Xinyang Container House Materials

Container house materials in Xinyang mainly include the main structure, envelope system, flooring, roofing, doors and windows, and other auxiliary materials, as follows:

1. Main structural materials The main structure uses Q235B hot-dip galvanized square tubing, with columns sized 80×80×2.5mm. Hot-dip galvanizing forms a dense zinc layer on the surface that effectively prevents steel corrosion and extends service life. The high strength of the square tube (Q235B yield strength ≥235MPa) ensures the container house’s load-bearing capacity, resisting wind, snow, and other natural loads while meeting modular assembly requirements.

2. Envelope system materials The envelope centers on 75-100mm thick rock wool or glass wool sandwich panels, with a fire rating of Class A (non-combustible), meeting building fire codes. Thermal conductivity is ≤0.04W/(m·K); this low conductivity significantly improves thermal insulation and reduces energy use. Sandwich panels consist of two metal skins (such as color-coated steel) bonded to a rock wool/glass wool core, combining light weight with high strength for fast installation.

3. Flooring materials Floors use a multi-layer composite: 12mm cement fiberboard as the base for a flat, solid support; a moisture barrier film in the middle to block ground moisture; and a 2mm PVC floor surface that is wear-resistant and easy to clean. A galvanized steel bracket underneath elevates the floor 100mm, creating a moisture-proof cavity so ground dampness does not contact the floor directly, extending service life.

4. Roofing materials Roofs are finished with SBS waterproof membrane and 0.6mm color-coated steel sheet. The SBS membrane is hot-melt applied to form a seamless waterproof layer against rain penetration; the coated steel resists corrosion and extends roof life. Some roofs reserve PV panel mounting positions for renewable energy; rainwater collection gutters support water recycling.

5. Door and window materials Doors and windows use thermal-break aluminum alloy frames with 5+12A+5 insulating glass. The thermal break interrupts heat conduction and lowers energy use; insulating glass (two 5mm panes with a 12mm air gap) further improves sound and thermal performance, while sealing gaskets ensure airtightness and living comfort.

6. Other auxiliary materials

• Sealing and pest control: EPDM rubber seals between the floor and frame; drain holes and rodent mesh at the wall base to prevent water backup and pest intrusion.
• Corrosion protection: Extra anti-corrosion coating on the bottom of the unit against ground moisture and chemical corrosion.
• Module connections: Dedicated sealing strips and locking systems for tight module joints and overall stability.
• Feature upgrades: Some products add fresh-air systems (indoor air quality) and underfloor heating pipes (winter heating efficiency) for diverse needs.
