Pre-Engineered Multi-Story Steel Structure Warehouse 3-5 Floor H/Box Column

Our multi-story steel-structure warehouses feature a core load-bearing framework constructed from high-strength steel and utilize a "factory prefabrication plus on-site assembly" construction model. Specializing in multi-level storage designs ranging from two to six stories, we offer fully customized solutions—from compact 1,000 m² multi-story warehouses to expansive 80,000 m² multi-story logistics centers—tailored to each client's specific site dimensions, storage requirements, and industry characteristics.

Strictly adhering to universal standards for warehouse planning and design, our structures are fully compatible with modern warehousing operational needs, including heavy-duty racking systems, automated sorting equipment, and forklift traffic. Furthermore, they incorporate an integrated, multi-functional layout that seamlessly combines storage, office space, and sorting areas, making them the ideal choice for land-intensive warehousing environments.

The overall structure is divided into four major systems: the main load-bearing framework, flooring, envelope, and vertical transportation. Constructed in full compliance with regulations, the facility ensures stability and safety.

• Main Load-Bearing Framework: Utilizes high-strength Q355B H-section and box-section steel beams and columns, while the purlins consist of hot-dip galvanized C- and Z-section steel. Featuring column spacing of 6-12 meters and standard large spans of 18-30 meters, the structure is assembled via a combination of bolting and welding. Integrated with a comprehensive bracing system, it offers exceptional structural stability and facilitates rapid installation.
• Flooring System: Consists of a composite structure featuring profiled steel decking and reinforced concrete. Designed to support live loads ranging from 5.0 to 12.0 kN/m², the floor surface is flat, wear-resistant, moisture-proof, and anti-slip. It can be finished to an ultra-flat standard to accommodate forklifts and AGV equipment, while also providing sound insulation and vibration damping to meet the operational demands of both light- and heavy-duty warehousing.
• Envelope System: Primarily employs fire-resistant, color-coated steel sandwich panels, offering superior thermal insulation, moisture resistance, and soundproofing. The ground level allows for the optional use of lightweight masonry walls, while loading and unloading zones come standard with extended rain canopies, featuring scientifically designed drainage systems to ensure robust protection.
• Vertical Transportation System: Configured on an as-needed basis with freight elevators and lifting platforms ranging from 2 to 10 tons in capacity. Integrated with standard loading docks, the system ensures efficient traffic flow and material transfer, effectively catering to the practical operational conditions found in both northern and southern regions.
• Auxiliary Support Features: Include standard robust foundations, high-strength connection components, and comprehensive ventilation and drainage facilities. Fire safety systems are designed in strict accordance with national standards, and the entire facility is equipped with collision protection barriers to ensure durability and ease of maintenance.

Multi-Tiered, High-Efficiency Expansion: Significant Land Savings
Featuring a multi-story vertical design ranging from 2 to 6 levels, this system multiplies storage capacity within the same footprint—effectively alleviating issues related to land scarcity and high rental costs. Floor heights are strategically zoned: lower levels are optimized for heavy cargo and large-scale operational machinery, while upper levels are designated for light cargo storage, sorting, and office space. This approach maximizes spatial utilization, making it ideally suited for both industrial park and urban warehousing sites.

High-Strength, Stable, and Durable: Secure and Worry-Free for Heavy Loads
The main structural frame is constructed from high-strength Q355B steel, designed in strict compliance with architectural load-bearing codes. The floor system offers a wide load-bearing range, capable of accommodating various heavy-duty applications—including the storage of heavy cargo and the parking of heavy machinery. Structural components feature dual anti-corrosion treatment, complemented by professional fire-resistance and seismic-resistant designs. Highly resistant to wind and corrosion, the structure boasts a designed service life of up to 50 years, ensuring long-term stability and reliability with minimal operational and maintenance risks.

Factory Pre-Fabrication and Assembly: Rapid Completion and Operation
With 90% of structural components pre-fabricated to standardized specifications in the factory, on-site assembly is achieved primarily through bolted connections, ensuring convenient and efficient construction without the need for extensive on-site hot-work welding. Compared to traditional brick-and-concrete structures, the construction timeline is drastically reduced. This high-efficiency process minimizes disruption to existing business operations, allowing for rapid completion and commissioning to accelerate the return on investment.

One-Stop Customization: Versatile for All Industry Scenarios
We offer comprehensive customization options covering the number of floors, structural spans, ceiling heights, and internal layouts. Ancillary facilities—such as freight elevators, loading/unloading platforms, ventilation and insulation systems, and fire safety/drainage infrastructure—can be integrated as required. The system flexibly adapts to a wide range of commercial warehousing scenarios, including cold chain storage, e-commerce sorting centers, heavy industrial storage, strategic material reserves, and industrial park warehouses.

Eco-Friendly and Energy-Efficient: Lower Total Cost of Ownership
Featuring a high steel recyclability rate, the construction process is environmentally friendly and generates minimal waste, fully complying with green building standards. The structure's lightweight design requires less extensive foundation work, resulting in lower overall construction costs compared to traditional multi-story buildings. Long-term maintenance is simple, and the structure offers the flexibility for easy disassembly, expansion, or even relocation and reuse—delivering superior overall value and return on investment.

Distinguished by their vertical expansion capabilities, flexible customization options, and high durability, our multi-story steel-structure warehouses are widely deployed across various storage environments where land resources are scarce. We provide specialized vertical storage solutions for diverse industries, with particular suitability for the following sectors:

• E-commerce & Logistics: E-commerce sorting centers, express courier transit hubs, and large-scale logistics centers requiring integrated vertical storage and sorting capabilities. For instance, automotive parts manufacturers can effectively double their storage capacity—thereby resolving complex parts storage challenges—by utilizing multi-story steel platforms.
• Industrial Manufacturing: Raw material warehouses, finished goods depots, heavy equipment storage facilities, and multi-story storage extensions for production workshops. These structures are ideally suited for the categorized storage of goods featuring a wide variety of types and specifications.
• Cold Chain Storage: Multi-story temperature-controlled (constant-temperature/low-temperature) warehouses capable of integrating thermal insulation systems and refrigeration equipment to facilitate the segregated storage of goods requiring different temperature environments.
• Urban Storage: Storage facilities situated in land-scarce areas—such as urban outskirts and industrial parks—designed to maximize land utilization efficiency and minimize rental costs.
• Specialized Applications: Reserve depots for emergency supplies, multi-story storage for agricultural products, and multi-story warehouses for construction materials. These facilities can be customized to include specialized areas, such as clean-room-grade storage zones.,
