Customized Large-Span Prefabricated Steel Structure Warehouse with 50-Year Service Life

Factory-prefabricated steel components allow for on-site assembly with minimal wet construction work, reducing the construction period by 40%-60% compared to concrete warehouses. Construction is not restricted by rainy seasons or low winter temperatures, enabling year-round work and allowing enterprises to secure tenants and generate rental income earlier.

Steel beams and trusses enable ultra-wide single spans of 24-48 meters with few or no internal columns, allowing for flexible layouts of racking, forklifts, and sorting lines. Ceiling heights of 9-14 meters are easily achievable, accommodating high-rise racking and automated storage and retrieval systems (AS/RS), thereby significantly increasing storage capacity per unit of land.

Steel structures weigh only one-fifth to one-third of concrete structures, resulting in lower foundation loads and eliminating the need for complex piling treatments on soft soil. Foundation engineering costs are reduced for the same plot size, land utilization is higher, and storage capacity is significantly increased on the same footprint.

Standardized components are mass-produced, ensuring stable costs per square meter. Integrated systems for foundations, exterior walls, and roofing are mature, and future modification or expansion costs are far lower than those for brick-concrete or concrete structures.

Steel components can be dismantled, relocated, and reused; expanding the facility, partitioning warehouses, or adding sorting areas and cold chain compartments does not require large-scale wall demolition. Overhead cranes, hoists, rooftop solar panels, canopies, and loading docks can be quickly installed, accommodating diverse business models such as e-commerce warehousing, cold chain logistics, bulk goods storage, and 3PL services.

Floor and roof load-bearing capacities are adjustable to support heavy-duty racking, AGV automation equipment, and large forklifts. Roofs can support solar panels, ventilation systems, and fire-suppression piping, meeting the installation requirements of modern smart warehousing facilities.

Roof and wall panels feature a modular design, allowing for the replacement of individual damaged sections; this ensures rapid repairs and minimizes downtime. The primary steel framework is durable and virtually free from common issues such as wall cracking or water leakage, requiring minimal routine inspection and maintenance. Utilities (plumbing, electrical, and fire safety systems) can be surface-mounted along steel columns and beams, eliminating the need to break into walls for modifications or repairs.

Components feature uniform specifications, and design, production, and construction processes are standardized, enabling the batch replication of warehouse park chains. Blueprints, costs, and schedules can be rapidly standardized and estimated, making the model ideal for logistics real estate companies acquiring land and building warehouses at scale.
