American Louver Stratus plastic perforated panels for returns & air supply in T-Grid ceilings. The Stratus all plastic panels won't corrode or fade and they're indistinguishable from metal when installed. Made of durable, engineered polymers and stainless steel screws, designed to resist rust, corrosion, yellowing or fading, and to resist mildew. The polymer itself is natively white and therefore without paint, negating the need to repaint this panel. The strong design maintains integrity and will not bend or scratch, despite being 50% lighter than its metal competitors.
