Gold, copper and silver steel coating in much infrared location, the wavelength number of greater than 4 mu m, a high reflectivity. As for the typical metallic coating thickness, total reflectivity of around 90%-95%, high infrared reflectivity is reminiscent of very low emission level (Low-e), this would reduce the radiation https://brooksnnlig.thezenweb.com/top-latest-five-special-cement-concrete-urban-news-73677884
