how to clean a metal roof

The movable roof was a design that could change the structure of the top of the building. It was made up of a series of movable parts that could be opened, closed, folded, or translated according to needs. This kind of roof was used in gymnasiums, open-air theaters, exhibition centers, indoor swimming pools, and other places. Its advantage was that it could adjust the opening and closing degree according to the weather conditions and usage requirements.
