Boards Used for Mobile Toilets in Fujian
The commonly used boards for mobile toilets in Fujian include color-coated steel sheets, wood-grain-finished metal sheets (mostly metal carved sheets), and FRP (fiberglass reinforced plastic). Different boards have distinct characteristics in terms of structure, performance, and applicable scenarios.
Color-coated steel sheets are one of the most widely used boards in mobile toilets in Fujian. Their structure consists of a color-coated steel sheet combined with a core material such as foam or rock wool. The coated steel sheet provides rust resistance, weather resistance, and decorative functions, while the core material imparts thermal insulation and sound insulation properties. For example, foam core materials are lightweight and cost-effective, suitable for scenarios with low thermal insulation requirements; rock wool core materials have a high fire rating and are often used in public places with strict safety requirements. The advantages of color-coated steel sheets lie in their easy processing, controllable costs, and rich surface colors, which can meet diverse design needs through different coating colors.
Wood-grain-finished metal sheets (metal carved sheets) are mostly used for the exterior decoration of mobile toilets. Their core material is a metal substrate (such as galvanized steel sheet), with a wood-grain texture formed on the surface through thermal transfer printing or film-laminating processes. These sheets combine the strength of metal with the natural beauty of wood grain, featuring a simple and modern style that is dirt-resistant and easy to clean. For example, a design with dark gray three-dimensional vertical grilles paired with wood-grain finishes can both hide dust and enhance the building's three-dimensional sense through linear elements. Additionally, metal carved sheets can be filled with thermal insulation materials inside to further enhance their thermal insulation performance, making them suitable for the climate conditions in Fujian with significant temperature variations.
FRP (fiberglass reinforced plastic) is another important material, composed of glass fibers and synthetic resins (such as unsaturated polyester resins). Its core characteristics are lightweight and high strength, with a density only one-fourth that of steel but a tensile strength more than twice that of steel, making it suitable for mobile toilet structures that require weight reduction. At the same time, FRP has excellent corrosion resistance, capable of withstanding environmental erosion from acid rain and salt spray, and strong aging resistance, remaining resistant to deformation or cracking during long-term outdoor use. For example, in the coastal areas of Fujian with high humidity and heavy salt content, FRP sheets can effectively avoid the rusting problems of traditional metal materials and extend the service life of the facilities.
In practical applications, mobile toilets in Fujian often adopt a combination of multiple boards: wood-grain-finished metal sheets are used for the exterior to enhance aesthetics, color-coated steel sheets are used for internal partitions or walls to balance cost and functionality, and FRP is selected for roofs or special structural parts to enhance durability. This combined design not only meets the practical needs of public facilities but also adapts to the climate and usage scenarios in Fujian.
