  • The Prefab Steel Warehouse Structure is an advanced modular building solution engineered to deliver outstanding strength, reliability, and installation efficiency for modern industrial facilities. Designed around a high-performance steel space frame system, this structure offers an excellent balance between lightweight components and maximum load-bearing capability, making it one of the most effective choices for large-span warehouse construction, logistics hubs, distribution centers, and bulk-storage buildings.


    Built from certified prefab steel, including Q235B and Q355B grades, the warehouse structure ensures long-term performance under demanding conditions. Its tri-circular arch shell or square pyramid grid system provides superior geometric stability and optimized stress distribution, allowing spans from 96 to 120 meters without internal columns. This creates a fully open indoor area that maximizes usable floor space—an essential advantage for warehousing, machinery storage, and material handling operations.


    The structure employs a bolt-ball joint connection system, one of the most reliable solutions for space-frame assembly. Each connection point is precisely machined to guarantee excellent fit, structural integrity, and simplified on-site construction. The standardized conical connectors ensure compatibility across modules, allowing flexible design modifications and smooth integration with mechanical or roofing systems. These features significantly reduce installation time compared to traditional welded steel structures.


    To ensure long-term durability, all members are coated with a high-performance epoxy zinc-rich primer, providing robust resistance against corrosion, moisture, and industrial pollutants. This makes the solution ideal for coastal regions, humid climates, and high-dust environments. When paired with lightweight roofing materials, the structure achieves a balanced combination of reduced self-weight and high structural stiffness, contributing to better energy efficiency and lower maintenance costs over its long service life.


    The warehouse structure is engineered according to GB50583-2020, JGJ7-2010, and 07SG531, meeting stringent requirements for wind resistance, snow load, seismic performance, and general safety. Every project is customized based on local climate conditions, logistic requirements, and client specifications. The flexible modular design supports multiple installation methods, including high-altitude assembly, block-by-block erection, and the highly efficient sliding method for long-span roofs.


    This prefab steel warehouse structure stands out for its exceptional adaptability. Clients can request custom dimensions, architectural forms, colors, and load parameters to match warehouse automation systems, conveyor lines, or storage equipment. The system is also fully compatible with modern thermal panels, skylights, ventilation units, and photovoltaic installations.


    With its 50-year design service life, CE and ISO9001 certifications, and proven performance in global markets, this steel space-frame warehouse solution provides a dependable and scalable option for companies seeking to expand operations or upgrade existing facilities. Its advanced engineering, combined with rapid installation and superior durability, ensures a long-term return on investment and stable building performance.


    By choosing this prefab steel warehouse structure, businesses gain a high-quality industrial building designed to meet future capacity needs, enhance operational efficiency, and withstand challenging environmental conditions, while maintaining a cost-effective construction process. The result is a strong, customizable, and enduring warehouse solution built to support heavy-duty industrial operations for decades.
