With lightweight design and flexible disassembly as the core selling points, it is suitable for multi-scenario space renovation such as supermarket attics, office areas and small warehouses. High-quality light-section steel materials are selected, with light overall self-weight and low requirements for the bearing capacity of the original building floor, so construction can be carried out without large-scale reinforcement. The modular components support free combination and splicing, and the mezzanine area and layout can be flexibly adjusted according to the site size to meet the personalized space needs of different users. At the same time, the components can be disassembled and reused. If relocation or space layout adjustment is needed in the later period, they can be quickly disassembled and reassembled, effectively reducing the cost of secondary transformation. Its simple and beautiful structural design can also integrate with various decoration styles, combining practicality and aesthetics.
