I. Project Background: World-Class Architectural Aesthetics and Engineering Challenges

*Project Name: Hangzhou Olympic Sports Center Main Stadium (“The Giant Lotus”)

*Design Highlights: Composed of 28 large petals and 27 smaller petals, employing an extremely complex spatial twisted steel structure system.

*Material Challenges:

Complex Structural Stress: The enormous cantilever span requires extremely high-strength supporting materials.

*High Environmental Humidity: Located near the Qiantang River, the high humidity necessitates extremely high corrosion resistance from the materials.

*Strict Construction Precision: Every connection point and fastener is crucial to the safety of tens of thousands of spectators.

II. Shandong Runhai Steel's Material Supply Solution

For the unique structural form of the "Big Lotus," Shandong Runhai Steel provided a "multi-category, high-standard" supply matrix: Products supplied include: high-strength seamless steel pipes (excellent torsional and bending resistance and dimensional tolerance control), carbon steel thick plates (uniform structure, excellent Z-axis stress performance (resistance to lamellar tearing)),hot-dip galvanized steel coils (uniform coating thickness, resistant to salt spray corrosion).

III. Technical Depth and Case Highlights

1. The Core Strength Supporting the "Petals": High-strength Seamless Steel Pipes

2. The "Ballast" of Core Nodes: Carbon Steel Thick Plates

3. "Stainless Steel Guarantee" in the Details: 304 Stainless Steel Fasteners

4. Long-Term Protection: Weather Resistance of Hot-Dip Galvanized Products

IV. Significance and Achievements of Cooperation

1. Quality Creates a Landmark: Shandong Runhai's products withstood the high standards of the Asian Games, providing strong evidence of the company's supply capabilities in the field of ultra-large irregular spatial structures.

2. Full Life Cycle Guarantee: Through the combined application of high-performance materials, the "Lotus" project achieved international leading levels in energy conservation, environmental protection, and building lifespan.

3. Enhanced Brand Reputation: Participation in the construction of national landmark stadiums signifies that Shandong Runhai Steel has entered the first tier of China's high-end construction steel supply chain.

From the blooming of the "Lotus" on the banks of the Qiantang River to the precise engagement of every stainless steel bolt, Shandong Runhai Steel transforms architects' inspiration into a solid reality with high-quality steel products. In the future, Shandong Runhai will continue to focus on high-end stadium construction projects, contributing "steel power" to more world-class projects.
