Details

Product Description
The "Cold Roof" series of color steel products are high quality color steel products produced with AkzoNobel's "Cold Chemical" coating. This product adopts heat-reflective coating to make the color-coated panels absorb visible light and reflect heat at the same time, thus keeping the room cool, reducing energy consumption during the peak of electricity consumption in summer, reducing pollution and protecting the environment. On top of ensuring excellent color permanence, high weather resistance and other characteristics, it adds an increase in excellent energy-saving performance. It meets the requirements of LEED and ENERGY STAR, and is the best solution for energy-friendly coatings.
