The main difference lies in the angle of projection and functionality. Drop-arm awnings, such as the METRO, offer a variable projection angle between 0° and 170° (up to 150° on some models), making them ideal for variable sun protection without restricting the view outside. Projecting awnings, such as the VISOMBRA, allow a projection angle of up to 180° and are ideal for precisely matching light and shade to create a warm and pleasant atmosphere.
