Benchmark Case | Steel Sheet Piles Exported to the Philippines for Coastal Reclamation & Port Construction

Our client is a leading infrastructure construction company in the Philippines, undertaking a key coastal reclamation and port expansion project in Cebu. As the Philippines faces increasing demand for coastal development and port upgrading to boost maritime trade and local economic growth, the project required high-performance steel sheet piles to form reliable retaining structures. The core requirements included strong load-bearing capacity, excellent corrosion resistance (to adapt to the tropical marine environment), and easy installation to meet the tight construction schedule.

Product Solution: Customized Steel Sheet Piles for Philippine Coastal Projects

Based on in-depth communication with the client and a comprehensive analysis of the project's geological conditions (tropical coastal soil, high salinity seawater) and construction requirements, we provided a tailored solution with hot-rolled U-type steel sheet piles, the most widely used type in coastal and port construction. The key product advantages and customizations are as follows:

- High-Quality Base Material: Adopted Q355B (equivalent to ASTM A36) carbon structural steel as the base material. This grade features excellent tensile strength (minimum 470 MPa) and yield strength (minimum 355 MPa), ensuring strong structural stability and load-bearing capacity for the retaining walls. It can effectively resist soil pressure and seawater impact during coastal reclamation.

- Corrosion-Resistant Treatment: Customized hot-dip galvanizing treatment (with a zinc coating thickness of ≥85μm) was applied to the steel sheet piles. This treatment forms a dense protective layer, significantly enhancing resistance to corrosion from seawater, salt spray, and humid tropical air, extending the product's service life to over 25 years in the marine environment.

- Specifications: According to the project, we supplied steel sheet piles (width: 400mm/500mm, height: 6m-12m, thickness: 10mm-16mm). The U-type design ensures easy interlocking during installation, forming a seamless and leak-proof retaining structure, which is crucial for coastal reclamation projects to prevent seawater infiltration.

Application Scenario & Implementation

Our steel sheet piles were mainly used for two core parts of the project:

1) Coastal reclamation retaining walls: Forming a stable barrier to enclose the reclamation area, preventing soil erosion and seawater intrusion during land formation;

2) Port wharf foundation reinforcement: Strengthening the wharf's foundation structure to withstand the load of berthing ships and cargo handling equipment.

To ensure the smooth progress of the project, our team provided full-process support:

1) Conducted pre-installation technical training for the client's construction team, explaining the interlocking skills and quality control points of the steel sheet piles;

2) Coordinated efficient maritime logistics, completing customs clearance and delivery to the Cebu construction site ahead of the scheduled time;

3) Dispatched technical personnel to the site for on-site guidance during the installation phase, ensuring the retaining structure met the design requirements.

Project Outcome & Client Feedback

With our high-quality steel sheet piles and professional technical support, the coastal reclamation and port expansion project was completed on schedule. The U-type steel sheet piles formed a stable, leak-proof retaining structure, which effectively guaranteed the smooth progress of land reclamation and port construction. The hot-dip galvanizing treatment has also been verified to resist the harsh marine environment, laying a solid foundation for the long-term service of the project.

The client highly recognized our products and services: "The steel sheet piles from ROYAL STEEL fully meet our project's technical requirements. Their excellent load-bearing capacity and corrosion resistance are perfectly adapted to the Philippine coastal environment. The customized specifications and efficient delivery have helped us save construction time significantly. We are very satisfied with the cooperation and look forward to partnering with ROYAL STEEL for more infrastructure projects in the Philippines."
