Guangzhou New Baiyun Airport Terminal

Project overview

The main building of the New Baiyun Airport terminal is 325 m × 235 m, using about 21,000 tonnes of steel, with a roof area of about 165,000 m² and a 30-year design anticorrosion life, a representative early large-hub airport steelwork anticorrosion project in China. The project is included in the infrastructure section of the COSCO Kansai case book.

Anti-corrosion (fire protection) challenge

• The herringbone composite columns of the main building are 14.7–35.7 m tall; the large-span steel roof demands high coating adhesion and long-term performance;
• Indoor and outdoor environments are managed by zone: outdoor topcoats are UV-resistant, indoor ones also provide fire protection (2-hour fire resistance limit);
• Welds, high-strength bolt joints and other areas require on-site touch-up to ensure system continuity.
