The black brick is a fusion innovation of modern photovoltaic science and technology and building masonry culture. The product can be used as a new type of building exterior wall decoration material. It is corrosion-resistant, non-fading, easy to clean, light in weight, hook-mounted installation, and avoids traditional stone on-site cutting and polishing. The technology has no dust pollution and saves materials. Blue bricks provide a new choice for green building energy saving.
