Q355 steel and seismic design solution for two warehouses in Argentina
Recently, the cross-border delivery of two large-scale modern steel structure warehouse projects in Buenos Aires, Argentina, managed by Canglong Group through a one-stop full-service solution, has been successfully completed. The projects are currently in the high-standard installation and construction phase at the project site.
Located in Buenos Aires, the capital and core logistics hub of Argentina, the project consists of two high-standard single warehouses with building dimensions of 42 meters (length) × 33 meters (width) × 7.25 meters (eave height) and 66 meters (length) × 22.52 meters (width) × 6.74 meters (eave height), respectively. Facing the specific geological load requirements and high-frequency turnover needs of industrial and commercial buildings, the Canglong technical team introduced a new prefabricated industrial and commercial building solution: a “Q355B high-strength steel frame + high-level seismic-resistant structural design.”
Q355B H-beams and Double-Slope Structure Design
Buenos Aires, as a regional logistics hub, has stringent standards for the overall mechanical stiffness, seismic performance, and space utilization of its warehouse buildings:
- Double-Slope Roof Frame System: Both warehouses utilize a classic double-slope roof portal frame structure design, which not only achieves excellent mechanical self-balancing over large spans but also provides efficient roof drainage during the South American rainy season.
- Q355B High-Strength H-Beams: The core load-bearing beams and columns are entirely constructed with high-tensile, low-alloy Q355B grade premium H-beams. Before leaving the factory, they undergo high-standard shot blasting and multiple layers of heavy-duty anti-corrosion coating, providing the two warehouses with a robust steel core resistant to seismic activity, wind loads, and fatigue.
- High-corrosion-resistant interlocking substructure: The structural subsystems (roof and wall purlins) are fully equipped with high-rigidity galvanized C-shaped steel, precisely interlocked with column supports, tie rods, and high-strength bolts, effectively dispersing multi-directional vibrations and wind loads, and resisting the long-term invisible corrosion from the high humidity of coastal air.
Full-chain service from design to installation
Addressing the common pain points faced by cross-border industrial and commercial infrastructure projects, such as language barriers, cumbersome customs procedures, and lack of overseas installation guidance, Canglong Group has implemented a completely reliable All-in-One closed-loop managed service:
- Full lifecycle coverage: Canglong Group provides its Argentine clients with a one-stop service encompassing digital structural detailing, precision manufacturing of a complete set of steel structure components from major manufacturers, international booking and transportation, customs clearance, and professional on-site installation guidance in Argentina, truly achieving worry-free delivery.
- Complete kit included in container: This includes H-beam main frame, galvanized C-beam purlins, tie rods, bracing, inter-column supports, high-flow drainage gutters, and a full set of high-strength connecting bolts. 100% CNC high-precision prefabrication and punching are completed at the Chinese production base. The entire package is shipped directly to the destination port in Argentina, completely eliminating the risk of work stoppages due to missing parts.
Dry, modular, rapid assembly
Since all components are 100% standardized prefabricated, upon arrival at the Buenos Aires, Argentina site, the construction team performs rigid assembly with bolts, eliminating 100% welding and secondary cutting on-site.
This modular, dry construction method makes on-site construction extremely environmentally friendly and efficient, not only halving the overall installation period but also significantly reducing expensive local installation labor costs.
Project Progress and Outlook
Currently, the main steel frame and support system at the Buenos Aires, Argentina project site are undergoing high-quality installation at a rapid pace. These two modern warehouses, integrating high-level earthquake resistance, high-strength corrosion resistance, and rapid assembly, will soon be officially completed and put into operation with a brand-new look. This once again demonstrates to the Latin American market the core strength and service commitment of Canglong Group in the global industrial and commercial prefabricated building field.
