This fully assembled mezzanine racking system is designed for warehouses with a clear height of over 4.5 meters, creating two to three levels of independent storage or operational space. It accommodates forklift access on the lower level and manual picking on the upper level, and comes equipped with standard staircases and safety guardrails, effectively doubling storage capacity without the need for building expansion. Ideal for supermarket warehouses, distribution centers, and the storage of diverse, small-batch goods—such as e-commerce products, electronics, apparel, and light industrial items—it features a modular design for rapid installation, easy disassembly, and reusability, all at an affordable price.
