Product Description
how is the detachable container house look like
For construction site offices, the prefabricated duplex container building offers a practical and durable solution. The galvanized steel frame, with its powder coating, provides extra anti-rust quality, ensuring longevity even in harsh outdoor environments. The main frame thickness of 2-3mm adds to the structural strength, making it suitable for demanding site conditions. This type of container house is designed for easy handling, as it can be fully disassembled into manageable sections and reassembled without the need for a crane, which simplifies logistics and reduces installation time.
When configuring your site office, consider integrating a prefab washroom unit. These container houses can be customized to include bathroom facilities, ensuring that workers have convenient access to sanitary amenities. The wall panels are available in EPS, glass wool, or rock wool, with thickness options of 50, 75, or 100mm, allowing you to choose the level of insulation and soundproofing that best suits your project. The roof panel comes with 75mm glass wool insulation, which helps maintain a comfortable interior temperature.
For medical or emergency applications, a hospital prefab house can be configured from these modular units. The structure is engineered to withstand an 8-magnitude earthquake, providing a safe environment for patients and staff. The steel security door and sliding windows enhance security and ventilation. With the ability to stack units up to 2-3 levels, you can create multi-story medical facilities or expand horizontally to accommodate more beds or treatment rooms. The cement fiber board or MGO board floor, with optional PVC flooring, offers a durable and easy-to-clean surface, essential for healthcare settings.
For remote sites or temporary facilities, a portable prefab toilet is an essential component. These container houses can be equipped with plumbing and sanitation fixtures, providing a hygienic and private restroom solution. The flat-pack design allows for efficient shipping, with 6 units fitting in a 20-foot container and 15 units in a 40-foot high cube container, reducing transportation costs. The units are also stackable, making them ideal for multi-level site accommodations where restroom facilities are needed on each floor.
With over 5000 successful projects in more than 50 countries, including Australia, the USA, Germany, France, and Brazil, these prefabricated duplex container buildings have proven their reliability and versatility. Whether you need a site office, a medical facility, or a portable restroom, the modular design allows for customization to meet your specific requirements. The competitive pricing, combined with the durability and ease of installation, makes this an attractive option for international buyers.
