Wall Structure – High-strength Corrugated Panel System
- Technical parameters: Standard container corrugated sheet (Q235B steel, 1.6–2.0mm thickness, panel width 1200mm, custom length up to 12m). Wave height 36mm, wave pitch 72mm, crest width 208mm, bending radius R5 – enhances bending and compression strength.
- Production capability: Hot-dip galvanized (Z180-Z275 coating) + RAL9005 powder coating. Excellent weather and corrosion resistance. Welding tolerance strictly controlled to ensure structural reliability.
- Dimensional match: External dimensions 11.8m×2.2m×2.5m (length close to 40ft container, height greater than standard 2.393m) – provides larger interior volume and efficient folding for transport.
Surface Coating System – High-Standard RAL9005 Finish
- RAL9005 Jet Black (RGB 10,12,16; HEX #0A0C10; LRV 0.47).
Powder or liquid coating.
- Corrosion protection: Epoxy-polyester or acrylic coating, 60-80µm dry film thickness, suitable for humid/sunny environment.
- Physical performance: Hardness up to 2H; adhesion grade 0 (cross-cut test, no detachment).
- Appearance: Matt or gloss options; dirt-hiding; good color stability.


- Interior Wall – LJ703 Panel System
Fire-retardant and eco-friendly board, providing a comfortable living/office environment, meeting visual and safety standards for export residential units.
- Flooring – Industrial PVC Cushion Mat
High-quality PVC mat, typically 2.0–3.0mm thickness. Wear-resistant, waterproof, anti-bacterial, anti-slip, noise-reducing – ideal for permanent installation on container subfloor.
- Doors & Windows – Standard Building Openings
Sliding doors: Space-saving, durable for frequent use.
Double sliding windows: Effective light and ventilation; dual windows promote cross ventilation.
For the US market, the electrical system strictly follows the National Electrical Code (NEC) and relevant industry standards.

01
External Power Inlet – US Standard Industrial Plug
Adopts NEMA L-series locking industrial receptacle (e.g., NEMA L5-20R / L5-30R, 20A/125V or 30A/125V). UL listed. Suitable for outdoor generators, RVs, trailers, or temporary construction power. Locking mechanism prevents accidental disconnection due to vibration.
02
Main Distribution Panel
Enclosure meets NEMA 3R (rainproof) or NEMA 4 (splash-proof). Three dedicated branch circuits: lighting, receptacles, and HVAC/high-power. All components (e.g., UL-listed circuit breakers) meet UL 67 testing requirements. Main grounding bar and neutral bar ensure proper electrical contact.
03
US Standard 3-Hole Receptacles (NEMA 5-15R / 5-20R)
- Configuration: Two flat pins (hot & neutral) + round grounding pin. Rated 15A–20A, 125V, 60Hz, grounding functional. Compliant with UL 498 and NEMA WD-6.
- Mounting: Flush-mount, UL 94V-0 or V-2 flame rating.
- Safety: Polarized (wide slot neutral, narrow slot hot); grounding pin at bottom/top per standard; matches US appliance plugs.
- Quantity: 10 units distributed across main areas (bedroom, living, kitchen/office) for plug-and-play of US appliances.
04
US Standard Wiring & Cables
- All conductors are copper with PVC insulation meeting US gauge standards.
- Branch circuits: At least #12 AWG (for 20A circuits) or #14 AWG (for 15A circuits). Ampacity, overcurrent protection, and voltage drop per NEC 2008/2020.
- High-power appliances (e.g., A/C) use #10 AWG or larger.
FAQ
Q: Does your company is a factory or trade company?
A: We are factory, so you will enjoy the best price and competitive price.
Q: Can you offer designing service?
A: Yes, we have own design engineers. We could design full solution drawings as per your requirements.
Q: Do you accept container loading inspection?
A: You are welcomed to send an inspector, not only for the container loading, but any time during the production time.
Q: Do you have stock for all items?
A: In general, we produce based on the order which we confirmed.
Q: Why do container house only last 25 years?
A: The service life of a container house depends on the environment in which it is placed and the degree of maintenance. If well maintained, the lifespan of a container house can reach 25 years or more. Or use shipping containers to modify them. Compared with ordinary containers, container houses converted from shipping containers use more solid materials and have a service life of at least 30 years. If they are properly stored, they can last for 40-50 years.
Q: Are container homes rust proof?
A: It can prevent rust to a certain extent, but it is still closely related to climate conditions. Therefore, we need to paint the container house several times to achieve a certain anti-rust effect.
