Jiangsu Longze Modular Construction Co., Ltd. has been engaged in container manufacturing for over 20 years and holds international ISO 9001 and CE certifications. The frame quick splicing container is a modular building system centered on a lightweight steel frame, enabling rapid assembly through standardized connectors. Its core design philosophy is "frame-first, flexible infill," combining prefabricated frame structures with replaceable enclosure systems to achieve efficient construction, adaptable adjustments, and reusability.
Using high-strength cold-formed thin-walled steel or aluminum alloy frames as the primary support, these containers are 30%–50% lighter than traditional ones, reducing transportation and lifting costs while maintaining high load-bearing capacity (stackable up to 2–3 layers). Built as modular units, they can be freely stacked and combined. Each unit may function as an entire room, multiple rooms, or part of a larger space. Flat-pack container houses can be assembled in any length or width configuration, stacked up to three layers, and adorned with custom roofs or terraces. Thermal insulation is applied to the top and bottom frames for enhanced design efficiency. Every room is finished to standard, with all living facilities pre-installed.
