Fengkai Container House Maintenance

The maintenance of container houses in Fengkai requires special attention to the warranty scope, routine maintenance, usage specifications, and protective measures, as detailed below:

1. Clarify the warranty scope and responsibility boundaries
The warranty for container houses typically covers three aspects: structure, enclosure, and utilities, with specifics determined by the contract. The warranty period for structural components (such as the main frame and C-shaped steel welds) is generally 1-3 years; for enclosure components (such as color-coated steel sheets, doors, windows, and sealing strips), it is 6-12 months. However, deformation caused by human impact, unauthorized drilling, overloading, or failure to reinforce after typhoons, as well as normal rusting and paint wear, are not covered under warranty. It is recommended to take photos of the warranty scope upon receipt to avoid misunderstandings that may lead to self-funded repairs.

2. Perform routine maintenance regularly

• Monthly inspection: Clear leaves from the roof and gutters to prevent blockages that can cause water accumulation and rust.
• Quarterly maintenance: Check the sealing strips on doors and windows for aging and replace them promptly to prevent air and water leaks.
• Semi-annual repainting: Apply anti-rust paint to welds and bottom beams to slow down steel structure corrosion.
• Annual tightening: Inspect and tighten bolts, and have a professional electrician check electrical connections to prevent safety hazards caused by loosening.
  In Guangxi, where humidity is high and the rainy season is long, it is essential to strengthen drainage and rust prevention measures to avoid minor issues escalating into major repairs.

3. Standardize usage behavior

• Prohibit unauthorized modifications: Do not alter the original design functions, overload, or remove structural components (such as bolts and steel frame fittings) to avoid compromising structural stability.
• Fire, corrosion, and water prevention:
  • Avoid welding near walls and keep fire sources at least 50 cm away from walls;
  • Regularly inspect the drainage systems in bathrooms and shower rooms to prevent water accumulation and corrosion;
  • Although rock wool fire-resistant containers have strong fire performance, it is still necessary to install range hoods and other equipment to reduce open flame risks.
• Chemical corrosion prevention: Avoid exposing containers to acids, alkalis, salts, and other chemicals. If accidental contact occurs, rinse immediately with clean water.

4. Long-term storage and transportation protection

• When not in use: Provide shade and rain protection to prevent paint aging from direct sunlight and corrosion from rainwater.
• During transportation: Avoid obstacles to prevent scratches on the protective surface layer, which can reduce the overall service life.
