Yitong successfully delivers Europe's largest corrugated steel closed structure

We are proud to announce the successful delivery of Europe’s largest corrugated steel closed structure, fully designed and manufactured by our company. This landmark project represents a major achievement in structural steel engineering and underscores our leadership in delivering large-scale, innovative infrastructure solutions.

Comprehensive Corrugated Steel Product Solutions

At Yitong, we offer a diverse range of corrugated steel structures designed to meet various engineering needs, especially in environments requiring fast installation, long service life, and heavy load-bearing capacity. Our main product lines include:

Corrugated Steel Pipe (CSP): Used in culverts, drainage, and underpasses, our CSP features high strength-to-weight ratio, resistance to corrosion, and simple on-site assembly.

Corrugated Steel Arch & Box Culverts: Designed for large-span requirements, these structures are ideal alternatives to traditional concrete bridges and tunnels, offering easier transport and reduced foundation requirements.

Integral Corrugated Steel Structures & Multiplate Systems: Modular design allows for flexible assembly in various shapes and sizes, meeting custom demands for road, railway, and mining infrastructure.

Advantages of Corrugated Metal Structures

High Strength & Load Capacity: Our optimized corrugation profiles improve the section modulus by up to 30% compared to flat steel plates, enabling structures to withstand loads exceeding 500 kN/m² in heavy traffic and industrial environments.

Modular & Lightweight Design: Typical corrugated steel structures weigh 40–60% less than equivalent concrete alternatives, reducing transportation costs by up to 35% and installation time by up to 50%, significantly accelerating project schedules.

Corrosion-Resistant Coatings: Our galvanized coatings reach a thickness of 275 g/m² (G90 standard), with options for aluminized or polymer coatings that can extend service life beyond 50 years in harsh environmental conditions, such as coastal or industrial areas.

Environmentally Friendly: Made from 100% recyclable steel, our products support circular economy goals. Compared with traditional concrete structures, corrugated steel fabrication reduces CO₂ emissions by approximately 40% over the lifecycle.

Customization & Engineering Support: Leveraging over 20 years of R&D, our technical team has designed over 1,000 customized structures worldwide, providing tailored solutions that optimize material use and structural efficiency according to specific terrain and load requirements.
