Linzhi Customized Mobile Toilet

The Linzhi customized mobile toilet is a modular public sanitation facility specifically designed for special environments characterized by high altitudes, frequent rain and snow, and significant temperature variations. It must meet core requirements such as corrosion resistance, thermal insulation, slip resistance, and electrical compatibility, while also complying with national standards and local service requirements.

I. Core Design Requirements

1. Environmental Adaptability

   • Corrosion Resistance: The main frame is made of Q235B or higher hot-dip galvanized steel, with a surface spray-coating thickness of ≥80μm (e.g., double-layer process of galvanizing + spraying), to withstand the humid and rainy environment in Linzhi.
   • Thermal Insulation: It supports stable operation from -20℃ to 40℃, with a built-in heating strip in the water tank (temperature controlled at 5℃ ± 2℃), and anti-freezing ceramic valve cores in the squatting/sitting positions to prevent freezing at low temperatures.
   • Slip Resistance: The ramps and floors are equipped with emery slip-resistant layers to reduce the risk of use during rainy and snowy weather.

2. Power Supply

   • It supports dual-mode power supply from the mains grid/solar energy, with the solar module typically configured with a 200W photovoltaic panel + 120Ah lithium battery, suitable for the significant power fluctuations in Linzhi.

3. Functional Integrity

   • It is equipped with a complete water supply and drainage, ventilation, lighting, and intelligent management system. It is not a simple container modification but must comply with GB/T 18045-2021 General Technical Conditions for Mobile Public Toilets.

II. Key Selection Criteria

1. Material Weather Resistance: The main frame must be made of Q235B hot-dip galvanized steel, with a qualified spray-coating thickness to ensure long-term outdoor use without corrosion.
2. Plateau Adaptability: Designs such as water tank heating and anti-freezing valve cores must pass actual low-temperature tests, with a winter pipeline freezing rate lower than the industry average.
3. Compliance Certification: It must provide Sanitary Ware Freeze-Thaw Resistance Test Reports and Electrical Safety Test Reports issued by provincial-level or higher quality inspection institutions.
4. Localization Services: Suppliers must have service outlets in the seven counties and one district of Linzhi or a 48-hour emergency response mechanism to ensure efficient post-maintenance.

III. Mainstream Suppliers and Product Features

1. Guting Metal Products

   • Specializing in the Tibetan market for nearly 8 years, it provides integrated solutions (including sinks, barrier-free ramps, and solar power supply), with a daily average capacity of 120 person-times per toilet.
   • In 2025, it will undertake the construction of 12 standardized toilets along the G318, with a winter pipeline freezing rate 37% lower than the industry average.

2. Jinmuhe Metal Products Co., Ltd.

   • It is equipped with a standard biological degradation treatment system (daily treatment capacity of 30L, COD removal rate ≥ 85%), suitable for ecologically sensitive areas.
   • It supports whole-toilet hoisting and transportation, providing composite bathrooms with shower functions (including thermostatic mixing valves and PVC antibacterial wall panels).

3. Jiexin Integrated Bathrooms (Linzhi Branch)

   • It supplies single-unit public toilets made of metal carved panels, which can be customized and processed, covering Linzhi and surrounding areas.
