Industrial Aluminium highlights

Understand the system before choosing the route.

Start here when the project wants a Crittall-like frame rhythm, but aluminium is the better route for cost, lead time or performance.

Closed black steel-look aluminium doors
Frame rhythm

Strong glazing bars without the weight of full steel.

Industrial aluminium works when the frame layout is treated as part of the architecture, not an afterthought applied to a standard aperture.

  • Pane rhythm is drawn around the elevation and room layout.
  • Dark finishes create definition without crowding the glazing.
  • Aluminium can suit projects where lead time and thermal performance matter.
Black industrial aluminium internal screen detail
Internal screens

Broken-plan rooms with clear sightlines.

Internal screens and partitions can divide a space while keeping borrowed light, long views and a more architectural feel.

  • Useful between kitchens, hallways, studies and living spaces.
  • Finish and hardware should match the surrounding interior language.
  • Door direction and thresholds are confirmed before survey.

Detail

The industrial look depends on precise junctions.

Handles, interlocks, bars and surrounding finishes need to be specified together so the result feels deliberate rather than decorative.

  • Profile depth affects how strong the frame reads.
  • Hardware should feel consistent with the frame language.
  • A measured survey confirms the correct route for the project.

Industrial aluminium or genuine Crittall?

Both can be right. The useful distinction is whether the project needs genuine steel heritage or the faster, lighter aluminium route.
