Left Banner Mobile Toilet Supply

The supply of steel-structured mobile toilets in Tumote Left Banner requires special attention to materials, functional adaptability, and supplier selection, as detailed below:

I. Material and Structural Requirements

Steel-structured mobile toilets adopt a modular design, with core materials meeting the following standards:

• Base Material: The main frame is recommended to use 1.5mm galvanized steel sheet, which must pass a salt spray test of ≥500 hours to adapt to high-humidity or saline-alkali environments and prevent corrosion.
• Wall Filling: 48kg/m³ density rock wool board is used, providing both thermal insulation and fire resistance (with a combustion performance rating of Class A).
• Roofing: 0.4mm galvanized aluminum-zinc color steel sheet is selected, with a reflectivity of ≥70%, effectively reducing indoor temperatures in summer and extending material lifespan.
  Such structures can shorten the construction period by 80% and improve seismic performance by 50%, making them suitable for the geological conditions of Tumote Left Banner.

II. Functional Adaptability Design

In response to local climatic characteristics, the following functional modules need to be configured:

• Cold and Wind Resistance:
  • Pipes are equipped with an electric tracing system to prevent freezing and cracking in winter.
  • Windows and doors use double-glazed units (with a heat transfer coefficient of ≤2.5W/(㎡·K)) to reduce heat loss.
  • Triangular reinforcing bars are added at wall corners, with a wind pressure resistance of ≥1.5kN/㎡, to withstand sandstorms or strong winds.
• Sand Prevention Design: Windows and doors adopt a three-stage sealing structure, with a dust blocking rate of ≥95%, preventing sand intrusion.
• Sewage Disposal System:
  • Vacuum collection type: Consumes only 0.8L of water per use, suitable for areas with sufficient water resources.
  • Waterless bio-enzyme degradation type: Requires no flushing, suitable for water-scarce or pastoral areas.
• Energy Solutions: Optional 200W photovoltaic panels (with an average daily power supply of 2.5kW·h) or a wind-solar hybrid system can meet the power needs of areas without grid coverage.

III. Supplier Selection and Procurement Considerations

• Recommended Suppliers:
  • Inner Mongolia Sanfeng Environmental Protection Engineering: Offers processing and customization services, with materials including HDPE and galvanized steel, supporting a one-stop service of leasing, cleaning, and maintenance (Contact: Mr. Cao, 185 4782 2732).
  • Other Brands: Such as Xuhu, Changjiu Environmental Protection, and Deshun, offer products covering materials like stainless steel, color steel, and plastic, meeting diverse needs.
• Qualification Verification:
  • Require suppliers to provide the Steel Structure Engineering Construction Qualification, material SGS certification reports, and fire rating certificates (with a Class A combustion performance rating for wall materials).
• Acceptance Standards:
  • Conduct on-site inspections of weld continuity, window and door sealing, and drainage stability.
  • Require manufacturers to provide a list of wear parts (such as motors and seals) and clarify a fault response mechanism (recommended: on-site response within 4 hours).
