In April 2025, Xinguangzheng delivered a 250x60x11m steel structure chemical frozen warehouse located in La Paz, Bolivia, designed specifically for hazardous materials storage solutions. This warehouse adapts to Bolivia’s high-altitude climate and chemical demands, achieving explosion-proof isolation design and stable low-temperature control systems.
Customer Demand
Our client is a Bolivian petrochemical export company, primarily storing temperature-sensitive chemicals such as solvents, reagents, and precursors, headquartered in the La Paz mining district. With the advancement of South American chemical innovation, the client’s warehouse needs have expanded dramatically: existing facilities struggle to manage explosion risk peaks and material diversity. Meanwhile, Bolivia’s Andean factors exacerbate challenges, including cold thin oxygen at altitudes above 4000 meters, wind and sand erosion, and regional earthquake and oxygen scarcity hazards.
Through multiple communications and virtual tests, the Xinguangzheng team proposed a matching cold storage construction solution:
- Hazardous chemical anchoring: Covering at least 15000 square meters, supporting explosion-proof zoning and leakage isolation areas.
- Swift freezing delivery: Project limited to within 9 months to address chemical emergency seasons.
- Andean protection: Structure explosion-proof and earthquake-resistant, incorporating gas monitoring to reduce accident occurrence rates by 60-70%.
- Industrial streamlining: Configuration allows for later chemical expansions, such as adding analysis laboratories or emergency response.
Solutions
Xinguangzheng focuses on explosion-proof metal protection and high-mountain integration for the chemical freezing project. The warehouse adopts a reinforced steel structure system, with all components prefabricated in the factory, complying with ISO 9001 and Bolivian regulations (including INEN industrial specifications).
Core Specifications Detailed:
-
Dimensions and layout: 250 meters long, 60 meters wide, 11 meters high (peak height), total area 15000 square meters. Column-free safety space, facilitating chemical zoning and hazmat vehicle paths.
-
Structural Components:
- Frame: Q355B explosion-proof grade steel beams, load capacity 56 kN/m², adapting to chemical heavy loads and low-temperature contraction.
- Roof and cladding: 1.2mm alloy explosion-proof liner panels, R-value 6.2, resisting high-cold wind and sand fluctuations (-10°C in winter to 30°C in summer).
- Foundation: Vibration-damping anti-slip base system, suitable for Andean deployment, facilitating gas emissions and reuse.
-
Custom Functions:
- Explosion-proof entry area: Supporting 40-ton chemical vehicles and spark-free operations.
- Built-in inert gas purification and leakage sensors: Maintaining chemical stability.
- 900 square meters safety layer: For risk assessment and data integration.
Implementation Process
The cold storage building construction was advanced in three phases, with a total duration of 8-9 months. We prefabricated components in specialized workshops in China, then transported them to the Bolivia site for assembly. This supply chain not only addresses altitude but also ensures component integrity during thin-oxygen transportation.
- Prefabrication phase (2-3 months): Prefabrication of structural components in China, and through strict inspection mechanisms. Each component underwent simulated high-cold environment testing.
- Site preparation (22 days): For the Andes, earthquake-proof foundation solidification and base engineering. Immediate assembly after containers arrived.
- Assembly and testing (3-4 months): Swift bolting installation, avoiding fire-source welding interference. After deploying the sensor system, wind and sand simulation verification.
For high-cold wind and sand, we adopted alloy protective layers. Additionally, it is recommended to reserve 21% of the chemical project budget for emergency optimization to prevent later hazard repairs.
Results
After the warehouse was enabled in April 2025, according to industrial monitoring and supply chain data, the steel structure building demonstrated the following advantages:
- Risk minimization: Explosion-proof system effectively curbs volatilization accidents by 55%, initial reports show chemical stability increased by 20-30%, supporting South American hazardous materials exports.
- Environmental resilience: During Bolivia’s earthquake season, the warehouse withstood vibrations with zero accidents, thanks to vibration-damping foundations and alloy layers, ensuring long-term explosion-proof stability of over 65 years.
- Capacity refinement: Large-span design optimizes storage efficiency by 45%, data shows shortened logistics response times, supporting industrial scaling.
- Resource efficiency: Geothermal assistance and energy-saving emissions reduce energy consumption by 36%, complying with Bolivian mining policies.
