Frequently Asked Questions (FAQ) for Wholesale Buyers
Comprehensive engineering and commercial responses to common buyer inquiries regarding OEM customization, shipping logistics, and site preparation.
Our manufacturing facilities operate under strict ISO 9001 quality management systems. Primary structural steel frames are constructed using Q235B/Q355B hot-dip galvanized steel, delivering a design lifespan exceeding 25 years. Every unit undergoes rigorous factory water-spray testing (simulating torrential rain at 150mm/hr) and structural weld inspections prior to export packaging.
Units are engineered to fold into a compact standard container dimensions. A 40-foot High Cube (40HQ) ocean container can comfortably fit two folded 20-foot expandable houses or one 40-foot expandable house. All delicate fixtures, windows, and electrical components are internally secured and padded to prevent damage from dynamic ocean transit forces.
Expandable container homes require a level ground surface. Recommended foundations include concrete corner piers, strip foundations, or a full poured concrete slab. Ground screw piles are also popular for eco-resorts where earth disruption must be minimized. The perimeter frame features adjustable leveling feet to compensate for minor ground variances.
Yes. As a factory-direct manufacturer, we support extensive OEM/ODM customization. Clients can customize interior room partitions (1 to 4 bedrooms), select integrated kitchen/bathroom layouts, specify cladding materials (wood grain, stone texture, metal panels), and request destination-specific electrical wiring (US NEC, EU CE, AU/NZS 3000).
Thermal envelope performance is tuned to the project location. For cold regions (e.g., Northern Europe, Canada), we utilize 75mm to 100mm high-density Polyurethane (PU) or Rock Wool cores with broken-bridge double-glazed Low-E windows. For high-heat regions (e.g., Middle East), reflective exterior coatings and integrated HVAC ducting ensure thermal comfort and low cooling loads.
Standard production lead time for a 20-unit container batch is typically 15 to 20 business days from shop drawing sign-off. High-volume orders (100+ units) are fulfilled through dedicated automated production lines maintaining throughput capacities exceeding 5,000 units per month.
