The definition of a steel louver is an architectural device that contains horizontal slats constructed of steel which are angled to admit light and air, but to keep out rain, direct sunlight, and noise. Steel louvers are a common feature in industrial and commercial buildings, as well as in residential spaces. They provide ventilation and air circulation, while also allowing natural light into the space. Steel louvers are a great way to add a touch of style to a building, as well as providing a functional purpose. When placed at the top of the wall, a steel louver can act as a protection from the elements and add an attractive architectural feature to the exterior of a building. Steel louvers are also used as a decorative feature in modern architecture, as well as in traditional designs. Depending on the size and shape of the louver, they can add a unique visual element to any structure. Overall, steel louvers are an ideal way to add both aesthetic and functional appeal to a building.
