Fixed louvered grille (FLG)

The fixed louver grille is a type of grille that consists of slanted slats (louvers) that are fixed in a frame. These slats are positioned at a specific angle, allowing the passage of air and light while simultaneously preventing the direct entry of water, dust, or direct sunlight. They are typically painted in RAL 9010 but can be coated in any RAL color. An additional insect screen can be attached to the grille.

These grilles are often used in ventilation, heating, or air conditioning systems, as well as for decorative purposes or to protect certain areas from weather conditions. Fixed louver grilles are made from aluminum profiles, which eliminates the possibility of rust forming on them.
