Venetian Blinds are multiple strips of around 25mm (1 inch) from top to bottom. The strips of venetian blinds are normally made of colour coated aluminium strips. All strips are attached to one another by the wave of the blind running from top to bottom.
The blind can be turned to around 170 degree. You can keep the blinds fully open, partially open or fully closed. The blinds can also be accumulated on the top with the control channel if you want fully open view.
