This article provides a comprehensive guide on how to build a fruit cold store, presented by Henan Gefan Building Materials Co., Ltd., a specialist in steel structure construction. It outlines a complete four-step solution: First, it covers the collaborative design phase, emphasizing functional zoning (pre-cooling, processing, packaging, etc.) and the advantages of using a pre-engineered steel structure tailored to local environmental loads. Second, it highlights the critical role of precision steel installation, detailing the use of laser-cut components to ensure a perfect foundation for cladding. Third, it explains the construction of the thermal envelope, focusing on polyurethane/PIR panel installation, thermal bridge prevention, and multi-layer floor insulation. Finally, it discusses the integration of automated shuttle racking systems and the strategic placement of refrigeration equipment to ensure operational efficiency and long-term reliability for large-scale fruit storage.
