The standard layout for a 20FT unit includes two bedrooms, one living room, and one bathroom, providing a functional living space that can be further customized with specific material choices to meet aesthetic or health-related preferences.

Technical Specifications to Verify

Technical verification must focus on the structural integrity of the expandable mechanism, particularly when incorporating materials like antiseptic wood. The observed models feature a Q235 hot-dip galvanized steel main frame, which provides robust support, but buyers should confirm how wooden components are anchored to this frame. The wind resistance class is observed to be Grade 8-10, with speeds up to 110km/h, and seismic resistance is noted as Grade 8 Earthquake. It is essential to ensure that any antiseptic wood elements do not compromise these ratings, especially in terms of weight distribution and flexibility during expansion and contraction cycles.

Thermal and acoustic performance are also critical technical aspects. The observed products offer thermal insulation and sound resistance of >=30dB, which are vital for comfortable living environments. Buyers should verify the R-value of the sandwich panels and the acoustic properties of any wooden finishes to ensure they meet local building codes. Additionally, the operating temperature range of -20℃ to 50℃ and the IP65 waterproof rating indicate high durability. When integrating antiseptic wood, confirm its treatment level and resistance to moisture and pests, ensuring it maintains its integrity within the specified temperature and humidity ranges without degrading the overall performance of the unit.

Compliance and Safety Documentation

Compliance with international standards is paramount for modern expandable container houses. The observed products hold CE and ISO9001 certifications, indicating adherence to quality management and safety standards.
