Q355B Large Warehouse Steel Structure Fast Build, Economical, Modular Expansion
prodnct deecrlption
Large warehouse steel structure system manufactured from Q355B high-strength steel, specifically designed for modern logistics storage needs. The portal frame structure provides maximum 80-meter column-free space, meeting requirements for large rack systems and automated equipment installation. For rainy climates in Southeast Asia, efficient drainage systems and moisture barriers are designed; for high-temperature environments in the Middle East, high-reflectivity roof panels are used to reduce indoor temperatures. Modular design facilitates later expansion, allowing gradual increase of warehouse capacity according to business growth.
