As a professional provider of steel structure solutions, we successfully delivered a high-performance galvanized steel structure system for a gas station project in Réunion. Leveraging advanced galvanization technology and precise engineering design, the project fully meets the harsh environmental adaptation requirements and operational safety standards of tropical coastal regions.
Réunion, located in the Indian Ocean, features a tropical maritime climate with high humidity, strong salt spray corrosion, and frequent temperature fluctuations. The gas station, as a key infrastructure, has strict demands for structural durability, corrosion resistance, and operational safety.
Long-term resistance to salt spray and humid air corrosion, ensuring a service life of over 20 years.
Compliance with local building codes for wind load and seismic performance.
High structural stability to support the gas station canopy and related equipment.
Efficient construction cycle to minimize on-site construction impact.
Targeting the project's characteristics, we customized a comprehensive galvanized steel structure solution, focusing on material selection, structural optimization, and process control.
We adopted high-quality Q355B carbon structural steel as the base material, paired with hot-dip galvanization treatment. The zinc coating forms a dense protective layer with a thickness of ≥85μm, which achieves cathodic protection for the steel substrate. This effectively resists salt spray erosion and humid air corrosion, far exceeding the corrosion resistance of traditional painting processes.
The canopy frame adopted a space truss structure, which balances structural strength and material efficiency, reducing wind resistance while enhancing overall stability.
Key joints were designed with reinforced connections and seamless galvanization treatment to avoid corrosion weak points.
The structural design fully considered local wind load (up to 0.65kN/m²) and seismic intensity requirements, verified through finite element analysis.
Dimensional accuracy inspection for each component, with a tolerance within ±2mm.
Zinc coating thickness detection using magnetic thickness gauges, ensuring full coverage without missing plating.
Non-destructive testing (NDT) for key welds to ensure welding quality meets AWS D1.1 standards.
The prefabricated components were transported to the project site and assembled efficiently, completing the main structure installation in 15 working days, which shortened the on-site construction cycle by 30% compared to traditional methods.
After project completion, the galvanized steel structure has passed local authoritative third-party testing, with the following results:
Corrosion resistance meets ISO 1461 standards, capable of withstanding long-term salt spray environment.
Structural bearing capacity and stability fully comply with Réunion's building code requirements.
The surface of the galvanized components is smooth and uniform, with no peeling or rust, ensuring aesthetic and functional integration.
The client confirmed in the acceptance report: "The galvanized steel structure solution perfectly addresses the environmental challenges of Réunion. The professional design, strict quality control, and efficient delivery of the team have ensured the project's success, and we recognize it as a reliable long-term cooperative partner."
This project fully demonstrates the unique advantages of galvanized steel structures in tropical coastal infrastructure:
Superior corrosion resistance, reducing long-term maintenance costs.
High structural strength and stability, adapting to harsh weather conditions.
Prefabricated production, improving construction efficiency and quality control.
Environmentally friendly and recyclable, in line with global green building trends.
We continue to focus on the R&D and application of steel structure technologies, providing professional, reliable, and customized solutions for global infrastructure projects. For gas stations, industrial facilities, commercial buildings, and other projects in extreme environments, we have mature technical capabilities and project experience to support your project success.
