5000m2 steel structure warehouse with office in Chile
In Chile on the west coast of South America, facing the demand for upgrading the logistics industry and efficient warehousing, Canglong Group has tailored a modern logistics warehouse project with a total construction area of 5000 square meters for local customers, focusing on functional and regional adaptation.
This complex building, integrating large-capacity warehousing and comfortable offices, not only serves as the core function of the client’s regional distribution center but also, through precise technological adaptation and meticulous attention to detail, has become a benchmark in Chilean logistics infrastructure.
Project Positioning
The project focuses on a core logistics hub in central Chile, serving the transshipment and distribution of agricultural and industrial products in the region. The client’s specific requirements included: the warehouse must handle an average daily throughput of 5,000 standard pallets, with a clearance height suitable for high-bay racking. The supporting office area needed to accommodate daily management, customer reception, and data monitoring functions, while also addressing the challenges of high humidity and large diurnal temperature variations characteristic of coastal Chile.
Based on this, Canglong Group proposed an integrated warehousing and office design strategy. Centered on a 4304㎡ high-standard warehouse, complemented by a two-story office area measuring 39.8m × 13.4m × 7m, the total building area is 5000㎡, achieving the dual goals of efficient operation in the work area and comfortable and convenient office space.
Technical Breakthrough
Addressing the core requirements of heavy-duty, durable, and weather-resistant logistics warehousing in Chile, Canglong Group carried out customized design from the main structure to the enclosure system.
1. Main Structure: Q355H Steel and Steel Trusses
Warehouse Main Structure: A large-span lightweight frame. The warehouse uses Q355H steel as the beam-column system, with main steel columns spaced 12 meters apart and main beams spanning 24 meters. Rigidly connected by high-strength bolts, it forms 72 independent frames. The high yield strength and excellent weldability of Q355H steel meet the heavy-duty requirements under a 10.5-meter clearance while optimizing the cross-section to control steel consumption within a reasonable range. Stiffening ribs were added to key nodes. Considering the 50-year return period wind load and seismic fortification requirements of the Chilean coastal region (dimension 7), the structural safety factor reached 1.8 times, verified by ANSYS finite element analysis.
Office Area Roof: Steel truss and EPS sandwich panels, balancing span and lightweight design. The two-story office area roof uses a 12-meter span steel truss structure, with a truss height of 1.8 meters, rigidly connected to the main structure through embedded parts at the column tops. 50mm thick EPS sandwich panels are laid on the truss, reducing the roof’s self-weight while providing thermal insulation through the closed-cell structure of EPS. Actual measurements show that the summer top-floor temperature is 6-8℃ lower than traditional color steel roofs, and winter indoor heat loss is reduced by 40%.
2. Enclosure System: EPS sandwich panels and functional doors and windows
Warehouse Enclosure: 50mm EPS sandwich panels, providing both waterproof and fireproof protection. The warehouse’s exterior walls and roof are constructed using 50mm thick EPS sandwich panels, with a 0.5mm galvanized steel sheet on the outer side and a 0.4mm color-coated steel sheet on the inner side. They are secured using tongue-and-groove joints and self-tapping screws, with seams filled with weather-resistant sealant. The hydrophobicity of the EPS core material (water absorption ≤1%) and the fire resistance rating of the panels themselves (B1 level) perfectly suit Chile’s alternating rainy and dry climate, while also reducing the impact damage to the building envelope from typhoons or hail.
Functional doors and windows: Enhancing accessibility and natural lighting, the warehouse is equipped with 6m x 6m electric roller shutter doors, supporting remote control to facilitate rapid access for high-reach forklifts. The office area features double-pane glass doors, ensuring a clear entrance while reducing air conditioning energy consumption through heat-insulating coatings. Windows are made of PVC plastic steel, with a wind pressure resistance of up to level 9, suitable for the strong winds of Chile’s coastal environment, while also offering >80% light transmittance to improve natural lighting in the office area.
