What Materials Are Used for Container House Floors

Common materials used for container house floors include fiber cement boards, wooden floors, magnesium oxide fireproof boards, and plastic floor coverings, with the specific choice depending on the usage scenario, functional requirements, and cost budget.

1. Fiber Cement Boards
Fiber cement boards are one of the mainstream choices for container house floors. Made from cement as the base material, reinforced with mineral fibers, and pressed under high pressure, their core advantages include:

• Fire and Moisture Resistance: Pressed by a 7000-ton press, the boards have a high density, achieving an A-grade fire rating. They are also resistant to deformation and mold in humid environments, making them suitable for construction site dormitories and temporary offices.
• Load-Bearing and Stability: Lightweight yet strong, with a surface density of 0.85–1.27g/cm³, they offer excellent impact and flexural resistance, low wet expansion, and thermal shrinkage rates, ensuring long-term durability without cracking.
• Easy Construction: They can be sawed, nailed, and painted, supporting rapid installation. Additionally, they are free from harmful substances like asbestos and formaldehyde, meeting environmental standards.

2. Wooden Floors
In traditional container transportation, wooden floors are a common choice, primarily due to the following reasons:

• Weight Reduction and Elasticity: Wood has a lower density than steel, reducing transportation weight. It also has some elasticity, allowing it to return to flatness after being crushed by heavy objects, minimizing the risk of container floor depression.
• Moisture Resistance and Fixability: Wooden floors treated with fumigation can absorb a small amount of water vapor, keeping cargo dry. When fixing pallets with nails, wooden floors offer stronger nail-holding power than steel and are easier to replace and maintain.
• Limitations: Wooden floors have a shorter service life (about 1-2 years) and are prone to moisture damage and rot, requiring regular maintenance. Therefore, they are more commonly used in transportation scenarios rather than long-term residential container houses.

3. Magnesium Oxide Fireproof Boards
For the fire safety requirements of residential containers, magnesium oxide boards are an ideal choice:

• Fire Resistance: They can withstand temperatures up to 1000–2000℃, remaining non-combustible at 800℃ and flameless at 1200℃, meeting the A1 non-combustible standard.
• Water and Mold Resistance: Unaffected by moisture and steam, they do not develop efflorescence or salt deposition over long-term use, with a lifespan of several decades.
• Lightweight and High Strength: With a low surface density, they impose minimal building load and offer excellent sound insulation and thermal insulation, suitable for scenarios with high safety requirements.

4. Plastic Floor Coverings
With the development of modular construction, PVC plastic floor coverings are becoming increasingly popular:

• Integrated Functions: They offer four-fold performance in waterproofing, moisture resistance, wear resistance, and flame retardancy, passing B1-grade fire certification and R10 slip resistance tests, meeting the needs of emergency shelters and overseas infrastructure projects.
• Aesthetics and Customization: They support customizable patterns to match different design styles and offer high installation efficiency, suitable for commercial displays and temporary shops.
