Internal Steel Doors & Room Dividers

Internal steel doors divide spaces without blocking natural light. Used across kitchens, hallways, home offices and open-plan layouts, steel and glass room dividers create separation whilst keeping the home feeling open, bright and connected. Fluted and reeded glazing options also provide additional privacy without making spaces feel enclosed.

What is Fluted Glass?

Fluted glass is a textured architectural glass defined by a series of vertical linear grooves pressed into the surface during manufacture. These channels refract light as it passes through the pane, softening avisibility whilst maintaining brightness.

Unlike clear glazing, fluted glass offers privacy without reducing natural light. Shapes and movement remain visible, but sharp detail is obscured, creating a finish that feels both practical and architectural.

The depth and spacing of the fluting vary between products. Fine profiles create a more subtle texture, whilst deeper fluting produces greater distortion and a stronger material presence.

Steel vs Aluminium

Steel offers a level of strength and refinement that aluminium cannot replicate. Its structural integrity allows for exceptionally slim sightlines, with premium steel systems achieving visible frame widths as narrow as 20–25mm.

Aluminium is lightweight and corrosion resistant, but aluminium systems require wider profiles, often around 50mm. Resulting in a heavier appearance that lacks the precision and character of genuine steel glazing.
