Corrugated Steel Culverts in Turkey and Africa

Analysis of China's Corrugated Steel Culverts in Turkey and Africa: Opportunities, Challenges, and Strategy

On the Balıkesir-Manisa Highway in Turkey, a 475-foot culvert repair project was completed in just two weeks without stopping traffic – thanks to the excellent performance of Chinese corrugated steel culvert technology.

Turkey Market: Innovation Opportunities in Mature Infrastructure

As a bridge connecting Europe and Asia, Turkey's infrastructure development has been fast. In recent years, continued government investment in transport, energy, and utilities has created rich market opportunities for Chinese corrugated metal culvert companies. In the Saklıvadi culvert project on the Balıkesir-Manama highway, the old concrete culvert needed replacement due to long-term use and heavy vehicles.

The project used the ViaCon corrugated steel pipe culvert system. Installation took only two weeks, without interrupting traffic, significantly faster than traditional methods. This success story highlights the core advantages of corrugated steel culverts: fast construction and minimizing traffic disruption. The original culvert was massive and had significant earth fill above it.

Using traditional demolition and rebuild methods would have meant a long-term closure of this vital link between the Marmara and Aegean regions, causing major economic impact. Turkey's infrastructure sector has some operational barriers for foreign companies, including restrictions on local projects, strict environmental policies, and conditional land acquisition. Chinese companies entering this market need to pay special attention to these rules and plan their project strategies carefully.

Africa Market: A Broad Field with Diverse Needs and Potential

Infrastructure development in Africa is growing rapidly, and there's a diverse range of needs for Chinese corrugated steel culvert products. Application levels and focus areas vary noticeably between different regions and countries. In Congo, the steel pipe market includes welded steel pipes and seamless steel pipes, mainly used in water supply, oil gas, and chemical industries. Market research shows Congo's steel pipe market will keep growing steadily in the coming years, offering potential chances for related businesses.

Geotechnical Considerations and Installation Protocols

Chinese companies in Africa have built a business model centered on infrastructure leadership supported by manufacturing. For example, companies from Henan province are building railways, roads, and power projects in Ethiopia, Kenya, and others, accounting for 40% of their African business.

These projects heavily use Chinese-made steel and pipe products, creating good conditions for using corrugated steel culverts. In Africa, currency devaluation and payment defaults are major risks for Chinese companies. For instance, after a Chinese company signed an order in Nigeria, the local currency's value fell sharply against the US dollar, causing the contract value to drop and turning a 15% profit into a 7% loss.

As the world demands more durable, economical, and environmentally friendly infrastructure, steel corrugated pipe culverts are expected to prove their value in more engineering scenarios. They offer a reliable solution for future infrastructure construction needs.

Application Cases: Technical Advantages Proven On-Site

Real-world use in Turkey and Africa has fully demonstrated the technical strengths of Chinese corrugated steel culverts:In the Turkish Balıkesir-Manisa Highway Project, the corrugated metal culvert system was installed inside the existing structure, avoiding large-scale excavation and demolition. This greatly reduced the project's environmental impact. This method not only shortened the construction time but also significantly lowered costs, offering a new approach for similar infrastructure upgrade projects.

The project widely used Chinese-made steel sheet piles and steel pipe piles. These materials are reliable, high-quality, and offer clear advantages in efficiency, delivery time, and cost control. Technically, research shows that large-span arch culverts have better mechanical performance and stress relief with EPS boards compared to circular culverts of the same span. Placing EPS boards changes the vertical earth pressure and maximum equivalent stress in a non-linear way for both culvert types.

This finding provides an important reference for selecting the right corrugated steel culvert technology in these two markets.
