In 2024, Xinguangzheng delivered a 90x45x12m steel structure logistics storage facility in Nigeria, designed as a warehouse building to meet the surging demands of the e-commerce sector. Facing Nigeria’s unique tropical climate and logistical challenges, we leveraged steel structures to achieve rapid construction and cost optimization.
Client Needs
Our client, a fast-growing logistics company in Nigeria specializing in e-commerce distribution and regional trade, operates from Lagos—West Africa’s commercial hub. With Nigeria’s e-commerce market growing at over 15% annually, their existing warehouses couldn’t handle the spike in order volumes, especially during peak seasons. Additionally, Nigeria’s tropical environment poses risks of corrosion, frequent heavy rains causing flooding, and soft soils complicating foundation design. Traditional concrete buildings take 8-14 months to construct, cost over $120 per square meter, and lack flexibility for rapid business expansion.
Through in-depth discussions and on-site surveys, we identified the following core needs:
- High-capacity storage: At least 4,050 square meters to support multi-tier racking and automated sorting systems.
- Rapid delivery: Project timeline compressed to 9 weeks to seize market opportunities.
- Environmental resilience: The building must withstand flooding and high humidity, with energy-efficient design reducing operating costs by 20-25%.
- Modular design: Support for future expansions, such as adding cold storage or office spaces.
Drawing on our West African project experience, we analyzed soil and climate data to help the client understand potential risks. Steel’s high strength and flexibility made it the ideal choice, with its column-free, large-span design boosting space utilization by 20%, perfectly suited for dynamic logistics storage facilities.
Solutions
For this logistics storage facility, we implemented an optimized portal steel frame system, with all components prefabricated in our factory, adhering strictly to ISO 9001 quality standards and Nigeria’s National Building Code (NBC). This approach minimized construction errors and ensured high-quality delivery.
Key specifications include:
Dimensions and layout: 90 meters long, 45 meters wide, 12 meters high (eave height), with a total area of 4,050 square meters. The column-free design optimizes racking layout and logistics flow.
Structural components:
- Frame: High-strength steel beams (ASTM A572 Grade 50 compliant), with a load-bearing capacity of 45 kN/m², suitable for heavy sorting equipment.
- Roof and cladding: 0.5mm galvanized steel sandwich panels with an R-value of 3.5, tailored for Lagos’ hot, humid climate, maintaining comfortable indoor conditions.
- Foundation: Reinforced concrete pile foundations with bolted steel base plates, addressing soft soils and enabling easy installation or disassembly.
Customized features:
- 300-square-meter mezzanine office with a control room for real-time logistics management.
- Pre-installed interfaces for automated sorting systems, supporting high-speed conveyors and robotic sorting.
- Flood and ventilation design: Elevated foundation by 30 cm, combined with sidewall louvers and roof vents, reducing cooling energy use by 15%.
Implementation Process
At Xinguangzheng, we prioritize transparency, providing weekly progress updates to ensure no delays. This industrial warehouse project was completed in three phases, with a total timeline of just 7-9 weeks, far surpassing traditional construction efficiency.
- Prefabrication phase (2-3 weeks): Components were precisely cut and assembled in our modern factory, with digital quality control reducing waste by 35%. Every steel beam underwent rigorous testing.
- On-site preparation (10 days): Addressing Lagos’ soft soils, we used pile foundation designs and completed foundation pouring. Modular transportation ensured smooth logistics.
- Assembly and testing (3 weeks): Bolted connections enabled rapid erection without on-site welding. After installing sorting lines and ventilation systems, we conducted structural and waterproofing tests.
To tackle high humidity, we applied double-layer epoxy anti-corrosion coatings, drawing on our experience from projects in Ghana and Benin, reducing carbon emissions by 25% compared to concrete construction.
Final Results
Post-delivery, client feedback exceeded expectations:
- Cost and efficiency: Construction costs were 22% lower than concrete (total investment around $230,000), with annual maintenance under $4,000. Sorting efficiency improved by 20% due to the optimized column-free racking layout.
- Durability: During Lagos’ 2024 rainy season floods, the facility sustained zero damage, proving the reliability of our flood-resistant design.
- Sustainability and expandability: Energy-efficient design cut consumption by 15%, meeting EDGE green certification standards. The modular structure supports future expansions, with the client already planning a cold storage addition.
- Return on investment: First-year operating costs dropped by 12%, with a payback period of about 4 years.
Tunde Afolabi, Project Manager: This 90x45x12m facility is a masterpiece. Xinguangzheng’s modular approach and quick build kept us on budget and ahead of schedule. The scalable design is already sparking plans for expansion.
