Hengzhou Iron Mobile Toilet

Although there are no direct cases of iron mobile toilets in Hengzhou, construction and selection suggestions can be provided based on the general characteristics of iron mobile toilets. Iron mobile toilets have the advantages of low cost and short construction period, making them suitable for temporary or long-term public facility scenarios. Their core design should focus on rust prevention, drainage, and structural stability.

I. Material Selection and Structural Requirements

1. Main Materials: Preferably use galvanized corrugated iron sheets with a recommended thickness of 0.4-0.6mm and a galvanized layer weight of no less than 120 grams per square meter to enhance corrosion resistance. Angle steel frames serve as the structural support, with approximately 3 kilograms of steel used per square meter, ensuring firm welding. Composite panels can be used for interior walls or partitions, balancing lightweight and durability.
2. Rust Prevention: All metal components should undergo surface sandblasting before being painted with anti-rust paint. Seams should be sealed with sealant or welding to prevent rainwater infiltration and rusting.
3. Structural Stability: The spacing between steel frames should be controlled within 60-80 centimeters. Door frames, windows, and other openings should be reinforced to prevent deformation from long-term use.

II. Key Construction Steps

1. Foundation Treatment: Choose a site away from low-lying areas. Excavate the foundation 20-30 centimeters deep, fill with crushed stone, and compact. Create a 2%-3% slope on the concrete floor and pre-install drainage pipes. Install waterproof strips (such as rubber or asphalt) at the connection between the floor and walls.
2. Panel Installation: Install panels from bottom to top, securing seams with rivets and filling with sealant. Reserve ventilation openings at the top of interior walls. Cover the roof with waterproof membranes or color-coated steel sheets, with a slope of no less than 5% for drainage.
3. Functional Optimization: The exterior walls can be painted with reflective coatings to reduce heat absorption. Install insect-proof screens and exhaust fans inside. Choose corrosion-resistant materials for door locks and lay anti-slip tiles or plastic flooring on the ground.

III. Cost and Procurement Suggestions
Market prices vary significantly depending on specifications, ranging from approximately 200-500 yuan per square meter (including foundation construction) to 3000-10000 yuan per unit (including transportation and installation). When procuring, clarify the following:

• Thickness of the galvanized layer and anti-corrosion process;
• Whether the drainage system includes a septic tank or is directly connected to the municipal sewer network;
• Whether internal sanitary fixtures (such as squat toilets, sinks) and ventilation equipment are included.

IV. Maintenance Considerations
Regularly inspect metal components for rust and apply anti-rust paint every 2-3 years. Clean drainage pipes to prevent blockages. Drain water pipes in winter to prevent freezing and cracking. If used in subtropical areas like Hengzhou, enhance ventilation design to cope with humid environments.
