I. Project Background: A Cultural Pearl on the Canal

*Project Name: Beijing City Library (Beijing Municipal Administrative Center Library)

*Architectural Features: The roof is supported by 144 "tree-like" pillars, resembling a ginkgo forest; it boasts the world's tallest self-supporting glass curtain wall.

*Material Standards: Extreme Precision: To accommodate the ultra-large glass curtain wall, the verticality of the steel support structure and the flatness of the welds must reach the millimeter level.

*Visual Integration: The steel structure must balance load-bearing and decorative functions; the surface coating and the flatness of the substrate must be highly consistent.

*Safety Margin: The core structure must support the ultra-heavy roof and the large internal cantilevered space; the materials must achieve the highest level of fatigue resistance.

II. Shandong Runhai Steel's Customized Supply Matrix

Addressing the complex spatial geometry of the library, Shandong Runhai Steel provided a "high-performance, customized" product portfolio: High-strength precision seamless steel pipes, carbon steel medium-thick plates (Q355/Q420), 304/316L stainless steel plates, and high-performance galvanized sheet coils and pipes.

III. Technological Highlights and Ingenious Applications

1. Building the "Forest" Framework: Precision seamless steel pipes; 2. Withstanding "Extremely Heavy" Loads: High-performance medium-thick plates; 3. Safeguarding a "Constant Temperature" Environment: Environmentally friendly galvanized products.

IV. Cooperation Value and Project Achievements

1. Contributing to "Sub-center Speed": Facing the project's tight construction schedule, Shandong Runhai Steel achieved precise material delivery through "digital logistics scheduling," ensuring seamless connection at key nodes.

2. Benchmarking International Top-Tier Technology: Successfully serving this project, which has won multiple international architectural awards, once again demonstrates Shandong Runhai Steel's leading level in the field of high-end art infrastructure.

3. Low-carbon production, green empowerment: The company's production processes strictly adhere to green manufacturing standards, contributing to the Beijing City Library's achievement of a three-star green building rating.

From every "ginkgo pillar" to every stainless steel detail, Shandong Runhai Steel's products in the Beijing City Library perfectly blend the strength of steel with the elegance of culture. This library is not only a haven for readers but also a showcase of China's high-standard manufacturing capabilities. Shandong Runhai Steel will use this project as an opportunity to continue its deep cultivation in the field of ultra-high-standard public buildings, contributing to more future landmarks.
