Materials Needed for Container Houses

The materials required for container houses mainly include five categories: structural steel, wall and roofing materials, flooring materials, door and window materials, and auxiliary materials. Details are as follows:

1. Structural Steel
The core supporting structure of container houses typically uses hot-dip galvanized cold-formed steel sections (such as angle steel, channel steel, and tubing), which offer strong rust and corrosion resistance, extending the lifespan of the house. Some houses use welded weathering steel (compliant with GB/T 4171 standards) or ordinary steel (such as Q235B and Q345B), ensuring the steel strength meets load-bearing requirements. For example, the container base is often formed by welding multiple channel steels to create a stable frame.

2. Wall and Roofing Materials

• Sandwich Panels: Popular choices include rock wool sandwich panels (Class A fire-rated, soundproof, and thermally insulating), glass wool sandwich panels, or polyurethane sandwich panels (excellent thermal insulation). Rock wool panels, due to their superior fire resistance, are priced more than 50% higher than foam panels.
• Metal Panels: Such as color-coated steel sheets and aluminum alloy panels, used for exterior wall decoration, offering both corrosion resistance and aesthetic appeal.
• Other Materials: Calcium silicate boards and cement fiber boards can be used for interior walls or ceilings, providing fire and moisture resistance.

3. Flooring Materials
Common choices include cement fiber boards (wear-resistant and moisture-resistant), steel-wood composite floors, or moisture-resistant wood-grain panels. Some houses may use PVC flooring or tiles to enhance comfort. For example, detachable mobile houses often use moisture-resistant wood-grain panels, which are not cold to the touch when barefoot.

4. Door and Window Materials

• Aluminum Alloy Doors and Windows: Lightweight and corrosion-resistant, paired with insulated glass to enhance thermal insulation.
• Special Doors and Windows: Such as fire doors, security doors, or skylights, selected based on functional requirements. For example, security guard booths may use bulletproof glass or metal security screens.

5. Auxiliary Materials

• Thermal Insulation Materials: Polyurethane foam, EPS (to be avoided in crowded places), etc., used to fill gaps in walls or roofs to improve energy efficiency.
• Waterproofing Materials: Waterproof coatings or membranes applied to roofs to prevent leakage.
• Connectors: Bolts, rivets, etc., used to secure steel structures, and corner fittings (specialized container accessories) for stacking and load transfer between modules.
• Decorative Materials: Such as calcium silicate board ceilings and wooden veneer panels, used to enhance interior aesthetics.

Notes on Material Selection:

• For long-term use scenarios (such as homestays and elderly care residences), it is recommended to prioritize light steel keel structures with rock wool sandwich panels for superior fire resistance and durability.
• Houses that are frequently moved need to ensure materials are lightweight and securely connected to avoid damage during transportation.
• Strictly adhere to fire safety regulations, prohibiting the use of EPS and other flammable core materials in crowded places, with a fire resistance limit of the enclosure structure of ≥0.5 hours.
