Dominican Republic Project

The Dominican Steel Structure Project is located in the industrial zone of the Port of Santo Domingo, Dominican Republic, and represents a quintessential large‑span industrial steel structure project in the Caribbean region. The project primarily comprises large industrial warehouse buildings, equipment towers, and associated ancillary steel structures, serving local logistics and warehousing, building‑material processing, and industrial production. It stands as a flagship example of Chinese enterprises’ overseas deployment of prefabricated steel structures. Situated in a coastal environment characterized by high temperatures, high humidity, and frequent severe typhoons, the project imposes structural requirements for wind resistance, corrosion protection, and weather durability that far exceed those of typical domestic steel‑structure projects.

In consideration of the local coastal conditions—characterized by frequent winds and a hot, humid climate—the project adopts a composite structural system combining large‑span portal frames with heavy‑duty lattice towers. The factory building area employs a lightweight portal frame structure, providing extensive column‑free open spaces to accommodate storage and loading/unloading operations. The industrial equipment towers utilize a lattice truss system, offering high overall stiffness, excellent resistance to overturning and wind pressure, and robust performance under the region’s severe typhoon loads, making them well suited to the extreme climatic conditions of island environments. The structural load paths are clear, and the overall stability is strong, ensuring optimal adaptation to complex outdoor operating conditions overseas—marked by high corrosion and significant wind loads.

The project adheres rigorously to overseas American steel‑structure codes and incorporates local climatic standards in its material selection, implementing a tiered configuration for primary and secondary structural members. Key load‑bearing components—such as the tower’s main trusses, factory building girders, and columns—are fabricated from Q355B high‑strength steel, enhancing the overall structural strength and resistance to deformation. Roof purlins, enclosure elements, and auxiliary connectors are made from Q235B steel, enabling cost control while meeting international construction standards. The project employs a domestically standardized prefabricated construction approach: all steel components undergo precision cutting, assembly and welding, shaping and alignment, and anti‑corrosion pre‑treatment at domestic factories, then are shipped by sea to the site for on‑site erection. This results in high component accuracy and efficient on‑site construction.
