DeltaBox Cladding And Screening


DeltaBox is a steel louvred panel system, offering durability and an aesthetic design. It is manufactured with a range of options, offering a choice of total or partial visual screening with a corresponding level of free area for ventilation.

The steel construction creates a robust panel suitable for ground and street-front locations as well as roof-top and elevated situations.

Framed panels are made to custom-sizes for a wide variety of applications such as wall cladding, car park screens, compounds, plant housing, ventilation grilles, balconies and balustrades, wheelie bin stores and brise soleil.

DeltaBox is manufactured from inclined carbon steel flat bars, which are pressure locked to in-line vertical flat bars.

The inclined louvres can be spaced at any increment of 11 mm to provide the required level of visual screening.

  • Louvre flat bars 40 x 2 mm set at 45 degrees, centred at 22, 33, 44, or 66 mm.
  • Vertical flat bars 20 x 2 mm, centred at 132 mm.

Panels and ancillary steelwork can be supplied galvanized only or galvanized and powder coated to any RAL colour.
