Canglong Group assists the construction of 480 square meter steel godown in Uruguay
Canglong Steel Structure's modern warehousing project for its Uruguayan client serves as a benchmark for green warehousing in South America, utilizing a standardized portal frame system. Canglong provided an efficient, economical, and tropical monsoon-adapted all-steel structure solution. The building measures 20x24x8 meters, with a floor area of 480 square meters, perfectly suited to Uruguay's mild and humid climate with an average annual temperature of 22°C and annual rainfall of 1200mm.
Canglong Group provided end-to-end integrated services, encompassing detailed design, customized materials, international logistics coordination, on-site installation guidance, and post-construction technical training. This ensured the project was efficiently completed within four months, achieving a 25% reduction in construction time and an 18% cost optimization, earning high praise from the client and setting a new industrial standard for warehousing construction in Uruguay.
Structurally, the project employs a portal frame system, with main beams and columns constructed from Q355H high-strength low-alloy hot-rolled steel, conforming to GB/T 1591 standards. With a yield strength of 355 MPa and a tensile strength of 510 MPa, it possesses excellent weather resistance and wind pressure resistance, capable of withstanding category 12 typhoons and effectively coping with the frequent rainfall and strong winds of Uruguay's monsoon climate.
The beam-column connection utilizes high-strength bolt friction connection (M16 grade, torque 800 N·m), significantly reducing the construction period by 40% compared to traditional welding processes, improving structural seismic resistance, and facilitating later maintenance and expansion. The purlin system uses galvanized C-shaped steel with a zinc coating thickness ≥80 g/m², conforming to ISO 1461 standards. Lightweight and highly corrosion-resistant, it effectively supports the enclosure system and resists the risk of rust in humid and hot environments, ensuring a maintenance-free lifespan of over 15 years.
The enclosure system fully integrates energy conservation and functionality:
Wall System: Utilizes 75mm thick polyurethane sandwich panels with a thermal conductivity of 0.024W/(m·K) and a thermal resistance of 4.2m²·K/W, achieving a 95% thermal resistivity and significantly reducing temperature fluctuations within the storage area. It also boasts Class A fire resistance (combustion rating GB 8624-2012 A1) and 120dB sound insulation, ensuring cargo safety and employee comfort.
Roof Structure: Employs 50mm thick polyurethane sandwich panels (double-layer aluminum core, density 45kg/m³) with a UV-resistant coating, forming a double waterproof barrier (waterproof rating reaching GB/T 18245-2000 Class I), achieving 0% leakage even with Uruguay's average annual rainfall of 1200mm. Simultaneously, the light-colored reflective design increases solar radiation reflectivity to 65%, effectively mitigating the heat island effect. The indoor temperature is 6°C lower than with traditional roofs, reducing annual air conditioning energy consumption by 20%.
The entire service process showcases Canglong's technical strength and localization capabilities:
Design Phase: Full parametric design based on BIM technology (Tekla Structures model) optimizes portal frame spans, reducing on-site cutting rates to below 3%, ensuring maximum utilization of storage space.
Material Supply: Q355H steel is directly supplied from high-quality Chinese steel mills, and after third-party testing by SGS, its chemical composition and mechanical properties meet 100% standards. Galvanized C-shaped steel and polyurethane sandwich panels are both ISO 9001 certified and comply with Uruguay's SIRP environmental standards.
International Logistics: Coordinated full container shipping (40-foot high cube containers) at Qingdao Port, with full temperature control and protection throughout, completing sea freight to Montevideo Port, Uruguay within 15 days, with a loss rate controlled below 0.3%.
This project reduces carbon emissions by 30% (compared to traditional concrete structures), becoming a model for the Uruguayan warehousing sector. Furthermore, by leveraging the superior insulation properties of polyurethane sandwich panels and the rapid construction advantages of portal steel frames, Canglong Steel Structure provides a replicable green warehousing template for the Uruguayan warehousing industry. With a dual-engine model of technology-driven development and localized services, Canglong Steel Structure continues to empower the South American market, helping Uruguayan warehousing construction move towards a new stage of high efficiency, low carbon emissions, and intelligent manufacturing.
