplibeams are manufactured in 3 different sizes  ALB 475 ,  ALB 365 and  ALB 200.

It is common to join the beams using a 4 way H connector. This ensures a stiff, compact joint. The 4 way H Connector may be cut back to a 3 way or 2 way connector.

Amplibeams are manufactured using Aluminium Alloy 6063 in condition T6. Aluminium alloy 6063 is a heat treatable, wrought alloy.

Aluminium alloy 6063


AMPLIBEAMS are very versatile structural elements. No other metal product has a better strength to weight ratio.


  • are light weight
  • corrosion resistant
  • easy to fabricate
  • can be anodised or powder coated.

AMPLIBEAMS can be joined by welding, bolting, riveting or any other method provided suitable design criteria are applied.

We offer a range of AMPLIBEAMS and bolted 4 and 2 way H connectors that are suitable for various applications.

AMPLIBEAMS have found their way into a wide variety of applications.
