324 Overhead Steel: Roof panels can cover wide areas while keeping the spaces beneath cool Industrially produced steel roof panels are robust, material-efficient, and easy to install. They feature a standing seam, which forms a waterproof connection to the next sheet and allows for the coverage of very large surfaces while creating an appealing, regular pattern. They are available in lengths up to fourteen meters and come in more than twenty standard colors. If chosen in bright white the panels have the additional benefit of reflecting sunlight, which helps keep the surface of the panel up to 24°C cooler than dark roofs.
