Gansu Color Steel Plate Mobile Toilet

The Gansu color steel plate mobile toilet is a mobile sanitary facility based on modular construction technology, combined with weather-resistant materials and an environmentally friendly treatment system, suitable for the climate conditions in northwest China. Its characteristics can be elaborated from the following aspects:

1. Modular Design and Efficient Production
Modular construction technology is employed to break down the toilet into independent units such as the frame structure, sanitation system, ventilation module, and sewage treatment components. All units are prefabricated in the factory and connected through standardized interfaces, reducing on-site construction time and minimizing environmental impact. Taking Qinghai Shiquan Color Steel Factory as an example, the production process includes raw material warehousing, steel plate leveling and shearing, stamping and forming, carbon dioxide arc welding, and spraying treatment. The coating thickness is controlled between 80 and 120 micrometers, forming a complete anti-corrosion system. The production equipment is gradually becoming numerically controlled, and the application of laser cutting machines and automatic welding robotic arms has improved processing accuracy.

2. Weather-Resistant Materials and Structural Optimization
The covering material is galvanized aluminum-zinc steel plate, with an aluminum-zinc alloy layer formed on the surface through a hot-dip process, creating a dense protective film. This can resist strong ultraviolet radiation and temperature variations in northwest China, with a corrosion-resistant lifespan 2 to 3 times that of ordinary materials. The internal structure uses light steel keels, which ensure strength while controlling transportation weight, adapting to the windy and sandy environment and low winter temperatures in Gansu. The composite insulated wall structure uses 100-millimeter-thick rock wool sandwich panels with a thermal conductivity coefficient lower than 0.038 watts per meter-kelvin. The adjustable ventilation ridge on the roof can reduce the indoor temperature by 3 to 5 degrees Celsius in summer and create an indoor-outdoor temperature difference of up to 15 degrees Celsius when closed in winter.

3. Environmentally Friendly Sewage Treatment System
The sewage treatment system includes three methods: biological degradation, physical separation, and chemical treatment. The biological degradation system decomposes organic matter by cultivating specific microbial communities; the physical separation system achieves solid-liquid separation using centrifugal force and filter membranes; the chemical treatment system neutralizes harmful components with chemicals. In terms of technological upgrades, the water-saving device has evolved from a direct-flush system to a vacuum negative-pressure system, reducing the water consumption per flush to below 0.8 liters. The solar power supply system generates an average of 1.2 kilowatt-hours of electricity per day, supporting off-grid operation. Excrement is converted into soil conditioner through high-temperature composting technology. The configuration of the vacuum negative-pressure and biofilm reaction units reduces water consumption to only 10% of that of traditional toilets, saving approximately 200 cubic meters of water per toilet per year.

4. Convenient Installation and Transportation Optimization
A modular snap-fit and high-strength bolt combination system is used, with connection nodes analyzed through finite element simulation to ensure that the displacement does not exceed 1/300 of the height under a 7-level wind force. The installation process does not require on-site welding, and millimeter-level precision docking is achieved through dedicated positioning fixtures, reducing wet work procedures by about 80% and controlling the installation period within 6 working days. The outer dimensions of the functional modules are strictly controlled within the specifications of international standard containers (2.4 meters wide × 2.4 meters high × 6 meters long), allowing transportation on secondary road networks without special transit permits. The conversion time from equipment placement to operation is shortened to within 4 hours.

5. Pricing and Customization Services
Prices vary depending on specifications and purchase quantities. For example, products from Gansu Chuangxinyuan Environmental Protection Equipment Co., Ltd. start at 1,500 yuan and support customization according to needs. For the Jiuzhuo outdoor color steel plate toilets for rural sanitation in Longnan, Gansu, the price is 590 yuan when the order quantity is ≥ 1,040 units.
