For multi story industrial plants, in addition to the roof, the exterior walls can also be flexibly arranged with color steel plates, which can beautify the appearance of the building by changing the color and shape of the color steel plates. For industrial buildings with constant temperature and humidity, Shandong colored steel plates use colored steel plates with better thermal performance than brick walls as enclosure materials, which can greatly save operating costs after completion. Color steel sheets are used for public buildings: Color steel sheets are mainly used for the roofs and exterior walls of public buildings with large space requirements. Public buildings have a series of higher requirements than industrial buildings, such as providing more space, indoor air conditioning, fire prevention, etc. At present, most of these buildings use grid or pipe truss roof trusses. Therefore, the structural form imposes higher requirements on roof panel materials in terms of lightweight, thermal insulation, fire safety, waterproofing, sound absorption, durability, and other aspects. Colored steel plates are widely used in combination houses: Combination houses constructed with colored steel plates are widely used, with a series of advantages such as light overall weight, flexible combination, convenient and fast construction, no need for secondary decoration, easy disassembly and assembly, and easy demolition. Due to the shortage of urban land, many units and individuals hope to build a one story house on the roof without having to bear too much burden on the original building. This not only expands the usable area, but also solves the insulation and waterproofing problems of the original roof. The advantages of color steel composite material houses perfectly meet the needs of users. The characteristic of multiple relocations for color steel plate combination houses has also made them widely used in temporary construction. In addition, color steel plates are widely used in multifunctional composite buildings in industrial plants.
