Photo of close-up of the 50-A louver

A 50-A louver system is a non-retractable slatted blind with 50-A louvers. These louvers are made from roll-formed aluminium, and have a width 50 mm. A 50-A louver system is suited for all kinds of internal installations; horizontal, vertical, and sloping. Even upside down. The 50-A louvers are generally movable, but can also be placed in a fixed position. The 50-A is available in a variety of colours, and wood-finish. There are even perforated variants.

Profile of the 50-A louver

The front, the visible side, of the 50-A louver is slightly rounded. The back of the blade is designed for optimal fixation of the slat clip that holds the blade.

A variety of Colours and Treatments

The 50-A louver is available in a selected range of colours as shown here below. In general, the 50-A louver is available from stock in these colours. The other aluminium components can be supplied in any RAL colour. It is even possible to have louvers, rack arms and plastic components in distinguishing colours to achieve sophisticated architectural impressions.

The most common treatments for aluminium parts are powder coating and anodising. Natural anodising is the quite common, though anodizing in colours is also possible. Powder coating is possible in all RAL colours. Custom made colours and structures are possible on request.
